  https://api.data.gov/signup/, https://api.data.gov/docs/developer-manual/ and
  https://open.gsa.gov/api/ — checked for any published price, tier or paid
  upgrade path across the GSA developer surface. Replaces the 2026-05-04
  scaffold, which invented "professional" and "enterprise" tiers.
description: >-
  GSA publishes no pricing of any kind for its APIs, and that is the finding,
  not a gap in our research. Every API in this record is a free public
  government service: you self-register an api.data.gov key (or a SAM.gov
  account key), you are metered, and there is no paid tier to buy. The
  documented escalation path for more capacity is an email to the owning agency,
  not a checkout.

    description: >-
      A single self-service api.data.gov key that works across every
      participating federal API, GSA's included. No card, no contract, no tier.
    included:
      - label: Requests
        metric: requests_per_hour
        limit: 1000
        note: See rate-limits/general-services-administration-rate-limits.yml; SAM.gov meters daily instead.
    overage: >-
      None. Exceeding the allowance returns HTTP 429 OVER_RATE_LIMIT and the key
      is temporarily blocked until the rolling window clears.

enterprise_contact_only: false
notes:
  - >-
    Some GSA data behind these APIs is access-controlled rather than priced —
    SAM.gov FOUO and CUI-Sensitive entity data requires a role and a system
    account, and the TMSS 2.0 Rate Query API requires a signed MOU with GSA FAS.
    Those are eligibility gates, not plans.
