  types:
  - apiKey
  api_key_in:
  - header
  oauth2_flows: []
  note: >-
    No OAuth flow, no wallet signature per request, no session tokens on the Router. Two
    prefixed bearer credentials do everything. A separate wallet JWT (sign-in session at
    pc.0g.ai) is required for management-key administration and is not issuable as a key.
    The 0G Compute "Direct" path is different: it has no API key at all — the caller's wallet
    signs each request against a per-provider sub-account.

- name: ApiKeyAuth
  type: apiKey

  parameter: Authorization
  format: Bearer sk-...
  prefix: sk-
  purpose: >-
    Call inference endpoints (/v1/chat/completions, /v1/messages, /v1/images/*,
    /v1/audio/transcriptions, /v1/videos, /v1/routing/preview). Billed against the account's
    on-chain deposit.

  issuance: >-
    Dashboard > API Keys. The full secret is shown once on creation; the dashboard stores only a
    hash. Keys are labelled, listed with created-at and last-used, and revocable instantly — a
    revoked key returns 401 api_key_revoked on its next call.

  in: header
  parameter: Authorization

  prefix: mk-
  purpose: >-
    Administer the account — read balance/usage/history and list, create, edit or revoke API
    keys. Not billed. Cannot call inference.
  description: >-
    Management key for account read and API key management. Capabilities are scope-limited per
    key (account:read, keys:read, keys:create, keys:manage). Format: "Bearer mk-..."
  issued_at: https://pc.0g.ai
  issuance: Settings > Management Keys. Each key carries an explicit scope allowlist. Keys do not expire.

  audit_fields:
  - last_used_at
  - last_source_ip
  audit_note: >-
    Updated on every successful mk- request, coalesced to at most one write per key per 60s.
    IPv4-mapped IPv6 addresses are normalized to dotted-quad. sk- keys do not record these —
    their audit signal is usage/billing.

  required: wallet JWT (sign-in session) only
  rationale: >-
    A leaked mk- cannot mint replacements for itself. keys:manage and keys:create are also
    deliberately split so an audit integration can revoke a compromised key without being able
    to issue a new one.
unauthenticated_endpoints:
- GET /v1/models
- GET /v1/providers
- GET /v1/service-types
guidance:
- Never ship either key to a browser — proxy client requests through your own backend.
- One key per deployment so a revocation is scoped to one service.
- Least privilege for mk-; rotate by issuing a replacement and revoking the old key.
breaking_change:
  observed: '2026-08-05'
  detail: >-
    sk- keys no longer have access to /v1/account/* (balance, usage, history). Existing
    dashboard/billing code must move to an mk- key with the account:read scope.
