# Get Platforms

> Unauthenticated discovery endpoint that declares which V1 intelligence surfaces are supported, partial, or unsupported per provider platform.

The platform capability matrix: which V1 intelligence surfaces are supported, partial, or unsupported per provider platform. Read it once at integration time so you know which endpoints return data for Polymarket versus Kalshi before you call them.

This is an unauthenticated discovery endpoint, so you can fetch it without an API key.

```bash theme={null}
curl "https://api.0xinsider.com/api/v1/platforms"
```

Use it to gate features client-side instead of hardcoding per-platform assumptions that drift as coverage expands.

openapi: 3.1.0
info:
  title: 0xinsider API
  description: >-
    Find your edge on Polymarket and Kalshi. Every wallet graded, every trade
    scored, every outlier flagged. API exposes trader grades, whale trades,
    smart money signals, and insider detection for AI agents, trading bots, and
    research tools. Normal API requests use a 30-second server timeout that
    returns HTTP 408 Request Timeout with an empty body when exceeded. Public
    REST /api/v1/* endpoints, excluding /api/v1/mcp, use Bearer-token based
    non-credentialed browser CORS: any Origin may call with Authorization,
    Content-Type, If-None-Match, Idempotency-Key, and Mcp-Session-Id request
    headers. Remote MCP at /api/v1/mcp is non-credentialed, but still validates
    Origin against the 0xinsider/localhost allowlist per MCP Streamable HTTP
    DNS-rebinding guidance. Successful browser CORS preflight responses
    advertise Access-Control-Max-Age: 86400. Browser JavaScript may read
    X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, Retry-After,
    ETag, X-Request-Id, X-Request-Cost, X-Batch-RateLimit-Limit,
    X-Batch-RateLimit-Remaining, X-Batch-RateLimit-Reset, Mcp-Session-Id, and
    X-Mcp-Error-Code response headers. Credentialed first-party routes such as
    /api/keys, /api/billing, and auth endpoints remain restricted to configured
    0xinsider origins.
