# Async Job Payment Lifecycle Decision Procedure for Agents

> Async Job Payment Lifecycle Decision Procedure for Agents 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 2026-09-13).

Returns a deterministic decision procedure guiding AI agents through the payment lifecycle for long-running asynchronous jobs over x402/MPP, covering submission, polling, cancellation, timeouts, and job-status interpretation.

## 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 async-job-payment-lifecycle-decision-procedure-for-agents-509e9312
```

Example prompt: I need the decision procedure for paying for a long-running async video generation job over x402 — specifically how to split the submission payment, manage polling budgets, handle cancel-before-completion refunds, and interpret job status codes like queued, running, succeeded, and failed.

## When to prefer this

Choose this endpoint when your agent needs authoritative, structured guidance on handling payment lifecycle decisions for async or long-running jobs over x402/MPP — especially when you need concrete rules for polling budgets, cancellation thresholds, timeout recovery, and status-code interpretation. Prefer this over general x402 documentation when the job type is asynchronous (video generation, scraping, batch inference) and deterministic guardrails are needed rather than open-ended advice.

## Known failure modes

- Invalid or missing method parameter returns validation error
- Unrecognized topic override may result in fallback to default procedure
- Service unavailability returns non-200 with no procedure content
- Payment not made (no x402 header) results in 402 Payment Required with payment details
- Meta flag set to 1 returns free metadata instead of paid procedure content

## How this service works

Deterministic procedure for an agent that must pay for a long-running or asynchronous job over x402/MPP (video generation, scraping, inference, batch processing). Covers: submit-payment split (pay only for submission, never for the whole job up front), polling budget with max polls and max total spend across polls, cancel-before-completion refund thresholds, resume-after-timeout rules with re-payment guardrails, job-status code interpretation (queued/running/succeeded/failed/canceled), and a

## Output

A structured decision procedure document containing prose guidance for agents covering: how to split payments at job submission vs. completion, polling budget limits with max poll counts and max total spend, cancel-before-completion refund thresholds, resume-after-timeout re-payment rules and guardrails, and an interpretation guide for job-status codes (queued, running, succeeded, failed, canceled). Also includes metadata such as generation source (llm, reasoning, or deterministic), ISO-8601 timestamp, topic, and service slug.
