Read-only access to the Atlas Score Index: neutral 16-factor vault scores across four pillars — Yield, Safety, Liquidity, Sustainability. Public, no key, JSON out. A stranger should be able to integrate in under 30 minutes. The machine-readable OpenAPI 3.1 document is at docs.atlasyield.club/api-reference/openapi.yaml.

​
Authentication

None. The API is public and read only. No key, no signup, no tiers.
/scores and /catalog serve whatever is currently cached. /portfolio fails closed: an allocation is an active recommendation, so it returns 503 rather than allocating on stale scoring data. Treat a 503 as “ask again shortly”, not as an outage.

​
Rate limits

60 requests / minute per IP. Exceeding it returns 429 with standard RateLimit-* headers. The dataset refreshes on a scoring cadence of hours, not seconds — cache responses and poll sparingly.

​
Versioning

Everything lives under the /v1 prefix. Breaking changes ship under a new prefix; /v1 stays stable. Every score row also carries scorerVersion so you can pin to a scoring engine revision.

​
Disclaimer

Atlas Scores are research and information, not investment advice. The same line ships on every response — as a disclaimer field and an X-Atlas-Disclaimer header. Scores are neutral, model-driven signals; you are responsible for your own listing and allocation decisions. See Limitations.

​
Coverage requests

Nothing to request access to. If there is a protocol or chain you need scored that we do not cover yet, email admin@atlasyield.club or DM @atlasyieldclub on X. Tell us the surface you are building and the sources you route to. You can tell us what to cover. You cannot tell us what it scores.
