Sorsa API is a real-time, read-only REST API for public X (Twitter) data that provides 40 endpoints covering tweets, user profiles, followers, lists, communities, and action verification, returning structured JSON at up to 50x lower cost than the official X API, with a flat per-request pricing model and no developer-account approval required.
What is Sorsa API?
Sorsa API is a managed API and scraper for public X (Twitter) data, launched in 2022 (originally as TweetScout API). It accepts a single API key with no OAuth or application process and returns clean JSON across 40 endpoints. The API is read‑only by design, focusing on data retrieval and action verification — it does not support posting or account management.
Key Features
- 40 endpoints across 8 categories — Covers user profiles, tweets (including long‑form Articles), advanced search with full Twitter Advanced Search operators, followers and following, lists and communities, action verification (follow, retweet, comment, quote, community membership), and technical utilities (username/ID mapping, usage tracking).
- Flat per‑request pricing — 1 request = 1 unit on every endpoint; batch endpoints return up to 100 tweets or 200 profiles per call. No credit multipliers, no per‑endpoint tiers.
- 100 free requests to start — No credit card required; free requests never expire. Enough for up to 10,000 tweets or 20,000 profiles across all endpoints.
- 20 req/s rate limit on all plans — The same ceiling applies to Starter, Pro, and Enterprise tiers; agents and automation are not throttled on lower plans.
- Sub‑300ms p50 latency — Edge‑cached responses; 99.9% uptime with a live status page.
- AI‑native documentation — A single OpenAPI 3.0 spec URL (api.sorsa.io/v3/static/sorsa_api_v3_documentation_en.txt) works directly with Claude, GPT, Cursor MCP, and other LLM tools for one‑shot integration.
- Stable schema — When X changes its frontend or internals, Sorsa patches the data layer; the response structure stays consistent and integrations keep running without code changes.
Who is it for?
- Developers and data teams — Pull public X data for analytics, dashboards, or archival without paying enterprise API tiers or managing OAuth.
- AI engineers and LLM trainers — Fetch millions of conversations for fine‑tuning, RAG, or testing autonomous agents; the AI‑ready spec cuts integration time to minutes.
- Growth marketers and social intelligence analysts — Track competitor follower dynamics, monitor brand mentions, and run engagement verification for giveaways.
- Trading and financial signal pipelines — Poll real‑time tweet mentions of tickers at 20 req/s with sub‑300ms latency, avoiding 429 errors during volatility.
What can you do with Sorsa API?
- AI agents and autonomous workflows — Drop the docs URL into Claude, OpenAI function calling, or Cursor MCP; the model learns every endpoint and writes the full integration in one pass.
- Giveaway and campaign verification — Use dedicated
POST /check-follow, /check-retweet, /check-comment, and /check-community-member endpoints to return a true/false result, automating reward eligibility checks.
- Competitor and social listening — Export full follower and following lists (up to 200 per call), track engagement trends, and benchmark growth velocity using advanced search with operators like
min_faves: and since:.
- LLM training and fine‑tuning — Stream millions of public posts via batch endpoints and high rate limits (20 req/s) without hitting per‑post billing; over 200M tokens are streamed weekly through the API.
