Discovery endpoints are public; audience management accepts either Bearer JWT or X-API-Key auth. servers: - url: https://api.aws53.cloud description: Production security: [] tags: - name: Topic Discovery description: Browse, search, and analyze available intent topics - name: Site Analysis description: Analyze a website URL to find matching intent topics - name: Site Topics description: Recent organization site-topic analyses - name: Audience Builder description: >- Curated filters, preview, saved audiences, runs, exports, webhooks, and managed destinations paths: /v1/intent/topics: get: tags: - Topic Discovery summary: Browse all available intent topics description: >- Returns the available intent-topic catalog with optional type, industry, category, and text filters. Results are ordered by topic name with no guaranteed secondary ordering for equal names. The whole matching catalog is returned without pagination. Catalog results are cached for 24 hours, with stale fallback if refresh fails. Industry and category filters use case-insensitive exact matching; q uses a case-insensitive topic-name substring. This public operation allows 2 requests per source IP per 60 seconds without valid authentication, or 200 with a valid bearer token or active organization API key. operationId: browseAllAvailableIntentTopics parameters: - schema: type: string enum: - b2b - b2c - both description: >- Restrict topics to the selected classification; both matches that literal classification. example: b2b required: false description: >- Restrict topics to the selected classification; both matches that literal classification. name: type in: query example: b2b - schema: type: string maxLength: 100 description: Filter by industry name. example: Technology required: false description: Filter by industry name. name: industry in: query example: Technology - schema: type: string maxLength: 100 description: Case-insensitive exact category name. example: Cloud Computing required: false description: Case-insensitive exact category name. name: category in: query example: Cloud Computing - schema: type: string maxLength: 100 description: Case-insensitive substring of the topic name. example: cloud required: false description: Case-insensitive substring of the topic name. name: q in: query example: cloud responses: '200': description: Topic catalog headers: RateLimit-Limit: description: Maximum requests allowed per source IP in 60 seconds. schema: type: integer example: 2 RateLimit-Remaining: description: Requests remaining in the current source-IP window. schema: type: integer example: 0 RateLimit-Reset: description: Seconds until the current source-IP window resets. schema: type: integer example: 60 content: application/json: schema: $ref: '#/components/schemas/TopicInventoryResponse' examples: populated: value: data: - topicId: 1001 topicName: Example cloud platform type: b2b industry: Technology category: Cloud Computing meta: count: 1 total: 3 filters: type: b2b industry: null category: null q: cloud empty: value: data: [] meta: count: 0 total: 3 filters: type: null industry: null category: null q: unmatched-example-topic '429': description: >- Source-IP allowance exceeded: 2 requests per 60 seconds without valid authentication, or 200 with a valid bearer token or active organization API key. headers: RateLimit-Limit: description: Maximum requests allowed per source IP in 60 seconds. schema: type: integer example: 2 RateLimit-Remaining: description: Requests remaining in the current source-IP window. schema: type: integer example: 0 RateLimit-Reset: description: Seconds until the current source-IP window resets. schema: type: integer example: 60 Retry-After: description: Seconds to wait before retrying. schema: type: integer example: 60 content: application/json: schema: type: object properties: error: type: object properties: code: type: string message: type: string details: {} required: - code - message meta: type: object properties: timestamp: type: string request_id: type: string required: - timestamp - request_id required: - error - meta example: error: code: RATE_LIMIT_EXCEEDED message: Too many requests, please try again later meta: timestamp: '2026-01-15T12:00:00.000Z' request_id: example-request security: [] components: schemas: TopicInventoryResponse: type: object properties: data: type: array items: type: object properties: topicId: type: number topicName: type: string type: type: string industry: type: string category: type: string required: - topicId - topicName - type - industry - category meta: type: object properties: count: type: number description: Number of topics matching the supplied filters. total: type: number description: Number of topics in the catalog before filters. filters: type: object properties: type: type: - string - 'null' industry: type: - string - 'null' category: type: - string - 'null' q: type: - string - 'null' required: - type - industry - category - q required: - count - total - filters required: - data - meta ````
