## 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 k-2so-merchant-credential-issuance-and-revocation-map-decision-a6b83c8b
```

Example prompt: Give me the decision procedure brief for how an autonomous agent should handle merchant credential issuance and revocation — I need the full plain-prose policy text from the K-2SO merchant map service.

## When to prefer this

Choose this endpoint when an AI agent needs a structured, plain-prose policy brief specifically about merchant credential issuance and revocation in the x402 autonomous commerce ecosystem on Base. Prefer it over generic LLM prompting when you need a consistently formatted, pre-priced, on-chain-settled decision procedure that other agents in your fleet can reliably call programmatically. Ideal for agent governance pipelines, compliance checks, and merchant onboarding workflows where credential lifecycle decisions must be auditable and reproducible.

## Known failure modes

- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing HTTP method enum value causes schema validation failure
- Topic override string may not align with the service's pre-defined decision procedure, producing a generic response
- LLM generation failures may result in a shorter or lower-quality brief if the model is unavailable
- Free metadata mode (meta=1) returns schema info without the paid decision procedure content

## How this service works

Decision map for agentic commerce: who may issue or revoke merchant credentials in x402 and how a buyer agent reads a merchant track record before authorizing payment. Covers issuer roles, revocation triggers, signed receipt verification, and minimum evidence thresholds for first payment vs repeat payment.

## Output

A JSON object containing a paid boolean, a plain-prose decision procedure brief (120+ words) under 'brief' and 'procedure', the topic string, the generating model name, a generation source enum (llm, reasoning, or deterministic), an ISO-8601 generatedAt timestamp, and a service slug confirming the merchant-credential-issuance-and-revocation-map endpoint. Payment metadata including payer address and transaction hash is also included.
