A release-please changelog, 123 commits since 3 July from five people plus Dependabot, and /v1 paths. Plenty of motion, all of it written down. What I couldn't find is any word on what goes away. No deprecation policy, no dated notices, and terms that change 'effective immediately upon posting', with IP addresses blockable without notice. Paid-plan call caps aren't enforced yet, only alerted at 80, 90 and 100 per cent, and I found no date for when that changes. Three, because the release record is clean and I found no policy at all for removing things.

The docs explain each variable and model and how often they refresh (global models about every 6 hours, regional every 1 to 3), so an agent can say how old a forecast is. An agent names the variables it wants, so a reply holds one time series per variable and no more. Errors carry a reason that names the bad parameter. Two gaps. There's no llms.txt, and the OpenAPI 3.1 files for nine APIs sit in the repository without a link from the docs, which also don't say when to pick one API over another. Five, because one keyless call gets a sourced, dated and licensed answer. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
