2s.io/api/person/cross-registry
As of 2026-08-15, 2s.io/api/person/cross-registry on Base responded to 93.3% of 30 reliability checks over the past 30 days, often enough to use but with outages frequent enough to plan around. Responses came back sluggish at 670 ms average from a single EU vantage point (so this includes network distance to the endpoint) and it has held its advertised price steady at $0.0180. Its x402-trust grade is A (score 82.8 from a moderate sample, tracked for 64 days), so it currently looks safe to use.
Sweep a person's name across five US public registries in one call: FINRA securities brokers, federal-court attorneys (CourtListener), federal inmates (BOP), Texas trade licenses (TDLR), and Texas real-estate licenses (TREC). Returns one block per registry with found/error status, match count, and the matching records — name-matched CANDIDATES, deliberately not merged into one identity (same name does not mean same person; verify with each registry's identifier before acting). Due-diligence, KYC screening triage, and background-research staple. Each registry is also a standalone endpoint (/api(Provider-supplied: an unverified claim, not checked by us. The trust grade above is our independent measurement.)
POST /v1/x402-trust or the x402_trust_score MCP tool.Latency is measured from a single EU vantage point; includes network round-trip distance to the endpoint; a geographically distant endpoint reads slower even when its server is fast, so it is only lightly weighted in the score.
10 better-scored (some cheaper) endpoints serving a semantically similar purpose exist.
We don't reveal which ones here. The ranked list (resource URLs, exact scores, prices & similarity, etc...) is one paid call away. Purchase it right here with a browser wallet, no code required:
A wallet payment page opens first; approve the USDC payment and the ranked JSON list loads right in your browser. Agents use the x402_find_alternatives MCP tool or POST /v1/similar directly.

- ✓Live probe at decision time:
We re-check the endpoint the moment you ask (timestamped) and compute the score from all scores up until this moment, instead of this cached snapshot that may be up to 24h old. - ✓Confidence band, full component breakdown & structured risk flags:
Exactly why the score is what it is, machine-readable. - ✓On-chain settlement proof:
Real USDC volume & distinct-payer count for the payTo wallet: is anyone actually paying it? - ✓90-day raw history:
Every listing/price/payTo change and probe result (viaPOST /v1/x402-history), up to 90 days back. - ✓The ranked better-scored alternatives:
The resource URLs, scores & prices we don't reveal above (viaPOST /v1/similar), if there are better alternatives available. - ✓Change & liveness alerts:
Get notified on payTo/price changes, spec regressions or downtime (viaPOST /v1/watch-endpoint-30d). Connect up to 10 Discord / Slack webhooks or poll regularly with bearer auth. Increases probe-density to every 5 minutes instead of the usual 30 for the watched endpoint.
... Simply give your agents the tools to do all of that for you, with a simple command
