Overview

The POST variant of Semantic Search takes the same parameters in a JSON body, with filters as a native object instead of a URL-encoded string. Use it when an exclude.domains list is too large to fit a GET URL.

Example request

export EXTRUCT_API_TOKEN="YOUR_API_TOKEN"

curl -X POST "https://api.extruct.ai/v1/companies/search" \
  -H "Authorization: Bearer ${EXTRUCT_API_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "q": "b2b treasury automation",
    "filters": {
      "include": {"country": ["United States"], "size": ["51-200"]},
      "exclude": {"domains": ["stripe.com", "adyen.com"]}
    },
    "pagination": {"offset": 0, "limit": 20}
  }'

Key parameters

q (required): Natural-language query.
filters (optional): SearchFilters as a JSON object. See Search Filters Reference.
pagination (optional): { "offset": <int>, "limit": <int> }; limit up to 250 per request.

Endpoint behavior

Identical ranking and results to GET /v1/companies/search; only the transport differs.
Prefer POST when exclude.domains is large; otherwise either method works.
A single request returns at most 250 results. Page with pagination.offset to read deeper: paid plans (Starter, Pro) can reach up to 2,000 results per query; the free tier is capped at 25.

Success signal

Returns results and request metadata, the same shape as the GET endpoint. Reuse results[].id or results[].domain as downstream identifiers.

Common errors

`401 Unauthorized`

Check that your header is Authorization: Bearer ${EXTRUCT_API_TOKEN}.

`422 Unprocessable Entity`

An invalid domain in exclude.domains, more than 1000 domains after de-duplication, or a malformed body. Validate before sending:

echo '<body-json>' | jq empty
