Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) 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 could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
10 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

description: 'Free public REST API that returns whether a given crypto address is identified as sanctioned by OFAC, EU,
or UN sanctions authorities. No commercial licence required; widely embedded by wallets, dApps, and exchanges to block
sanctioned addresses at the perimeter. Requires a free API key supplied in the X-API-Key header - probed 2026-08-27, an
invalid key returns HTTP 401 {"message":"Invalid API Key"}. Chainalysis ships the same sanctions data in a second, separate
form: a permissionless on-chain oracle smart contract exposing isSanctioned(address), deployed across Ethereum, Polygon,
BNB Smart Chain, Avalanche, Optimism, Arbitrum, Fantom, Celo, Blast, and Base, which needs no API key at all. The go.chainalysis.com
document below covers the ORACLE; the REST reference is inside the gated developer portal.'
