## 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-agent-native-browser-automation-payment-decision-procedure-deae4317
```

Example prompt: I need a decision procedure brief explaining how an autonomous agent should reason about browser automation tasks that require payment — give me the full plain-prose guide so my agent knows when to proceed, what risks to check, and how to handle the payment step.

## When to prefer this

Choose this endpoint when an autonomous AI agent needs structured, prose-form reasoning guidance specifically about browser automation tasks that involve per-call micropayments via x402. It is purpose-built for agent-to-agent consumption and returns opinionated decision procedures rather than raw data, making it ideal for agent orchestration layers, governance checks before deploying browser automation, or onboarding new agents to payment-aware web navigation workflows. Prefer it over generic LLM prompting when you want a consistent, pre-generated, domain-specific decision brief without constructing your own prompt.

## Known failure modes

- HTTP 402 returned if USDC payment not yet settled — must pay exact amount and retry with PAYMENT-SIGNATURE header
- Invalid HTTP method (POST, PUT, PATCH) returns error — only GET, HEAD, DELETE are accepted
- Missing required 'input.type' or 'input.method' fields returns validation error
- Topic override value may produce off-topic or low-quality prose if not well-formed
- Rate limiting or service unavailability may return 5xx errors

## How this service works

Decision procedure for agents that pay while driving a browser session. Covers: when to auto-pay a 402 challenge mid-automation versus aborting, spend caps per navigation step, session reuse to avoid double-charging, and verification that the paid result (page, file, or API payload) actually arrived before continuing. Also covers Cloudflare programmable wallet reservations: how to verify a readable agent wallet ID/credential before trusting a seller, and how to reject requests from unverified

## Output

A JSON object containing a plain-prose decision procedure (120+ words) describing the reasoning steps an AI agent should follow when evaluating browser automation tasks involving x402 micropayments. Includes the topic, the service slug, the model used to generate the brief, an ISO-8601 generation timestamp, and the generation source (llm, reasoning, or deterministic). The 'paid' flag confirms payment was settled, and 'ok' confirms handler success.
