OpenAPI Specification

openapi: 3.2.0
info:
  title: ASPERN Account API
  version: '0.2'
  summary: The independent record of what machine-managed capital actually does.
  x-performance:
    simpleReads:
      p95Ms: 500
      meaning: A list or a lookup, warm.
    heavyAnalytics:
      p95Ms: 2000
      meaning: Correlation, the index, stress and cascade, warm.
    coldPath:
      meaning: 'The first call after a cache expires. Not covered by the figures above. The deploy and a five-minute timer warm the heavy free endpoints, so a caller should rarely meet one there. `/v1/correlation` is the exception and is the slowest: it needs a capability, so the warmer cannot reach past the gate without holding a key, and putting a credential in the web process to solve a latency problem is a trade we have not made. Expect several seconds on the first call after an expiry.'
    timeoutSeconds: 60
    maxWindowDays: 400
  description: 'Ratings are free. The data, the analytics and the certification are not.


    Every response states what it cannot see. Coverage, sample size and the mechanism behind a figure travel with the figure rather than sitting in documentation, because a number read without them is the failure this platform exists to prevent.'
  x-aspern-environment: production
  x-aspern-build: 20261101T2237Z-27da4c8c29
  x-contract-hash: 6c89cbaf2e2c50bd2b65bddf516e17b855704d01e471a6c06c19354fedc7367d
  x-stability:
    policy: additive-within-major
    promise: 'Within /v1 the contract only grows: new routes, optional parameters, fields and warning codes. Routes and fields are never removed or renamed, and no type, unit or status meaning changes.'
    deprecation:
      marker: 'x-lifecycle: deprecated, with the replacement named'
      minimumDays: 180
      removal: only in a new major version; /v1 keeps answering through the deprecation period
    verification: checked daily against the approved operation inventory; every change of x-contract-hash is recorded
