Security and provenance for an open-source package, composed live from three authoritative sources in one call. Pass ecosystem (npm, pypi, go, maven, cargo, nuget) + name (+ optional version; defaults to latest). Returns: known vulnerabilities from OSV (osv.dev — aggregates GitHub Security Advisories, PyPA, RustSec, Go vuln DB, etc.) each with its id, CVE aliases, summary, severity, and references; the resolved license and deprecation status (deps.dev); and the source repo's OpenSSF Scorecard health score (overall + per-check) plus stars/forks/open-issues. All live — newly-disclosed advisories appear within hours. Distinct from registry.npm-lookup / pypi-lookup (metadata only): this answers "is this dependency safe to add, what license does it carry, and how well-maintained is it."
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Hand this page to an agent
Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 22 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service 2s and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=2s' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://2s.io/api/security/package, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
