x402-doctor: grade any x402 402 response for CDP Bazaar v2 indexing compliance and return the exact corrected payload.

doc-extract: structured, arithmetic-reconciled extraction of an invoice, contract, or generic document from a PDF/doc URL. Evidence-only (schema-valid, totals reconcile, dates parse, ISO-4217 currency). Charges only when the extraction reconciles; on a math/schema failure it returns the discrepancy and does not settle.

bazaar-index-check: is your x402 endpoint indexed on the CDP Bazaar? If not, format problem or backlog?

loop-detect (session-less x402): you are stuck repeating the same tool call, error, or fix with no state change between attempts. Returns the quiet-room loop-break protocol — stop signals, the two-loop hypothesis test, and when to escalate to scope-check or cascade-break. One-shot, no session.

transcribe-extract: turn any public audio, voice note, podcast, PDF, or video URL into a transcript plus its meaning — summary, ranked key points, and grounded Q&A. Deterministically validated (schema, words/min, no decode loop, meaning grounded in transcript) before it is served; evidence-only attestation, never a claim of accuracy.
