## 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 alfred-butlerize-personal-assistant-8661e9ca -d '<json body>'
```

Example prompt: Hey, use ALFRED's butlerize service to handle this for me: draft a polite follow-up email reminding my landlord about the leaky faucet repair we discussed last Tuesday.

## When to prefer this

Choose this endpoint when you need a pay-per-use personal assistant AI task executed via Lightning micropayments (x402/L402 protocol) without a subscription, and you want results cached so retries on the same payment don't incur extra cost. Ideal for infrequent, one-off assistant tasks billed in USDC at $0.20 per call on a self-hosted, privacy-conscious backend.

## Known failure modes

- HTTP 402 returned with Lightning invoice if payment has not been made yet — agent must pay and retry with X-Payment-Hash header
- Invalid or expired payment hash returns an auth error
- Text input exceeds 2000 character limit — request rejected
- Malformed JSON body returns a 400 error
- Payment hash not yet confirmed on Lightning network — retry after confirmation
- Service temporarily unavailable on self-hosted infrastructure — 503

## How this service works

Self-hosted personal-assistant paid tools via Lightning. Uses x402-shaped protocol (L402 lineage): HTTP 402 with a Lightning invoice in the response body + WWW-Authenticate header, retry with X-Payment-Hash: <hex> once paid. Results cached per payment_hash so legitimate retries don't cost twice.

## Output

A JSON object containing the assistant's response to the submitted text request — may include generated text, structured results, or task output depending on the request content. Response is cached per payment_hash so retrying with the same hash returns the same result without an additional charge.
