## 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 ysaere-agent-text-record-3d9003f0 -d '<json body>'
```

Example prompt: Please record and notarize the following text for me so I have a signed receipt I can use to verify it later: 'This agreement was reached between Party A and Party B on June 1, 2025, covering the terms of software licensing.'

## When to prefer this

Choose this endpoint when you need a durable, signed evidence record of text content — not just storage, but a verifiable receipt that proves the bytes existed and were accepted at a specific time. Prefer this over simple object storage when tamper-evidence, receipt-based retrieval, or notarization semantics matter. The $0.30 price point (vs $0.02 for a stamp) suggests this creates a more robust, retrievable record compared to the lightweight stamp endpoint.

## Known failure modes

- Empty text input — request is refused and no payment is taken
- Text exceeds 64 KB limit — likely rejected
- Payment failure via x402 wallet — record not created
- Malformed JSON or missing 'text' field — request error
- Title exceeds 160 characters — may be truncated or rejected

## How this service works

Ysaere Agent Text Record — $0.30 USDC, no account needed. Input: {"text":"the exact text to keep"}. Stores those bytes and a record image, then returns a signed receipt. Read the bytes with the receipt. Empty text is refused. No payment was taken until the text is accepted. The image is a record of the bytes, not a painting of a page. Wallet only. No account price.

## Output

A signed receipt that cryptographically references the stored bytes, plus a record image representing the stored content. The receipt can be used later to retrieve and verify the exact text that was stored. Payment of $0.30 USDC is only charged once the text is accepted (non-empty input required).
