Filter by `from`/`to` (ISO-8601, inclusive on `createdAt`); choose the bucket size with `granularity` (day/week/month). ## OpenAPI ````yaml GET /router/payments/summary openapi: 3.1.0 info: title: Nevermined API description: >- API for managing AI agents, payment plans, and x402 payments in the Nevermined ecosystem. ## Prerequisites You need a Nevermined API Key to authenticate.

Framework-level `BCK.HTTP.*` codes (e.g. `BCK.HTTP.400` request validation, `BCK.HTTP.429` throttling) may also appear — see the base `code` field. example: BCK.ROUTER.0003 httpStatus: type: number description: HTTP status code example: 500 message: type: string description: Error message for Router operations. example: delegation budget exceeded, expired, or inactive examples: - >- delegationId is required — create one via POST /api/v1/delegation/create - 'no fundable option; offered: [...]' - >- upstream pay-to address is not in this delegation's allowed recipients - delegation budget exceeded, expired, or inactive - payment already settled with a different txHash details: type: string description: >- Throw-site detail string supplementing the canonical message.

Present only on the OAuth device-polling responses from `POST /oauth/token` (`authorization_pending`, `slow_down`, `expired_token`, `access_denied`), so a standards-compliant OAuth/device client can branch on it directly instead of on the Nevermined `code`. Absent on every other error. example: authorization_pending hint: type: string description: >- Actionable remediation hint, sourced from the catalogue or supplied at the throw site.

Absent when the catalogue does not assert either way. example: true correlationId: type: string description: >- Request-scoped correlation id stamped by the global filter.
