# PMAxis Developer Resources

Every PMAxis developer resource in one place: REST API, MCP servers, and machine-readable files. PMAxis is the prediction market data API — real-time prices, orderbooks, trades, signals, and on-chain wallet data.

## REST API (https://api.pmaxis.trade)

- Base URL: `https://api.pmaxis.trade`
- Reference: [https://api.pmaxis.trade/docs](https://api.pmaxis.trade/docs)
- OpenAPI spec: [https://api.pmaxis.trade/openapi.json](https://api.pmaxis.trade/openapi.json)
- Status: [https://api.pmaxis.trade/status](https://api.pmaxis.trade/status)
- Sign up: [https://api.pmaxis.trade/signup](https://api.pmaxis.trade/signup) — free key, 5,000 credits/month, no credit card
- Auth: send your key as the `X-API-Key` header

Landing-site convenience proxies (no key required, cached):

- `GET https://pmaxis.trade/api/platform-stats` — total/active market counts
- `GET https://pmaxis.trade/api/ticker` — top markets by 24h volume

Errors are structured JSON: `{"error": {"code", "message", "hint"}}`.

## MCP servers

- Public discovery endpoint (no key, MCP over Streamable HTTP): `POST https://pmaxis.trade/api/mcp` — initialize, list/read documentation resources, call read-only platform tools
- Hosted SSE server (all 60+ tools, needs API key): `https://mcp.pmaxis.trade/sse?key=YOUR_API_KEY`
- npm package: `@pmaxis/mcp-server` (stdio)
- Integration guide: [https://pmaxis.trade/mcp](https://pmaxis.trade/mcp)
