model: |
  A single free API key, passed as the api_key query parameter on every APIv2 request. EIA
  states explicitly that the key must appear in the URL and will NOT be detected in HTTP
  headers, even though other query parameters MAY be sent in the request body
  (application/x-www-form-urlencoded on GET, or a JSON DataParams body on the POST form of a
  /data route) to work around URL length limits. There is no OAuth, no OIDC, no bearer token,
  no mutual TLS, no scopes and no per-resource authorization - every key sees the same public
  statistical data.

  fields:
  - First Name (required)
  - Last Name (required)

  delivery: Emailed automatically to the address supplied; no human review, no accreditation,
    no licence to sign.
  sender: developer@eia.gov - EIA asks that this address be whitelisted in spam filters.
  recovery: '"Forgot API Key" flow linked from https://www.eia.gov/opendata/'
  cost: free
unauthenticated_surface:
  bulk_download: https://api.eia.gov/bulk/manifest.txt and every /bulk/*.zip dataset are
    retrievable with NO key at all.
  spec_download: https://www.eia.gov/opendata/eia-api-swagger.zip is anonymous.
  console: https://www.eia.gov/opendata/browser/ is anonymous.
enforcement:
  missing_key: HTTP 403 with {"error":{"code":"API_KEY_MISSING","message":"No api_key was
    supplied.  Please register for one at https://www.eia.gov/opendata/register.php"}} -
    verified live 2026-07-27.
  invalid_key: HTTP 403 with {"error":{"code":"API_KEY_INVALID", ...}} - verified live
    2026-07-27 with a 40-character bogus key.
  throttled_key: The key is automatically and temporarily suspended above the published
    thresholds and automatically reactivated. See rate-limits/eia-rate-limits.yml.
  embeds: The chart-widget embed now also requires a key; unkeyed embeds render
    API_KEY_MISSING.
transport:
  https_only: true
  note: APIv2 is HTTPS-only. APIv1 also served plain http; EIA flagged that http would "end
    soon" as part of the v2 migration.
key_handling_risk: Because the key travels in the query string it is exposed in browser
  history, referrer headers, proxy logs and server access logs, and the documented embed
  pattern places a live key in public page HTML. There is no key rotation UI - recovery is via
  the Forgot API Key flow.
