Capacités

Outils

6 outils
get_carbon_prices
Current 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 before using either number.

get_market_summary
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.

get_price_history
Carbon price history
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 the response — the archive began on 2026-08-27, so early windows are necessarily short.

get_story
Get one 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.

list_sources
Monitored 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.

search_news
Search VCM 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 newest-first. Use `get_market_summary` first if you do not know what tags or date range to ask for.
