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.
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.
