Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

No settlement address is mapped for this service yet, so on-chain volume cannot be measured. Shown as unmeasured, not zero.

REQUEST / RESPONSE EXAMPLE
An unpaid request to POST /api/research returns HTTP 402 with the payment terms. Settle onchain via your facilitator, then retry with the X-Payment header.

] OVER TIME
All charts use the 7d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/resonant-glyph-research-synthesis/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.

Measured site and economics pillars from the assessment history, so the latest value shown elsewhere on this page reads as a point on a trend rather than a permanent state.
