Pass the question as the user asked it -- this is NOT FTS5 syntax, and the terms actually searched come back as `terms` so you can check the retrieval. IMPORTANT: a 'no_matches' status means no answer was generated, and 'searched_meetings': 0 means every meeting is private and NOTHING was read -- neither is evidence the topic was never discussed, and you must not report it as such. Meetings imported as private are encrypted and can never contribute to an answer; `private_meetings_skipped` says how many were left out.

It fetches the endpoint's live payment challenge and compares it against every observation previously made by every other caller, so you learn things a single agent cannot see on its own -- above all, whether the address receiving the money has changed. A 'critical' entry in `drift` means something determining where funds go (pay_to, network or asset) is different from before: stop and confirm out of band. Read the LIVE `charges` in preference to any directory listing, and pass what the listing claimed as `expect` to have the disagreement reported. IMPORTANT: 'status':'ok' is NOT an endorsement -- it only means a challenge was read and recorded. It cannot tell you whether the operator will deliver anything for your money. 'first_observation':true means there is no history at all, so an empty `drift` proves nothing. ALWAYS read `prior_criticals`: `drift` only compares against the last observation, so an endpoint that swapped its payee earlier shows an empty `drift` once that swap became the baseline -- a non-zero `prior_criticals` means it has changed where money goes before, and that is true no matter how clean today's look is. 'status':'unreachable' is not evidence of fraud and not evidence of health; do not pay on it either way. A null `price_usd` means the token's units are unknown here and the amount was NOT converted -- do not assume it is small. Costs $0.010 in USDC on Base, paid via the x402 protocol, or from a credit token — call credits_trial for free credit if you have neither.",
