The API and MCP documentation will be published here when access opens at launch.

Developer documentation

Reference pages for the API and the MCP server will be published here when access opens. These rules already hold for every response.

What every response follows

• An estimate always comes with its low and high values, a confidence word and the date it was measured.
• A value that cannot be estimated comes as "not measured" with a reason, never as a zero.
• Errors share one shape, with a short code and a plain message.
• Keys are personal, short-lived and can be revoked at any time.
• Responses carry results only, not how they were calculated.

Until then
