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.

OVER TIME

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/blockrun/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).

PRICE (captured 402, USD)

Median across 10 endpoints. Use the selector to isolate one.

SUB-SCORES (uptime + x402 compliance)

VOLUME (on-chain settlement, USD)

On-chain traction has not been assessed for this service yet.

DISTINCT BUYERS
