## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fullenrich-company-lookup-ddabb324 -d '<json body>'
```

Example prompt: Look up the company profile for acme.com using FullEnrich — I need their name, headcount range, and any other firmographic details you can pull.

## When to prefer this

Use this endpoint when you need quick, pay-per-call firmographic enrichment for a company record — especially useful in agentic workflows where you have no pre-existing FullEnrich API key or subscription. Prefer this over person-level enrichment endpoints when the goal is company-level data (name, size, domain). Choose it when you have a company domain, LinkedIn company ID, or LinkedIn URL as your identifier.

## Known failure modes

- No match found if domain/ID/URL is unrecognized or too new — returns empty matches array
- Invalid domain format causes input validation error
- Missing all three identifier fields (domain, professional_network_id, professional_network_url) results in error
- Payment failure over x402 rails prevents call from completing
- Rate or quota limits may apply per wallet/agent identity

## How this service works

Per-call B2B person + company enrichment for autonomous agents, powered by FullEnrich. Pay per successful call over agent payment rails; no API key or account.

## Output

A JSON object with a total count of matches and an array of matched company records, each containing the company name, domain, and headcount range (e.g. '51-200').
