KeyAPI

KeyAPI is an API finder tool. KeyAPI bundles social data from 20+ platforms behind one REST key, with CLI, Agent Skills and MCP support for AI agents, live streams, historical archives and monthly credit plans starting at $59.

KeyAPI is a unified REST API that routes social media data from more than 20 platforms through a single key and a single authentication header. Instead of wiring up separate credentials for TikTok, Instagram, YouTube, LinkedIn, Facebook, Twitter/X, Reddit, Threads, Pinterest, Amazon, Google, Douyin and others, a developer calls one endpoint pattern and swaps the platform segment. The homepage positions the product as an AI agent first platform: requests carry an Authorization Bearer token, and there are no required SDKs to install. The service is aimed at developers, automation engineers and AI builders who need to read social data programmatically: user profiles, posts, reels, comments, followers, transcripts, product reviews, search results and trend signals. Real-time streams sit alongside historical archives powered by EchoTik, which the site says reach up to 1,000 days of trend data. That combination suits analytics dashboards, model training sets and market research pipelines where a mid-length lookback matters as much as today's numbers. There are three integration routes beyond plain REST calls. A CLI lets agents or scripts hit endpoints from a terminal, Agent Skills expose the catalogue to AI assistants that discover and invoke tools on their own, and MCP support connects the API to model context protocol clients. The claim is that natural language requests can be resolved into the correct underlying call, so less plumbing sits between a question and the data. Published figures cite 99.9 percent uptime, under 500ms average latency and preview responses in the low hundreds of milliseconds. Where KeyAPI competes is against juggling official platform APIs, maintaining scrapers, or buying from data resellers. The single-key model and predictable credit quotas reduce integration overhead, and paid tiers add historical depth, rate limit boosts and SLA terms. The tradeoff is commitment to a third party: credit allowances are fixed per plan, the free tier is short-lived, and compliance with each platform's terms rests on the vendor rather than the caller.
