    "description": "The Method API enables you to retrieve financial data, create payments, and manage\nentities and accounts programmatically. This specification covers the public API\nsurface for version `2025-12-01`.\n\n## Authentication\n\nMost API requests require a Bearer token in the `Authorization` header.\nUse your secret key (`sk_...`) for server-side requests and public key (`pk_...`)\nfor client-side Element requests. Public Message-Level Encryption key discovery\nendpoints are documented separately and do not require authentication.\n\n## Versioning\n\nThe API version is selected via the `Method-Version` header. This spec targets\nversion `2025-12-01`. The SDK sets this header automatically.\n\n## Response Envelope\n\nMost JSON responses are wrapped in a standard envelope:\n\n```json\n{\n  \"success\": true,\n  \"data\": { ... },\n  \"message\": null\n}\n```\n\nThe `/.well-known/jwks.json` endpoint is an exception and returns a bare JWK set.\n\n## Pagination\n\nList endpoints return pagination metadata in response headers:\n`Pagination-Page`, `Pagination-Page-Count`, `Pagination-Page-Limit`,\n`Pagination-Total-Count`, `Pagination-Page-Cursor-Prev`, `Pagination-Page-Cursor-Next`.\n\n## Expandable Fields\n\nCertain resource fields can be expanded from IDs to full objects using the\n`expand` query parameter. Maximum nesting depth is 4 levels.\n\n\nContact Support:\n Name: Method Financial\n Email: team@methodfi.com",
