Authenticate with a secret key from Integrations → API: `Authorization: Bearer dk_live_…`. Keys carry scopes; personal data needs `contacts:read`. Rate limits are per key per minute, the same on every plan: 600; heavy calls (exports, crawls, model work) have a smaller budget (30). Plans from before credits keep theirs. An Agency's client workspaces have the Agency's. Every response carries RateLimit-* headers. The chat API is on every plan: 2,500 conversations a month per workspace. Lists are cursor-paginated (`limit`, `starting_after`, `next_cursor`). Writes accept `Idempotency-Key`. Errors are RFC 9457 problem documents with a stable `code` and a `request_id`. contact: name: Darwin url: https://docs.meetdarwin.ai/api-reference/introduction servers: - url: https://api.meetdarwin.ai/v1 security: - bearer: [] tags: - name: Workspace - name: Conversations - name: Contacts - name: Meetings - name: Outcomes - name: Personal links - name: Analytics - name: Events - name: Webhooks - name: Knowledge - name: Agent - name: Experiments - name: Privacy - name: Chat paths: /page_openings/current: get: tags: - Experiments summary: What one page shows now, and why description: Requires the `experiments:read` scope. operationId: getCurrentOpening parameters: - name: path in: query required: false description: The page, such as /pricing. schema: type: string responses: '200': description: OK content: application/json: schema: $ref: '#/components/schemas/CurrentOpening' '400': description: Invalid request (`invalid_request`, `unsupported_version`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '401': description: >- Missing or invalid key (`authentication_required`, `invalid_api_key`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '402': description: >- The workspace must add a card before the API can be used (`payment_required`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '403': description: >- The key lacks the scope (`insufficient_scope`), the feature is off (`feature_disabled`), or the workspace's plan doesn't include it (`plan_required`, with `required_plan`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '404': description: No such object in this workspace (`not_found`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '409': description: >- Conflicts with the current state (`conflict`, `idempotency_key_in_use`), or the change would leave a live agent with no calendar or live form (`goal_required`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '422': description: Refused by a rule (`unprocessable`, `idempotency_key_reused`). content: application/problem+json: schema: $ref: '#/components/schemas/Problem' '429': description: >- Rate limited (`rate_limited`) or a monthly allowance used (`quota_exceeded`); see Retry-After. content: application/problem+json: schema: $ref: '#/components/schemas/Problem' components: schemas: CurrentOpening: type: object properties: object: type: string const: current_opening page: type: string source: type: string enum: - test - page - site description: >- test: a running test shows one of its openings to each visitor; this is the current one it compares against. page: the page's own opening. site: the site's opening. headline: type: string buttons: type: array items: type: object properties: label: type: string message: type: string locked: type: boolean required: - label - message - locked page_opening: anyOf: - type: object properties: id: type: string page: type: string required: - id - page - type: 'null' experiment: anyOf: - type: object properties: id: type: string name: type: string openings: type: integer minimum: -9007199254740991 maximum: 9007199254740991 required: - id - name - openings - type: 'null' required: - object - page - source - headline - buttons - page_opening - experiment Problem: type: object properties: type: type: string example: https://docs.meetdarwin.ai/api-reference/errors#insufficient_scope title: type: string status: type: integer minimum: -9007199254740991 maximum: 9007199254740991 code: type: string example: insufficient_scope detail: type: string param: type: string required_plan: description: >- With `plan_required`: the plan that unlocks what was refused.
