groundcheck.seiche.info extract

https://groundcheck.seiche.info/extract

needs params

Claim extraction for agent verification loops: split text into independently checkable atomic factual claims via auditable rule-based decomposition (no LLM guessing), with a signed receipt bound to the input hash. The cheap first step of the loop — extract here, then ground what matters via /verify or /check.

Bazaar lists this endpoint, but when we called it we got HTTP 422 instead of a payment challenge.
