54ch10

54ch10 serves pre-interact risk briefs for wallet addresses, tokens and URLs — phishing, scam, honeypot and URL-reputation heuristics an agent can call BEFORE it signs, approves, bridges or opens a dapp URL. A brief returns a 0–100 score where higher is more concerning, a band, flags, a summary and the sources behind it, so a caller can gate its next tool call on policy: refuse on critical, require human confirmation on elevated. The provider describes it as analytics-only and explicitly not financial, legal or investment advice. Four operations over OpenAPI 3.0, bearer authenticated, with a free tier and an x402 machine-payment surface on Base.

54ch10 publishes 3 APIs on the APIs.io network: Brief API, Health API, and .well Known API. Tagged areas include wallet-risk, Phishing, Scam Detection, url reputation, and x402.

54ch10’s developer surface includes documentation and 2 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/54ch10: open an issue to ask a question, or submit a pull request to add artifacts.

  note: 'Submitted via apis.io/add on 2026-08-24 and auto-published by the gate at rating 37. The submitted APIs.json at https://54ch10.uk/apis.json
    returns 404 against a control that also 404s with an identical 531-byte JSON body, so the 404 is real — a bad pointer
    in the submission, not an absent surface. There is no llms.txt either. What IS served was fetched and confirmed: OpenAPI
    3.0.3 at /openapi.json (4 paths, bearer auth, though zero component schemas), an AGENT.md written directly at agents rather
    than at humans, and an x402 discovery document at /.well-known/x402 declaring x402Version 2 on the Base network with the
    payai facilitator. /health returns 200 JSON. Both brief endpoints return 400 JSON on a malformed call, which is validation
    rather than a stub. The AGENT.md is the interesting artifact: it tells a calling agent the order of operations — resolve
    the target, GET /v1/brief, then gate the next tool call on the returned band — and tells operators to log cached_at and
    sources[].status so they can tell a stub signal from a live one. It is kept here in full. Note the brand: the provider
    states it is "54ch10", NOT "SACHIO".'
