Look up company details (industry, headcount, tech stack, etc.) by domain via Hunter's API, paid per call on Tempo L2.
What it does
The Hunter Company Enrichment endpoint, served through the Locus MPP gateway, returns structured company data for a given domain. You POST a JSON body with a required `domain` field (e.g. "stripe.com") and receive enrichment data such as industry, headcount, location, technologies used, and other firmographic details sourced from Hunter.io's database.
This specific endpoint (`/hunter/company-enrichment`) is one of eight Hunter endpoints available on this MPP host. Others include Domain Search, Email Finder, Email Verifier, Email Enrichment, Combined Enrichment, Discover Companies, and Email Count. Payment is handled via the MPP protocol using the Tempo method (pathUSD on Tempo L2). The company-enrichment call costs 13,000 base units of pathUSD (6 decimals), which equals $0.013 per request.
The endpoint accepts POST requests with `application/json` content type. The only required field is `domain`. The OpenAPI spec does not include a response schema, so the exact shape of the returned company object is not documented here; refer to Hunter.io's API documentation (v2) for field-level details on what company enrichment returns. Note that the probe returned 404 on HEAD/GET — this is expected since the endpoint only accepts POST.

}Endpoint
Quality
The OpenAPI spec provides clear request schema and pricing for this endpoint, but no response schema or example responses are available. The probe returned 404 because it used HEAD/GET on a POST-only endpoint, so liveness is not confirmed but likely. No crawled pages returned useful documentation.
Warnings
- —Endpoint returned 404 on HEAD and GET probes; it only accepts POST, so liveness is not directly confirmed by the probe.
- —No response schema is documented — consumers must refer to Hunter.io's own API docs for the shape of the returned data.
- —Crawled pages on the MPP host all returned 404 JSON errors; no additional documentation was found on the gateway itself.
