Influencer marketing has become a $22+ billion industry, and the creator data infrastructure behind it is evolving just as fast. In 2026, brands and platforms aren’t just looking for a dashboard to browse creators — they need programmable access to influencer data, audience intelligence, fraud detection, and campaign workflows that plug directly into their tech stacks via dedicated influencer marketing APIs.
That’s where creator marketing APIs come in. Unlike general social media APIs — which are designed to help you publish content, pull analytics for your own accounts, or manage community interactions — influencer marketing APIs are purpose-built for a different job: finding the right creators, verifying their audiences, accessing creator data at scale, and powering campaigns through code.
We’ve spent weeks evaluating the major influencer data APIs based on real technical criteria: database depth, endpoint quality, documentation, pricing transparency, and how fast you can go from zero to production. Here are the best influencer marketing APIs in 2026.
2. Modash API
Best for high-volume influencer search across Instagram, TikTok, and YouTube
Modash indexes over 350M profiles and offers two distinct API products: a Discovery API for filtered search with pre-analyzed data, and a Raw API for live, unfiltered profile and content data. The Discovery API is designed for finding new creators based on audience demographics, engagement rates, and fake follower scores. The Raw API streams real-time posts, follower lists, and metrics — ideal for campaign tracking and content monitoring.
The developer experience is strong. Modash provides REST endpoints with clean JSON responses, comprehensive documentation, and quickstart guides. The credit system is transparent, with different endpoints consuming credits at predictable rates. Where Modash falls short compared to broader solutions is platform coverage — it’s limited to three networks — and the price of entry for API access, which puts it out of reach for smaller teams.
Strengths
- 350M+ profiles with strong audience demographic data
- Dual API model (Discovery + Raw) for different workflows
- AI-powered search endpoint for innovative discovery use cases
- Clean documentation and predictable credit-based pricing
Limitations
- Limited to Instagram, TikTok, and YouTube only
- High entry price (~$16K–$20K/year) with no monthly option for API
- No verified email enrichment — relies on publicly listed contacts
- Separate pricing from the Modash platform product
Pricing~$16K–$20K/year
3. HypeAuditor API
Best for audience quality verification and influencer vetting at scale
HypeAuditor has carved out a strong niche as the go-to influencer marketing API for audience authenticity analysis. With a creator database of over 219 million profiles, their Influencer Reports API returns over 35 metrics per profile — including audience quality scores, engagement authenticity, demographic breakdowns, and historical performance data. The Discovery API lets you filter creators by niche, audience location, and engagement patterns, while the Campaign Management API tracks posts, mentions, and hashtags.
Where HypeAuditor genuinely excels is trust data. If your platform needs to help brands vet creators before committing budget, the depth of their fraud detection and audience quality signals is best-in-class. The Suggester API is also handy for building typeahead search into your UI. The trade-off: no public pricing, no self-serve onboarding, and the integration requires working through their sales team.
Strengths
- Industry-leading fraud detection and audience authenticity scoring
- 35+ analytics metrics per profile with historical tracking
- Campaign management API for post tracking and reporting
- Covers Instagram, YouTube, TikTok, X, and Twitch
Limitations
- No public pricing — requires enterprise sales engagement
- No verified email data for outreach workflows
- 219M+ profiles is strong but less than the 340M+ discovery-first leaders
- Not built for bulk enrichment or CRM-style data feeds
Pricing: Custom (enterprise)
Best for Fortune 500 brands managing large-scale creator programs
CreatorIQ is the enterprise heavyweight. Its API feeds into a broader platform used by brands like Disney, Unilever, and Sephora to manage thousands of creator relationships, run campaigns, track performance, and automate reporting. The AI-powered discovery engine analyzes over a billion public social accounts and indexes 15M+ enriched profiles with proprietary “Integrity Quotient” scoring for audience health.
The API itself is robust — it supports campaign workflows, CRM data feeds, content-first search (analyzing images, captions, and context beyond just keywords), and integrations with enterprise tools like Tableau, Shopify, and Salesforce. The catch? Getting started requires a multi-month implementation, annual contracts starting around $30K, and a dedicated onboarding process. This isn’t an API you evaluate over a weekend hackathon.
Strengths
- AI-powered content analysis for smarter creator matching
- Deep campaign management and reporting through API
- White-label capabilities for agencies and enterprise
- Integrations with Shopify, Salesforce, Tableau, and more
Limitations
- Starting at ~$30K/year with annual commitment
- Multi-month onboarding required — no self-serve
- 15M indexed profiles is smaller than discovery-focused APIs
- Designed for large enterprise, overkill for startups or mid-market
Pricing~$30K–$36K/year
5. Upfluence API
Best for e-commerce brands integrating influencer data into their sales stack
Upfluence’s API follows REST architecture with OAuth2 authentication and JSON responses. It’s designed to pull creator database access, campaign data, and real-time reporting into your existing tech stack. The real strength is the e-commerce angle: deep integrations with Shopify, WooCommerce, Magento, and Klaviyo let brands identify influential customers from their own buyer data, generate tracked affiliate links, and monitor creator-driven sales directly.
The API is available on their higher-tier plans (Growth and Enterprise), so you’ll need an active Upfluence subscription to access it. The documentation includes interactive examples for real-time testing, which accelerates integration. However, the 12-month minimum contract and the sales-first onboarding process make this a poor fit for teams that want to experiment before committing.
Strengths
- Deep e-commerce integrations (Shopify, WooCommerce, Amazon)
- Identify influencers from your own customer database
- Full campaign lifecycle management via API
- Interactive API docs with real-time testing
Limitations
- API only available on higher-tier subscription plans
- 12-month minimum contract required
- ~9M vetted profiles — smaller database than discovery-first tools
- No standalone API access — requires full platform subscription
From ~$478/month (12-month contract)
6. Phyllo API
Best for: Creator economy apps needing verified private metrics
Phyllo takes a fundamentally different approach from every other API on this list. Instead of scraping or aggregating public data, it uses OAuth-based authentication to fetch first-party metrics directly from platforms — with the creator’s explicit consent. This means you get private data like real revenue figures, actual reach (not estimated), detailed audience breakdowns, and engagement data that public APIs can’t surface.
The SDK supports iOS, Android, React Native, Flutter, and web, and can be integrated in under a week. Phyllo covers 20+ platforms, including social, gaming, music, and writing platforms. The trade-off is that every data point requires the creator to authenticate — which makes Phyllo unsuitable for bulk discovery or prospecting. It’s designed for apps where creators onboard voluntarily, like income verification tools, creator CRMs, or monetization platforms.
Strengths
- First-party, consent-based data — most accurate metrics available
- Revenue and earnings data (unique to Phyllo)
- Multi-platform SDKs with fast integration times
- 20+ platforms including gaming, music, and writing
Limitations
- Requires individual creator OAuth — no bulk discovery
- Enterprise pricing (~$20K/year) with no true free tier
- Not useful for prospecting or outreach use cases
- Dependent on each platform’s own API limitations
Pricing: Custom (sandbox free, production ~$20K/yr)
7. CreatorDB API
Best for brand-level influencer marketing intelligence and campaign research
CreatorDB differentiates itself by offering not just influencer data, but brand intelligence. Their API lets you pull data on any brand’s influencer marketing campaigns — including which creators they work with, campaign timelines, and performance benchmarks. For agencies and competitive intelligence tools, this is a powerful feature that most other APIs don’t offer.
The influencer data covers YouTube, Instagram, TikTok, Facebook, and Threads with pre-built reports for quick insights. Pricing follows a flexible credit-based model with monthly and yearly options. The database is smaller than the discovery giants, but the brand-level intelligence makes it a strong pick for specific use cases like competitive analysis, pitch deck preparation, and market research.
Strengths
- Unique brand intelligence data — see any brand’s creator partnerships
- Flexible credit-based pricing that grows with usage
- Pre-built reports for quick integration
- Self-serve onboarding available
Limitations
- Smaller database (~10M+ profiles) compared to discovery-first APIs
- No verified email enrichment
- Limited campaign management capabilities
- Newer entrant with a smaller track record
Pricing: Credit-based (monthly/yearly plans)
8. Influencer Hero API
Best for brands that want discovery, outreach, and campaign tracking in one API
Influencer Hero positions its API as a full-stack solution: discovery, campaign tracking, and audience insights through a single integration. The platform has published multiple case studies showing results for DTC and e-commerce brands, with features for product seeding, affiliate link generation, and performance reporting baked into the API.
Pricing starts at $249/month, which is competitive for a tool that bundles discovery with campaign management. The documentation focuses on practical integration patterns, and the API covers Instagram, YouTube, TikTok, X, and Twitch. The main downside is transparency — the database size isn’t publicly disclosed, which makes it harder to benchmark against dedicated data APIs for discovery-specific use cases.
Strengths
- Full campaign lifecycle API (discovery → outreach → tracking → payment)
- Competitive pricing starting at $249/month
- Email enrichment included for outreach workflows
- Strong case studies from DTC and e-commerce brands
Limitations
- Database size not publicly disclosed
- Smaller platform coverage compared to data-first APIs
- Newer API product — less established developer community
- Sales-driven onboarding for API access
PricingFrom $249/month
9. Traackr API
Best for enterprise teams focused on influencer ROI attribution and spend optimization
Traackr is built for the data-driven enterprise marketer who needs to justify every dollar of influencer spend. The platform provides access to creator discovery across 13 social platforms with 13M+ indexed influencer profiles, but its real value is in measurement: performance benchmarking, ROI attribution, budget optimization, and competitive spending analysis. If your team needs to answer “what did we get for our influencer budget?” at a granular level, Traackr surfaces that creator data programmatically.
The platform supports global campaigns with multi-market coverage and is used by brands like L’Oréal, Samsung, and Colgate-Palmolive. However, it’s firmly enterprise-tier: annual contracts starting around $32.5K per year, sales-led onboarding, and API access limited to higher-tier plans (Plus plan at $55K+/year). Traackr’s database is curated rather than exhaustive, which reflects its focus on influencer data quality and depth over raw scale.
Strengths
- Industry-leading ROI attribution and spend analysis
- 13 platform coverage with global multi-market support
- Performance benchmarking and competitive spend intelligence
- Trusted by major global brands for budget optimization
Limitations
- Curated database (~13M profiles) — not built for bulk discovery
- Enterprise pricing starting ~$32.5K/year (API access at $55K+)
- No self-serve or sandbox testing available
- Not optimized for bulk discovery or contact enrichment
Pricing: ~$32.5K+/year (API on Plus plan ~$55K+)
10. GRIN API
Best for DTC brands managing ongoing creator relationships and product seeding
GRIN is a creator management platform that’s popular among direct-to-consumer brands like Skims, Gymshark, and Colourpop. Its influencer marketing API focuses on relationship management workflows: creator recruitment, product seeding, content approvals, affiliate tracking, and payment processing. It integrates with Shopify, WooCommerce, Magento, Salesforce, and Slack, making it a natural extension of existing DTC tech stacks.
GRIN’s creator data spans over 190M influencer profiles across Instagram, TikTok, and YouTube, with a discovery tool that includes customer-based recruitment (scanning your own e-commerce data for brand advocates), lookalike analysis, and social listening. The API is designed to power workflows within the GRIN ecosystem rather than provide standalone data access. Pricing starts at approximately $2,500/month with custom enterprise plans, and they now offer a 30-day free trial.
Strengths
- Full relationship lifecycle management (recruit → seed → track → pay)
- Deep Shopify, WooCommerce, and Magento integrations
- 190M+ influencer profiles with customer-based recruitment
- 30-day free trial and month-to-month plans now available
Limitations
- No standalone API data access — tied to GRIN platform subscription
- Pricing starts ~$2,500/month — high for smaller brands
- Limited to 3 platforms (Instagram, TikTok, YouTube)
- Primarily focused on DTC e-commerce; less suitable for agencies or platforms
Pricing: From ~$2,500/month (30-day free trial)
How to Choose the Right Influencer Marketing API for Your Creator Data Needs
Not every influencer marketing API on this list competes for the same job. The right creator data API depends entirely on what you’re building and where influencer data fits into your product. Here’s a quick decision framework based on common use cases:
If you’re building a creator discovery or search tool: You need the largest possible database with strong filtering. Influencers.club (340M+ across 47 platforms) and Modash (350M+ across 3 platforms) are the two strongest options. The key differentiator is platform breadth and pricing — Influencers.club covers far more networks at a fraction of the cost.
If you’re enriching CRM or outreach workflows: Verified email data is non-negotiable. Influencers.club leads here with email enrichment built into the core API. GRIN and Influencer Hero also provide contact data, but with smaller databases and higher price ceilings.
If you’re building a creator economy app (finance, verification, monetization): Phyllo is the main choice. Consent-based authentication gives you access to private metrics — including earnings — that no public data API can touch.
If you’re an enterprise brand managing a large-scale program: CreatorIQ and Traackr are built for this. They combine discovery with campaign management, reporting, and ROI attribution — but expect six-figure annual commitments and multi-month implementations.
If you’re an e-commerce brand tracking influencer-driven sales: Upfluence and GRIN both offer deep Shopify and WooCommerce integrations with affiliate link tracking. Upfluence edges ahead on the breadth of e-commerce integrations.
If you need competitive brand intelligence: CreatorDB is the niche pick, while influencers.club is the most comprehensive. CreadorDB’s brand-level campaign data lets you see which creators your competitors are working with and how those partnerships are performing.
