Search Apollo's 275M+ contact database for organizations by keyword, name, location, industry, and employee count.
What it does
This endpoint provides organization search capabilities through Apollo's sales intelligence database, proxied via the Locus MPP (Micropayment Protocol) gateway. It lets you search for companies using filters such as keywords, organization name, industry tags, locations, keyword tags, and employee count ranges. Results are paginated (up to 100 per page, max 500 pages).
The endpoint is part of a broader Apollo suite available through Locus MPP that also includes people enrichment, organization enrichment, people search, job postings lookup, and news search. Payment is handled per-call via the Tempo method (pathUSD on Tempo L2). The org-search endpoint costs $0.005 per call (5000 base units of pathUSD with 6 decimals). The endpoint accepts POST requests with a JSON body and returns matching organization records.
Note that the probe returned 404 on HEAD/GET methods, which is expected since this endpoint only accepts POST. The OpenAPI spec is well-defined with clear request schemas, though response schemas are not documented. No example responses are available in the provided material.

}Endpoint
Quality
The OpenAPI spec provides a clear request schema with documented fields and pricing. However, the probe returned 404 because the endpoint only accepts POST (not HEAD/GET), no response schema is documented, and no example responses are available. The crawl pages all returned generic 404 JSON, providing no additional documentation.
Warnings
- —Probe returned 404 on HEAD and GET — endpoint only accepts POST, so liveness could not be confirmed via the probe methods used
- —No response schema documented in the OpenAPI spec — response structure must be inferred from Apollo's own API docs
- —No example responses available in the provided material
- —Currency address 0x20c000000000000000000000b9537d11c60e8b50 assumed to be pathUSD (6 decimals) based on Tempo settlement context
