ASSESSMENT

updated 6h ago

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

compliance A (11/11)

11 of 11 x402 conformance checks pass. Full checklist below.

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.

traction $106.63 30d · 23 buyers

volume 30d: $106.63
buyers 30d: 23
settlements 30d: 1,464
last settlement: 2026-07-19
top buyer share: 56% of 30d volume
trend 7d vs 30d: 0.59x the 30d daily rate
networks: eip155:8453

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts share the 24h window selected here. Every series is also served as JSON at /api/v1/services/mycelia-signal/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).
