Find creators to work with

GET /v1/discover/creators

Search Meta creator discovery for people a brand could partner with. A Facebook Page searches Facebook Creator Discovery directly. An Instagram account connected through Facebook searches Instagram Creator Marketplace. Entries marked `sample: true` are test data, not real outreach targets.

Request

Authenticate with a bearer API key. Agents calling over MCP authorise with OAuth instead and never handle the key.

curl -X GET https://api.postlake.dev/v1/discover/creators \
  -H "Authorization: Bearer $POSTLAKE_API_KEY"

Example

{
  "items": [
    {
      "id": "…",
      "handle": "…",
      "displayName": "…",
      "avatarUrl": "…",
      "bio": "…",
      "categories": "…",
      "country": "…",
      "portfolioUrl": "…"
    }
  ],
  "cursor": "…",
  "platform": "…"
}

Paging

Pass limit (1 to 100, default 50) and the cursor returned by the previous page. A response with a null cursor is the last page. Every list endpoint pages the same way, so one helper covers all of them.

Limits

Reads are limited to 600 requests a minute per account. Every response carries X-RateLimit-Remaining and X-RateLimit-Reset, and a 429 includes Retry-After so a client can back off without guessing. Reads of network data (comments, followers, conversations) are metered in credits; reads of your own PostLake state are not.

Calling this from an agent

This operation is part of the REST surface. Agents working over the hosted MCP server reach the same product through tools instead, and authorise with OAuth so your API key is never pasted into a chat. See the MCP server.

Errors

Every failure uses one shape: a stable type, a granular code, the field at fault in param, and a plain-language fix. An agent can act on it without a person reading the message. See Errors and retries.

Check the result before retrying a write. Only operations that explicitly support idempotency can safely replay an Idempotency-Key.

Common questions

How often can I call this?

Reads are rate limited per account and every response carries X-RateLimit-Remaining and X-RateLimit-Reset. On a 429 the Retry-After header tells you how long to wait.

What happens when it fails?

You get one error shape: a stable type, a granular code you can branch on, the offending field in param, and a fix written so an agent can correct itself rather than stop. Full list on Errors and retries.
