## 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-purchase-intent-delegation-record-schema-decision-procedure-1335668d
```

Example prompt: Give me the decision procedure for how an AI agent should record and delegate purchase intent — what fields and logic should a delegation record include when the agent is buying something on behalf of a user via x402?

## When to prefer this

Choose this endpoint when an AI agent needs authoritative, LLM-generated procedural guidance specifically on how to record and delegate purchase intent in x402 payment contexts — especially when building compliant agent wallets, auditing agent purchase authorization chains, or onboarding agents to autonomous merchant ecosystems on Base. Prefer this over generic documentation when you need a machine-readable prose brief tailored to agent decision-making at $0.002 per call.

## Known failure modes

- HTTP 402 returned if payment has not been settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing method enum value causes schema validation failure
- Malformed queryParams (e.g. meta not '0' or '1') may return a 400 error
- Service may return ok:false with an error message if LLM generation fails
- Network or agent infrastructure downtime on k2so.wrong.systems

## How this service works

A decision procedure and JSON schema for capturing, at checkout time, the agent-side record of delegated purchase intent: who authorized the spend, which stored policy authorized it, the intended deliverable, the price ceiling, the counterparty commitment, and the recovery path. Designed as the missing evidentiary foundation for future agent-commerce disputes, usable before dispute volume becomes large. Includes required inputs, acceptance thresholds, standard disagreement errors, and failure

## Output

A JSON object containing a plain-prose decision procedure (120+ words) explaining how an agent should handle purchase intent delegation records, including the topic, model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service slug — all wrapped in a paid response envelope with provider confirmation.
