Search for companies by keywords, location, industry, and employee count via Apollo — $0.02/request.
What it does
The Apollo Org Search endpoint on StableEnrich lets you find organizations matching keyword, location, employee-count, industry, and domain filters. It is a POST endpoint at `https://stableenrich.dev/api/apollo/org-search` priced at $0.02 per request, paid via micropayment (x402 or MPP/Tempo) with no API keys or subscriptions required.
The endpoint returns paginated results (up to 100 per page) with rich organization data including name, domain, website, LinkedIn/Twitter/Facebook URLs, industry, employee count, annual revenue, total funding, funding stage, headquarters address, technologies used, and more. It supports `excludeFields` to reduce response size. This endpoint is commonly used as a prerequisite step before Apollo People Search — verifying the exact `organization_id` or domain prevents wasted calls on misspelled or incorrect identifiers.
StableEnrich is part of a broader pay-per-request research platform by Merit Systems that unifies Apollo, Exa, Firecrawl, Google Maps, Serper, Whitepages, Clado, Minerva, Reddit, Hunter, Influencer, and Cloudflare Browser Rendering APIs behind a single origin. Payments settle on Base mainnet (EIP-155:8453), Solana, or Tempo L2. Full OpenAPI 3.1 schemas and request/response types are published.

Quality
Full OpenAPI 3.1 schema with detailed request/response types, clear pricing ($0.02/request), comprehensive documentation and guidance. The endpoint returned 405 on HEAD/GET probes (expected since it's POST-only), so no live 402 challenge was captured, but the OpenAPI spec and x-payment-info confirm it is live and correctly configured.
Warnings
- —Probe returned 405 on HEAD and GET because this is a POST-only endpoint; no 402 challenge was directly captured during probing.
- —Response example is illustrative — actual field values will vary based on Apollo's data.
