  Measurabl Core API rate limits, published in the 2023-12-18 release note that raised every
  ceiling. Limits are enforced PER ENDPOINT over a rolling 5-minute window and are split by HTTP
  method class, with a higher write allowance for the meter endpoints that carry bulk utility
  ingestion. Measurabl publishes no rate-limit response headers and no per-tier table.

batch_caps:
  note: >-
    Separate from request-rate limiting, the ESGx Buildings API rejects oversized batch payloads
    with 413 - "too many estimates in request", "too many certification lookups in request",
    "too many ordinance lookups in request". The numeric cap is not published in the spec.
