Listed in a public agent registry. The name is the registry's label, not ours. Not reviewed by a person. See all 80 endpoints from onesource.io. The URL contains placeholders (such as :address) that callers fill in.

Checked hourly. Hourly: 100 or more distinct payers in the last 30 days, as reported by the registry.

In the capability tree: Financial and economic data / Crypto and on-chain data (primary). Placed by three checks by a small AI model: placed, found blind from its tasks, and verified against its own text (placement-ai/3, tree/3) on 2026-10-18. Wrong place? Tell us.

In the directory: meets our listing criteria (listing-criteria/3): ✓ says what it does; ✓ its latest check passed; ✓ at least 5 payers in 30 days (registry figure).

Recent probes

What this evidence does not show

• A passing probe means the endpoint answered an unpaid request with a valid payment request on a production network (x402 on a mainnet network, or MPP on Tempo mainnet). It does not show that a paid call succeeds or returns useful results.
• Payer and call counts are the registry's own figures, not our measurements.
• The registry's description is not republished.
• Limited evidence: monitored for 1 day (less than 30).
