Changelog
Notable changes to the Stac API and platform.
Additive changes ship without a version bump. Anything breaking gets a new
/v prefix and a migration window announced here first.
This changelog is new — entries start from here going forward. It doesn't yet cover changes made before this page existed.
2026-09-14
Token usage on image routes. /v1/images/generations and
/v1/images/edits now return a usage block in the same shape as the chat
endpoints: one token per 16×16 px block of the generated image
(completion_tokens) and of each reference image (prompt_tokens), plus the
prompt's text tokens. Image usage shows up in the Usage page and dashboard in
tokens, and falls under the plan's daily token quota (currently uncapped).
Additive — the response is otherwise unchanged.
2026-09-09
Image generation and editing. Two new endpoints,
/v1/images/generations and /v1/images/edits,
available to stacks in the image category. A prompt in and a PNG out, or up
to four reference images edited by instruction.
These routes return a second error shape alongside the API-wide
{ "detail": "..." } one — OpenAI's { "error": { "code": ... } }, with a
stable code you can branch on. Existing endpoints are unchanged.
