API for developers

Summary

The /api/v1/ endpoints expose the project's model outputs in machine-readable form. They're the Pro tier's headline value proposition: every probability the public site renders, available as clean JSON for research notebooks, data journalism, fantasy tooling, and analytics workflows.

This is v1 — a deliberately small, stable surface: flat JSON rows, no nested expansion. Authenticate with a Bearer API key or a session cookie (see below).

Try it with no setup: GET /api/v1/sample/ is public — no account, no key. It returns the top-5 tournament-win probabilities so you can see the data s…

Every endpoint except the public /api/v1/sample/ needs a credential. Two ways to authenticate:

Bearer API key (recommended) — generate a long-lived key at /account/api-key/ and pass it as Authorization: Bearer otp_live_…. One token, no cookie juggling — the friendly path for headless / CI / agent clients, and what the hosted MCP server at /api/mcp/ uses.
