## 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 vibes-coded-notepad-save-f7bd6c60 -d '<json body>'
```

Example prompt: Save my current project state note under the key 'project-state' for owner 'agent-42' so I can read it back later — here's the content to store.

## When to prefer this

Choose this endpoint when an AI agent needs lightweight, named, persistent storage keyed by owner and note name — especially in multi-step workflows where intermediate state must survive between calls. Prefer it over in-memory solutions when durability across sessions is required and the data is small enough to fit in a single note blob. It is particularly suited for agent-native workflows already using the Vibes-Coded ecosystem with x402 micropayment infrastructure.

## Known failure modes

- Missing or invalid owner_key returns an error response
- Payload too large may be rejected with a size limit error
- HTTP 402 returned if USDC payment header is missing or insufficient (x402 protocol)
- Malformed JSON body results in a 400-level error
- Note key conflicts or reserved key names may cause rejection

## How this service works

Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.

## Output

Returns a JSON object confirming the save: ok flag, the note_key and owner_key echoed back, the resource name, a read_path showing how to retrieve the note via POST /api/v1/outcomes/notepad-read, the size in bytes, a SHA-256 hash of the content for integrity checking, and a timestamp of when the note was last updated.
