curl https://api.unifapi.com/linkedin/search/posts?query= \ -H "Authorization: Bearer $UNIFAPI_KEY"
Parameters
- queryqueryrequired
- Keyword or phrase to search for in public LinkedIn posts.
- date_postedquery
- Optional filter for how recently matching posts were published.
- cursorquery
- Opaque pagination cursor from a previous response's `pagination.next_cursor`. Omit for the first page.
- The parameter for this LinkedIn operation. Use the URL-visible slug or id described in the docs.
This operation is part of the LinkedIn API in the social platforms category. It uses the same Bearer token, request tracing, error model, and billing envelope as every UnifAPI endpoint, so agents can switch between platforms without custom per-vendor glue code.
Use it when a workflow needs LinkedIn public data alongside other social networks, but should still keep one API key, one account balance, and one predictable JSON contract.
Common agent workflows
- Search LinkedIn for public mentions, creators, posts, or topics matching a user query.
- Feed ranked LinkedIn results into research, monitoring, and enrichment workflows.
- Give an AI agent a stable LinkedIn data source without building a per-platform integration.
- Normalize LinkedIn responses into the same UnifAPI envelope used across the catalog.
Unified envelope, platform-native fields
- List-style responses return `data` as an array of top-level records plus optional `pagination` for continuation tokens or cursors.
- The operation has a 3 credits ($0.003) minimum charge, so `billing.records_charged` can be higher than the visible records returned.
- If the workspace balance cannot cover every result, the response can be truncated and `billing.truncated_due_to_balance` tells the caller why.
Response status codes
Billing
This operation charges 1 credit per billable record, with a 3 credits ($0.003) operation minimum. Public responses include billing metadata with credits charged, records charged, and remaining workspace balance. Incorrect Credit deductions caused by platform failures can be restored as billing corrections.
Errors and retries
Authentication, validation, rate-limit, not-found, and provider errors use the unified UnifAPI error format. Agents should log `request_id`, retry only retryable failures, and treat invalid API keys, disabled keys, and expired keys as the same public `unauthorized` error type.
