Access
- Runs on looot’s key for 8 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
7 per call (from $0.0495), 1 free. A call that fails at the provider costs $0; see What’s free.
Free first in fallback
Yes. 1 endpoint cost $0, and a $0 row is tried ahead of the paid rows in its bucket. See Free first.
Run it
A job run takes shared input names, not BuiltWith’s own field names; looot maps them for each provider. For job:company.technographics, domain is taken by 5 of its 6 providers. See Job inputs.
Example input for looot run or the MCP run tool, with placeholder values:
looot run job:company.technographics --input '{"domain":"example.com"}'{
"endpointId": "job:company.technographics",
"input": {
"domain": "example.com"
},
"idempotencyKey": "<new unique key>"
}A job run picks among all the job’s providers. To run BuiltWith itself, name one of its endpoints (MCP search with {"filters": {"provider": "builtwith"}} lists them), for example builtwith-api-json: looot inspect builtwith-api-json prints its exact input fields and price.
