# Gas regime



## OpenAPI

````yaml api-reference/openapi.yaml GET /gas
openapi: 3.1.0
info:
  title: AtlasYield 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:
