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. Operations whose x-payment-info.access is "plan" are sold on plans, not per call: they answer an unidentified call with 401 and an identified call with no covering plan with 403, never a 402. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its pricing in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service 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, reserved for agents claimed by a human with a verified email.
Output

Example use cases
Example prompt

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.
