How this service works

Create media, research companies and people, publish to the web, remember context, deploy apps, and schedule work—on demand, without vendor accounts or API keys. This server is a pay-per-use, transparent proxy in front of WithZero's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge.

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

When 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
