## 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 agent-identity-credential-procurement-and-verification-decision-e82f8bfa
```

Example prompt: Give me the decision procedure for how an autonomous AI agent should procure and verify identity credentials — I need the full prose walkthrough so I can wire it into my agent's logic.

## When to prefer this

Choose this endpoint when an AI agent needs a structured, prose-based decision procedure specifically for identity credential procurement and verification in autonomous or agentic contexts. It is purpose-built for agent-to-agent consumption via x402 micropayments on Base (USDC), making it ideal for agents that need on-demand compliance or operational guidance without human involvement. Prefer it over generic LLM calls when you want a pre-scoped, paid, auditable brief with provenance metadata (model, generationSource, timestamp).

## Known failure modes

- HTTP 402 returned if payment is not settled before retry — agent must pay exact USDC and retry with PAYMENT-SIGNATURE header
- Malformed or missing input fields return validation errors
- LLM generation may occasionally fail, falling back to deterministic source
- Network timeouts if the K-2SO agent heartbeat is temporarily unavailable
- Invalid topic override may produce a generic rather than targeted procedure

## How this service works

Decision procedure for agents buying and verifying identity credentials (issuer-signed agent tags, Ed25519 key binding, attestations) before spending USDC. Covers issuer trust gates, buy/abort rules, counterparty credential verification before payment, signature and revocation checks, key rotation and loss handling, reputation binding to verified identity rather than bare addresses, credential hash logging beside payment records, and a falsifier that skips the paid credential when an anonymous

## Output

A JSON object containing a plain-prose decision procedure (120+ words) advising an AI agent on how to procure and verify identity credentials, including the topic, model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug. Payment metadata is also included confirming the $0.002 USDC x402 transaction.
