OVER TIME
All charts share the 24h 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.
