## 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-payable-storage-uploads-decision-procedure-a0826038
```

Example prompt: Give me a blunt decision procedure for whether my agent should use Turbo/ar.io x402 upload rails or stick with existing storage rails — I need the cost gates, content-hash verification logic, retrieval payment semantics, and retention economics explained clearly.

## When to prefer this

Choose this endpoint when an agent needs a structured, opinionated decision procedure — not marketing copy — for routing storage uploads through x402-payable rails. Prefer it over general documentation when you need cost-gate thresholds, content-hash verification logic, and retention economics synthesized into actionable agent-readable rules. Especially useful when building autonomous agents that must make per-upload storage routing decisions programmatically.

## Known failure modes

- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Invalid HTTP method used (only GET/HEAD/DELETE accepted)
- Meta flag set to 1 returns free metadata JSON without the paid decision procedure content
- LLM generation failure may result in empty or partial 'brief' field
- Network timeout or provider downtime returns 5xx error
