OpenAPI Specification

openapi: 3.2.0
info:
  title: AtlasYield Catalog API
  version: '1.0'
  description: 'Read-only access to the Atlas Score Index: neutral 16-factor vault scores across four pillars — Yield, Safety, Liquidity, Sustainability — plus the tracked vault catalog and the Atlas Engine, which turns those scores into a risk-adjusted allocation. Research and information, not investment advice.

    Every endpoint in this spec is public and keyless, limited to 60 requests per minute per IP. An optional partner key sent in the `x-api-key` header moves the caller to its own bucket of 100 requests per minute and unlocks two endpoints that are not part of this spec (every vault''s factor breakdown in one call, and score history). A key is never required: an unknown or retired key sent to a public endpoint is ignored, and only the two partner endpoints reject it, with a 401. How to get one: https://docs.atlasyield.club/partner-access'
