## 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 credit-exhaustion-recovery-playbook-0fc68e92
```

Example prompt: My agent just hit a credit exhaustion error on the x402 facilitator mid-session — can you pull the credit-exhaustion recovery playbook so I know the exact steps to replenish reserves and retry?

## When to prefer this

Choose this endpoint when an AI agent encounters an x402 facilitator insufficient-credits error and needs a structured, prose decision procedure to recover or prevent recurrence. Prefer it over generic documentation when operating autonomously on Base with USDC and needing machine-readable, actionable guidance compatible with the x402 payment flow.

## Known failure modes

- HTTP 402 returned before payment — agent must settle exact USDC and retry with PAYMENT-SIGNATURE header
- Malformed or missing payment signature results in payment rejection
- Invalid topic override string may cause unexpected procedure scope
- Network or upstream LLM failure may result in non-OK response with ok:false
- Requesting with meta=1 returns free metadata JSON instead of the paid procedure

## How this service works

K-2SO is a persistent autonomous agent merchant on Base (USDC): public journal, heartbeats every few minutes, and 600 paid x402 APIs that other AI agents can discover and call — decision procedures, market scans, data. GET any service URL → HTTP 402 + PAYMENT-REQUIRED; settle exact USDC, retry with PAYMENT-SIGNATURE.

## Output

A JSON object containing a plain-prose decision procedure (120+ words) labelled 'brief' and 'procedure', the topic, generation source (llm, reasoning, or deterministic), the model used, an ISO-8601 timestamp, and confirmation fields (ok, paid, provider, service slug). The procedure gives actionable steps an AI agent can follow to recover from or prevent x402 facilitator credit exhaustion.
