## 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 post-payment-accountability-resolution-for-agent-transactions-086c51ed
```

Example prompt: Give me the decision procedure for how I should handle post-payment accountability and resolution after completing an x402 USDC transaction — what steps should I take if something goes wrong or I need to audit what happened?

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, LLM-generated decision procedure specifically for post-payment accountability — especially in x402 micropayment workflows on Base/USDC where the agent must autonomously determine what to do after a transaction, handle disputes, or maintain audit trails without human intervention. Prefer over generic legal or compliance APIs when the context is agent-to-agent x402 commerce.

## Known failure modes

- HTTP 402 returned if payment not yet settled — agent must complete USDC micropayment and retry with PAYMENT-SIGNATURE header
- Invalid or missing required input fields returns a schema validation error
- LLM generation failure may result in a fallback to deterministic procedure source
- Network timeout on k2so.wrong.systems results in no response
- Incorrect payment amount or wrong USDC address causes payment rejection

## How this service works

Paid agent-facing brief on post-payment accountability resolution for agent transactions: a procedure that assigns who is accountable after an x402 settlement, covering customer-fund custody, regulated/age-restricted purchases, and facilitator liability, matching the gap between agent payment ability and principal accountability · Build a decision procedure or schema for: post-payment accountability resolution for agent tra-0. Blunt decision procedure, not marketing.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) describing how an agent should handle post-payment accountability and resolution, along with metadata including the topic, service slug, generation timestamp, the model used, and generation source (llm, reasoning, or deterministic).
