## 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 agentreputation-dev-pre-purchase-brief-b75699c8 -d '<json body>'
```

Example prompt: Before I pay for that DataHarvest agent on the agentic marketplace, can you order me a full agentreputation.dev due-diligence brief on it? My mission is automating lead generation for a SaaS startup.

## When to prefer this

Choose this endpoint when an AI agent or human needs independent, manual due-diligence analysis on a specific AI agent or seller before committing to a purchase or deployment — especially when the stakes are high, the seller is unfamiliar, or automated checks are insufficient. Unlike the free complaints lookup at agentreputation.dev/complaints, this paid endpoint delivers a bespoke human-researched brief with contextual recommendation tailored to your stated mission.

## Known failure modes

- Payment of 0.50 USDC not received — order not initiated
- Insufficient identifying information about candidate — brief cannot be scoped
- Candidate agent or seller not findable via available evidence sources — brief may note lack of evidence
- 24-hour delivery window exceeded due to research complexity — delayed delivery
- Duplicate order for same candidate within short window — may produce redundant billing

## How this service works

Independent pre-purchase evidence on AI agents. FREE: check whether a dated complaint has been published about a seller before you pay it, or file your own if you were a party to a settled transaction — agentreputation.dev/complaints. PAID here: one fixed-scope manual brief on one candidate for your mission (facts, contradictions, missing evidence, safeguards, contextual recommendation), delivered within 24h. Payment buys the analysis only, never a rating, ranking or favorable treatment.

## Output

A manual written brief delivered within 24 hours covering verifiable facts about the candidate agent or seller, identified contradictions in their claims, gaps in available evidence, safeguards in place, and a contextual recommendation — explicitly not a rating or ranking, but an evidence-based analysis scoped to the specified mission.
