Put the record in your agent.

One key, REST and MCP.

Other feeds tell you what was filed. This one tells you which sources have historically been worth following, with the evidence attached. Free tells you what happened; paid tells you who was right.

Get a free key

The free plan includes 3 tools and 500 requests a day. No card. Sign in and the key is yours in one click.

Call it directly

Send the key as the x-api-key header.

The full description lives at /openapi.json.

Or hand it to an agent

The MCP server is published as @alphayou/mcp. It registers only the tools your key may call.

claude mcp add alphayou \
  --env ALPHAYOU_API_KEY=ay_your_key \
  -- npx -y @alphayou/mcp

Limits, stated plainly

Free3 tools, 500 requests a day
Starter5 tools, 10,000 requests a day
Scale7 tools, 50,000 requests a day

Every response says what is left of the day in X-RateLimit-Remaining. Over the limit you get a 429 and a Retry-After, never a silent truncation. Paid plans are priced but not billable yet.

Every performance number the API returns carries its period, benchmark, method, as-of date, sample size and full range including the losers. Numbers without those six are not published. Redistribution needs a separate licence, the same as every comparable feed. This is market research, not investment advice.
