What is KeyAPI?
Key features
Unified social API
One API key and one response envelope to pull data from 20+ social and commerce platforms including TikTok, Instagram, YouTube, Twitter/X, LinkedIn, Reddit, Amazon, Facebook, Pinterest and Google.
REST and JSON
Plain REST endpoints returning structured JSON, so no platform-specific SDKs are needed to integrate.
Creator and profile data
Fetch user profiles, follower and subscriber counts, and professional details such as LinkedIn skills and company information.
Content and comments
Retrieve videos, posts, reels, stories, comments, replies, hashtag and music data, and search and discovery signals.
Commerce and shop data
Access product information, reviews, shop and seller profiles, category intelligence and livestream data for commerce use cases.
AI agent endpoints and MCP
An AI-agent-first architecture with dedicated AI endpoints and Model Context Protocol integration for use inside LLM workflows.
Credit-based usage
Subscriptions grant a monthly credit allowance that is consumed per API call and resets every 31 days on renewal.
Pros & cons
Advantages
- A single API key and consistent response format replaces juggling separate integrations for each social network.
- Coverage spans 20+ platforms across social media and commerce, including hard-to-access sources like TikTok and Amazon.
- The free tier with 100 credits lets developers test the endpoints before committing to a paid plan.
- It is built for AI agents and LLM pipelines, with dedicated AI endpoints and MCP support rather than only raw data dumps.
- Published performance claims of sub-500ms average latency and a 99.9% uptime SLA give a clear service expectation.
- Both real-time and historical data are available, with up to 1,000 days of archived trends on higher tiers.
Limitations
- Credits expire and unused balance resets every 31 days, so allowance does not roll over and can be wasted if usage is uneven.
- There is no published annual billing discount or pay-as-you-go top-up, so usage must fit one of four fixed monthly tiers.
- The cost in credits per individual API call is not stated publicly, making it hard to estimate spend before signing up.
- Historical data is excluded from the free tier and unlimited history is reserved for the most expensive Ultra plan.
