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.

ENDPOINTS
| METHOD | PATH | DESCRIPTION | PRICE | NETWORK | ASSET | 402 CHANNEL |
|---|---|---|---|---|---|---|
| GET | /{chain}/address/{address}/balances_nft/ | NFT balances | $0.0001 | Base Sepolia | USDC | header |
| GET | /{chain}/address/{address}/balances_v2/ | Token balances | $0.0001 | Base Sepolia | USDC | header |
REQUEST / RESPONSE EXAMPLE
An unpaid request to GET /{chain}/address/{address}/balances_nft/ 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 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/goldrush/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.
Median across 2 endpoints. Use the selector to isolate one.

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.
