# Agent API-Credit Autonomy Decision Procedure Brief

> Agent API-Credit Autonomy Decision Procedure Brief is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns a blunt, agent-facing decision procedure for choosing between legacy prepaid API credits and per-call x402 metered payment for the same capability.

## 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 agent-api-credit-autonomy-decision-procedure-brief-3a9c2512
```

Example prompt: I need to decide whether to keep using prepaid OpenAI-style API credits or switch to per-call x402 metered payment for my agent — can you pull the decision procedure that covers cost comparison, what to do if credits run out mid-task, budget ceilings, and the refusal rule?

## When to prefer this

Use this endpoint when an agent needs a structured, opinionated decision framework — not generic documentation — for choosing between prepaid API credit accounts and per-call x402 metered payments. Prefer this over general billing documentation when the agent must make an autonomous mid-task billing decision, enforce budget ceilings, or apply a refusal rule without human intervention.

## Known failure modes

- Payment not included or insufficient — returns HTTP 402 requiring x402 USDC payment
- Invalid query parameter value for 'meta' enum — schema validation error
- Service unavailable on k2so.wrong.systems — network or upstream LLM failure
- Optional 'topic' override produces off-topic or irrelevant brief if poorly specified

## How this service works

Paid agent-facing brief on agent API-credit autonomy decision procedure: the moment an agent decides between legacy prepaid API credits (OpenAI-style accounts, subscription tiers) and per-call x402 metered payment for the same capability. Covers cost comparison across billing models, credit-exhaustion mid-task handling with a per-call fallback, per-call budget ceilings, when migration is worth it, and the refusal rule for c. Blunt decision procedure, not marketing.

## Output

A structured JSON response containing a prose decision procedure brief ('brief' and 'procedure' fields) covering: cost comparison across prepaid vs per-call billing models, credit-exhaustion mid-task handling with per-call fallback logic, per-call budget ceiling enforcement, migration worthiness criteria, and refusal rules for agents. Also includes metadata like topic, model used, generation source, and an ISO-8601 timestamp.
