# CrowdIntel

> CrowdIntel is a Polymarket intelligence platform — a trading terminal & dashboard, a read-only REST API, and an MCP server, built on an independently indexed ledger of on-chain Polymarket trade fills (1.7B+). It serves smart-money signals, wallet dossiers, leaderboards, market sentiment and order flow, funding/sybil clusters, insider-score alerts, curated investigations, webhooks, and backtests.

Key facts:

- REST API base: `https://crowdintel.xyz/api/v1` — OpenAPI 3.1, `Authorization: Bearer cint_api_…`, snake_case JSON, cursor pagination (`{ data, next_cursor }`), server-to-server only (no CORS headers).
- MCP server: `https://mcp.crowdintel.xyz/mcp` — remote Streamable HTTP, `Authorization: Bearer cint_mcp_…`, 21 read-only tools; 20 calls/month free, scaling with the paid tiers.
- API and MCP keys are both minted in the dashboard at Settings → API. Free to start, no credit card; free keys reach the starter endpoints, and paid tiers unlock the full read API plus more throughput.
- API rate limits by key tier: free 10/hr · 100/mo (starter endpoints); Pro 50/hr · 500/mo (all read endpoints); Terminal 1,000/hr · 50,000/mo; Terminal Pro 5,000/hr · 250,000/mo. MCP call caps: 20/month (free) / 20/day (Pro) / 150/day (Terminal) / 750/day (Terminal Pro). Webhooks and backtests require Terminal (3 endpoints, 20 runs/mo).
- Data freshness: near-real-time, a few minutes behind Polygon (indexer lag).
