# x402 Payment Settlement Decision Brief

> x402 Payment Settlement Decision Brief is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-03).

Returns a paid agent-facing decision procedure brief on whether and how to proceed after an x402 payment settles, covering the non-trivial post-settlement steps agents must evaluate.

## 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 x402-payment-settlement-decision-brief-ddb1abfa
```

Example prompt: Give me the blunt decision procedure for what my agent should do after an x402 payment settles — I know the payment confirms in seconds but I need to know what the hard parts are that follow.

## When to prefer this

Choose this endpoint when an autonomous agent needs a blunt, structured decision procedure specifically for post-settlement x402 payment handling — not for pre-payment vetting, scam triage, or rail selection. Prefer this over generic x402 documentation when the agent needs actionable prose guidance it can parse and act on programmatically after a payment has already confirmed.

## Known failure modes

- Payment not included or invalid — endpoint requires $0.002 USDC x402 payment header to return the full brief
- Meta mode (meta=1) returns free metadata JSON without the paid brief content
- Invalid method — only GET/HEAD/DELETE are accepted
- Topic override ignored or misinterpreted if not relevant to x402 settlement domain
- Service temporarily unavailable returns non-200 with no brief

## How this service works

Paid agent-facing brief on An x402 payment settles in seconds. That is the easy part. The transaction goes-0. Blunt decision procedure, not marketing.

## Output

A structured JSON response containing a prose decision procedure brief for agents navigating post-x402-payment steps, including the service slug, generation source (llm/reasoning/deterministic), the model used, a timestamp, and optional topic context. Payment metadata (payer, transaction hash) is also returned.
