## 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 agentproof-verify-business-contact-4d28bc71 -d '<json body>'
```

Example prompt: Can you verify the business contact for Acme Supplies — contact name Jane Doe, email jane@acmesupplies.com, phone +1-555-234-5678 — and give me a provenance receipt with the integrity hash before I authorize any payments to them?

## When to prefer this

Choose this endpoint when an autonomous agent needs a cryptographically attested, machine-paid proof that a business contact was verified prior to executing a transaction — especially in agentic commerce pipelines where auditability and non-repudiation of due diligence matter. Prefer it over generic contact lookup APIs when you need a tamper-evident receipt (integrity SHA-256) rather than just a lookup result.

## Known failure modes

- Invalid or missing contact fields return a validation error
- Unresolvable business contact results in ok:false or empty receipt
- Payment failure (x402) prevents the call from completing
- Duplicate or malformed email/phone causes rejection
- Network timeout returns no receipt, requiring retry

## How this service works

AgentProof publishes Agent Transaction Passport™ and provides machine-paid evidence, provenance receipts, source comparison and change monitoring for autonomous transactions.

## Output

Returns a JSON object with ok:true, the tool name 'verify_business_contact', a receipt object containing a UUID receipt ID and an integrity_sha256 hash, and the service name 'AgentProof'. This constitutes a machine-paid provenance record attesting that the business contact verification was performed.
