Changelog

Changes to the MCP server and the REST API, newest first. Additive changes keep older clients working; anything that breaks a client is announced here first.

2026-10-27

• Developer documentation published at terra-lab.ai/docs, with a markdown copy of every page and /docs/llms.txt.
• Tool descriptions state the radius_m limits of get_satellite_image, so agents get a valid call on the first try.
• HEAD works on /v1/openapi.json and /v1/meta/pricing, for link checkers.

• Out of free calls or balance, the 402 answer points to the account page in account_url.

• New price grid: 100 calls included every month, then 5 per 1,000 calls and 0.05 per satellite image, from a prepaid balance. No subscription. See Pricing.
