Efficiently retrieve data for up to 100 profiles at once. **Response includes:** - `found`: Array of profiles that exist in our database - `not_found`: Array of profiles that weren't found (consider live scraping these) Also callable as the `lookup_profiles` MCP tool — see [the MCP server guide](/guides/mcp-server) for setup. **Pricing**: 0.1 credits per profile ($0.001) ## OpenAPI ````yaml https://app.stainless.com/api/spec/documented/influship-api/openapi.documented.yml post /v1/profiles/lookup openapi: 3.1.0 info: title: Influship API version: 1.0.0 description: > Public API for creator search, profile lookup, and campaign-fit analysis. ## Authentication Send your API key in the `X-API-Key` header on every authenticated request. ```bash curl -H "X-API-Key: your_api_key" https://api.influship.com/v1/creators/autocomplete?q=fitness ``` ## Billing and Rate Limits The API uses credit-based billing and credit-based rate limits. - every endpoint has a credit cost - successful responses include `X-Credits-Charged` and `X-Credits-Features` - rate limits are enforced with per-minute and per-hour credit budgets - rate limit state is returned in the `RateLimit-*` headers ## Pagination List endpoints use cursor pagination. - send `limit` to control page size - use `next_cursor` from the response to fetch the next page - stop when `has_more` is `false` Search has one special rule: - `POST /v1/search` creates a persisted search session - `GET /v1/search/{id}` paginates that session for free - free pagination is capped by the original search `limit` ## Errors Errors use a consistent shape: ```json { "error": { "code": "rate_limit_exceeded", "message": "Rate limit exceeded (per minute)" } } ``` See each operation for exact request and response schemas. contact: name: Influship Support email: support@influship.com license: name: Proprietary url: https://influship.com/terms servers: - url: https://api.influship.com description: Production security: - ApiKeyAuth: [] tags: - name: Health description: API health and status endpoints - name: Creators description: >- Retrieve creator profiles and discover new creators through search, autocomplete, and lookalike matching.
