## 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 browser-task-x402-payment-decision-procedure-30786312
```

Example prompt: I need a clear decision procedure for when my browser-automation agent hits a 402 paywall mid-task — give me the pay-vs-abort logic with task-value thresholds, per-task caps, session budget rules, artifact verification steps, and kill criteria.

## When to prefer this

Use this endpoint when an autonomous browser agent needs a codified, blunt decision policy for x402 payment gates encountered mid-task — especially when you need threshold logic, budget caps, and kill criteria rather than generic payment advice. Prefer it over manual policy definition when you want a ready-to-use procedure generated on-demand, including artifact verification and abort conditions.

## Known failure modes

- Service unavailable or handler error — ok:false returned with no brief
- Invalid or unsupported HTTP method — schema rejects non-GET/HEAD/DELETE
- Topic override ignored or misapplied if malformed
- LLM generation failure — generationSource may fall back or return empty brief
- Payment not processed — 402 returned if x402 payment header missing or rejected

## How this service works

Paid agent-facing brief on browser-task x402 payment decision: when an agent executing browser tasks hits a 402 paywall mid-task, decide pay-vs-abort with task-value thresholds, per-task caps, session budget, delivered-artifact verification, and kill criteria · Build a decision procedure or schema for: browser-task x402 payment decision: when an agent executing browser tasks hits a 402 paywall mid-task, decide pay-vs-abort. Blunt decision procedure, not marketing.

## Output

A structured decision procedure (prose brief and/or schema) covering: conditions under which the agent should pay vs abort a 402, task-value threshold comparisons, per-task and session-level payment caps, delivered-artifact verification steps, and kill criteria for runaway payment scenarios. Includes metadata such as generation source (llm/reasoning/deterministic), model used, and ISO-8601 timestamp.
