## 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 tollkit-attest-screenshot-e84748f9 -d '<json body>'
```

Example prompt: Take a screenshot of https://example.com/pricing and give me a signed, timestamped attestation proving what the page says right now.

## When to prefer this

Choose this endpoint when you need cryptographically signed, timestamped proof of what a web page displayed at a specific moment — not just a raw screenshot. It is ideal for legal evidence, compliance archiving, price dispute documentation, or any scenario where verifiability and tamper-evidence matter. It requires no account or API key, making it easy to invoke on-demand from an agent using x402 micropayments. Prefer it over generic screenshot tools when attestation and provenance of the captured content are critical.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — attestation cannot be completed
- Payment via x402 fails or USDC balance is insufficient — request is rejected before capture
- URL is malformed or not an absolute http/https URI — schema validation error
- Target page takes too long to load — capture may time out
- Payment on unsupported chain — only Base and Solana USDC are accepted

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

Returns a signed, timestamped attestation bundle including a screenshot image of the target page rendered at 1280×800, along with cryptographic evidence (signature and timestamp) proving the page's content at the time of capture. This can be used as tamper-evident proof of what a web page displayed.
