	Description		Read-only	Idempotent	Open world
`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 before using either number.

`get_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.	Daily-averaged historical price series.

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

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.
