The free endpoints

No key, no rate limit, CORS open. These are the same numbers the pages render, so you can check any figure on this site against its source.

/api/tokens.json Every stock, with all its listings.
/api/tokens/nvda.json One stock, with its holders and its event tape.
/api/events.json Corporate actions, scheduled and past.
/api/registry.json The chains and issuers each listing points at.
/api/tradfi.json The off-chain reference price beside each token.
/llms.txt An index of the whole site, for a model that would rather read text.
/mcp A read-only MCP (Model Context Protocol) server. POST, streamable HTTP, no API key.

Data licensed CC BY 4.0. An MCP server answers the same lookups at https://stocksonchain.io/mcp. A metered bulk feed for automated callers is described on the agent page; no human reader is ever charged, asked to sign in, or asked to connect a wallet.
