description: SendPulse publishes explicit REST request quotas tiered by pricing plan, in requests per minute and
  requests per day, on its API documentation page. Exceeding the quota returns HTTP 429. A separate hard ceiling
  of 10 requests per second is enforced and surfaces as proprietary error code 2020202020. OAuth2 access tokens
  are additionally short-lived (3600s).

responseCodes:
  throttled: 429
headers:
  published: false
  note: SendPulse documents NO rate-limit response headers — no X-RateLimit-*, no RateLimit-*, no Retry-After. An
    agent cannot read remaining quota from a response and must infer exhaustion from the 429 status or error code
    2020202020. This is the single biggest runtime-semantics gap in the API.
