name: Sharethrough Rate Limits
description: >-
  Sharethrough publishes no rate limits for either API surface, and neither surface returns a
  rate-limit header. This file records that absence with the probes that establish it, rather
  than asserting numbers nobody published.

rateLimits:
  - name: Publisher Reporting API
    endpoint: https://publisher-api.sharethrough.com/v2/programmatic
    scope: per-token (assumed; not stated)
    window: null
    limit: null
    burst: null
    headers: none
    authentication: 'Bearer token (Authorization: Bearer <AUTH_TOKEN>)'
    outputFormats:
      - CSV
      - JSON
    reportTypes:
      - programmatic
    note: >-
      No explicit rate limit is published. The reference that would have carried one is gated:
      the support section returns 401 anonymously and the reference article returns 404. Usage
      is batch reporting rather than high-frequency polling. The v1 direct-sell report type is
      not routed under /v2.
  - name: Header Bidding / OpenRTB Bidding Endpoint
    endpoint: 'https://btlr.sharethrough.com/universal/v1?supply_id=<supply_id>'
    scope: per-bid-request
    window: per auction
    limit: null
    burst: null
    headers: none
    effective_constraint: >-
      The binding constraint is the auction timeout the publisher configures and passes as
      OpenRTB tmax, not a published request quota.

notes:
  - >-
    limit_count is 0 because Sharethrough documents zero limits — an honest zero, recorded
    rather than omitted.
  - >-
    The absence of rate-limit response headers is the more consequential finding for an agent
    or client library: there is no runtime signal to back off against, only whatever the API
    does when it decides it has had enough.
  - >-
    For integration-specific thresholds a publisher must ask their Sharethrough/Equativ
    account manager; there is no public channel for it.
