  version: 1.0.0
  summary: Agent-ready REST API for Prezent's content-generation and template-conversion services.
  description: "The Prezent Platform API exposes Prezent's AutoGenerator, Template Converter,\nAudiences, Themes, and File-upload services as a uniform JSON HTTP API.\n\nThis contract describes the **target agent-ready shape** of the API: every\ndocumented endpoint returns a uniform success envelope `{ \"success\": true,\n\"data\": { ... } }` or a uniform error envelope `{ \"success\": false,\n\"data\": null, \"error\": { \"code\": \"...\", \"message\": \"...\", \"details\": { ... } } }`.\nError codes are drawn from a stable catalog (see `ErrorCode`). The contract\nis additive: handlers may continue to emit legacy keys alongside the\ndocumented ones for backwards compatibility, so schemas explicitly allow\nadditional properties at the envelope and data levels.\n\nSeveral endpoints kick off long-running background work and return a\n`callback_id` that the client polls against a corresponding status\nendpoint. The canonical async polling endpoint for the Template Converter\nfamily is **`GET /api/v2/template-converter/status/{callback_id}`** which\nuses strict HTTP-status mapping (200 only on workflow success, 4xx/5xx on\nworkflow failure). The v1 polling endpoint at\n`/api/v1/template-converter/status/{callbackId}` (and its REST alias\n`GET /api/v1/template-conversions/{callback_id}`) continues to be served\nwith legacy semantics (HTTP 200 with `status` field) and is intentionally\nomitted from this documentation.\n\n**REST resource aliases (v1.1).** AutoGenerator and Template Converter\nendpoints are documented here under their REST-resource path names\n(`/api/v1/autogenerations`, `/api/v1/template-conversions`). The legacy\nRPC-style paths under `/api/v1/autogenerator/*` and\n`/api/v1/template-converter/*` continue to be served indefinitely; they\nreturn a `Deprecation: true` header pointing to the successor alias.\n\n**Conventions that apply to every endpoint** (full reference in the\ncompanion guides on this documentation site):\n\n- **Auth:** API key as a Bearer token — `Authorization: Bearer <key>`.\n  Each key is scoped to an allow-list of endpoint paths; an out-of-scope\n  call returns `404 ENDPOINT_NOT_FOUND`.\n- **Rate limits:** gateway throttle 10 req/s sustained, 5 burst,\n  1,000 req/day per key; per-company per-category 60-second sliding\n  windows; annual quotas (50,000 slide generations/yr, 1,000,000\n  downloads/yr). Limit breaches return `429` with `error.code`\n  `TOO_MANY_REQUESTS` (gateway), `RATE_LIMIT_EXCEEDED` (per-category),\n  or `USAGE_LIMIT_EXCEEDED` (annual).\n- **Errors:** every error uses the `{ success:false, data:null, error:{\n  code, message, details } }` envelope with stable, documented `code`\n  values.\n- **Idempotency & pagination:** mutating requests accept an\n  `Idempotency-Key`; list endpoints accept opt-in `limit`/`cursor`\n  paging.\n\n**Building with an AI agent?** Prezent ships a first-class Model Context\nProtocol (MCP) server. The hosted endpoint is\n`https://mcp.myprezent.com/mcp` (OAuth 2.1, works with Claude.ai Custom\nConnectors); a local stdio server is published on PyPI as\n`prezent-mcp-server` and plugs into Claude Desktop, Cursor, Cline,\nContinue, and Zed. The MCP tools wrap the same REST endpoints\ndescribed here.\n\n**Official SDKs.** Typed REST clients are published for Python and\nTypeScript (`prezent-sdk`) — generated from and versioned against this\nspec. For other languages, generate a client from this document.\n\n**Out of scope of this document:** SCIM endpoints under `/api/v1/scim/*`.\nThose endpoints conform to RFC 7644 (SCIM 2.0) and follow a different\nenvelope (`schemas`, `Resources`, `totalResults`, etc.). They are\ndocumented separately at /docs/scim-user-management.\n"
  x-out-of-scope-note: 'SCIM endpoints (`/api/v1/scim/*`) are NOT included in this spec. They

    follow RFC 7644 (SCIM 2.0) and are documented in a separate document at

    /docs/scim-user-management.
