The Meaning of Numbers developer portal

Docs, OpenAPI, read-only MCP, and a sandbox on this origin. There is no public API key and no OAuth login for agents. Public machine surfaces need no credential.

Quickstart

1. Fetch the agent view: /?mode=agent
2. Read the HTTP map: /docs
3. Call the public index: GET /api/v1
4. List MCP tools: POST /mcp with Accept: application/json, text/event-stream
5. Ask published pages: /ask?query=developer+resources
6. Sandbox (never charges): /sandbox or ?sandbox=1

Documentation

• API documentation
• Developer resources
• OpenAPI
• auth.md
• pricing.md
• llms.txt and /developers/llms.txt

Sandbox

/sandbox and any call with ?sandbox=1 or API-Sandbox: true never charges a card and never writes a paid reading.

What we do not ship

No Wikipedia page, npm SDK, CLI, ChatGPT app, skills.sh listing, MCP app registry listing, or minted agent token.
