How this service works
Core workflow route: build a target account page from the cached Crustdata company dataset using provider-native filters, fields, sorts, cursor, aggregations, and limit. Default pricing is $0.10 per Crustdata credit with a $0.01 minimum successful-call settlement. Upstream Crustdata errors settle $0. CompanyDB search is priced at 0.03 Crustdata credits per returned company.
Output
Returns structured company records from Crustdata, including requested field sections such as company name, primary domain, total headcount, and industry taxonomy. May also include aggregation results and a cursor for paginating to the next page of results.
Example use cases
Example prompt
“Search Crustdata for companies whose primary domain is browserbase.com — return their name, domain, and total headcount, limit to 10 results sorted by headcount descending.”
Technical details
Endpoint
POSThttps://agents.withzero.xyz/api/v1/crustdata/company/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search or filter companies programmatically using Crustdata's native filter/sort/aggregation syntax, especially when you have a domain name, industry, or headcount criterion. Prefer this over generic web search when you need structured firmographic data. Ideal for B2B research, lead generation filtering, or enriching a list of companies with headcount and industry data without needing your own Crustdata account.
Side effects
- Invalid or malformed filter conditions return a 400 error
- Cursor value expired or invalid returns a pagination error
- Requested fields not available for the queried dataset return partial or empty results
- Exceeding limit of 100 records per call returns a validation error
- Payment failure or insufficient USDC balance blocks the request
- Rate limits on the underlying Crustdata API may cause 429 errors

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
