• search_news

  Search carbon.fyi's curated voluntary carbon market story archive. Each story is an editorially clustered summary of one development, written from one or more original reports, and always carries the original source name and URL. Supply at least one filter; results are…

• get_story

  Fetch a single story by its id, including every source that reported it. Story ids are permanent — a published story keeps its id and its public URL indefinitely — so they are safe to store.

• get_carbon_prices

  Current voluntary carbon credit prices from two independent sources: per-category minimum/median price and available supply across the Carbonmark marketplace catalog, and spot prices per Klima Protocol carbon class. The two are NOT comparable — read the `caveats` field on each…

  Daily-averaged historical price series. This archive exists only because carbon.fyi records it three times a day: no upstream API serves a historical carbon price series, so these observations cannot be obtained anywhere else and cannot be re-derived. Check `seriesStartsAt` in…

• get_market_summary

  One call for orientation: how much of the archive is available, when it last updated, the story-tag breakdown (use these as `tag` values for search_news), and the current price table. Start here.

• list_sources

  The publications, registries and integrity bodies carbon.fyi monitors. Useful for judging coverage — a topic absent from the archive may simply not be covered by these sources.
