  Curve's public REST API at api.curve.finance is operated on a fair-use basis without published
  per-key limits. Empirically responses are cached at the edge and consumers should respect a
  soft limit of around 60 requests per minute per IP.
notes: Curve does not publish a contractual rate limit; figures are best-effort.

    limit: 60
    notes: Soft fair-use; cache aggressively because most endpoints recompute on a fixed cadence.
