Re-evaluate

Sub-claim "x402 services must register with the Circle service registry": 0% covered — No gathered source mentions registration with a Circle service registry.

Re-evaluate

Sub-claim "Other agents must be able to query the registry to discover …": 0% covered — No gathered source discusses querying a registry for discovery.

Re-evaluate

Sub-claim "The registry must maintain accurate and up-to-date informati…": 0% covered — No gathered source addresses registry maintenance or accuracy.

Re-evaluate

All three sub-claims have zero coverage. The remaining budget is 0.015, which can afford multiple low-cost sources. Recommended sources are those with relevant-sounding names (e.g., distributed systems, crypto news, blockchain blogs) that might cover service registries and discovery. Priority order: Distributed Systems Notes (0.003), then crypto news sources (0.002 each), then blogs (0.003-0.004). Total cost of recommended sources: 0.003+0.002+0.002+0.002+0.003+0.003+0.003+0.004+0.002 = 0.024, which exceeds budget. To stay within 0.015, select a subset: e.g., Distributed Systems Notes (0.003), Cointelegraph (0.002), Decrypt (0.002), CoinDesk (0.002), Simon Willison (0.003), Hugging Face (0.003) = 0.015 exactly. That covers 6 sources. If any of these provide relevant info, coverage may improve.
