Access
- Runs on looot’s key for 13 endpoints: nothing to set up, the run spends your looot balance. You can connect your own key instead; see Bring your own key.
Price basis
1 per call (from $0.0019), 12 charged at the cost the provider reports. A call that fails at the provider costs $0; see What’s free.
Free first in fallback
No. Every endpoint bills on each answer, found or not, so a fallback walk pays for a miss here. See Free first.
Run it
A job run takes shared input names, not The Companies API’s own field names; looot maps them for each provider. For job:company.enrich, domain is taken by 14 of its 20 providers, company is taken by 7 of its 20 providers, linkedin_url is taken by 7 of its 20 providers. See Job inputs.
Example input for looot run or the MCP run tool, with placeholder values:
looot run job:company.enrich --input '{"domain":"example.com","company":"Example Inc","linkedin_url":"https://www.linkedin.com/in/janedoe"}'{
"endpointId": "job:company.enrich",
"input": {
"domain": "example.com",
"company": "Example Inc",
"linkedin_url": "https://www.linkedin.com/in/janedoe"
},
"idempotencyKey": "<new unique key>"
}A job run picks among all the job’s providers. To run The Companies API itself, name one of its endpoints (MCP search with {"filters": {"provider": "thecompaniesapi"}} lists them), for example thecompaniesapi-companies: looot inspect thecompaniesapi-companies prints its exact input fields and price.
