## 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 html-strip-tool-gpt-5-5-x402-gateway-41bf964b
```

Example prompt: Strip the HTML tags out of this snippet and give me just the plain text, with a max of 500 characters: '<h1>Hello World</h1><p>This is a <strong>test</strong> page.</p>'

## When to prefer this

Prefer this endpoint when you need a fast, cheap ($0.0001 USDC), no-subscription way to strip HTML to plain text without spinning up your own parser — especially useful in x402-compatible micropayment pipelines on Base where per-call billing is desirable.

## Known failure modes

- Missing 'html' query parameter returns a validation error
- HTML input exceeding 50,000 characters is rejected
- max_chars value outside 100–20,000 range returns a schema error
- Payment failure or insufficient USDC balance results in 402 response
- Malformed or non-HTML input may return an empty or unexpected text result

## How this service works

Remove HTML tags, scripts, styles, and common entities from short HTML snippets without calling an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.

## Output

A JSON object with ok: true, the tool name 'htmlStrip', the clean plain-text version of the input HTML, and a fetchedAt timestamp. Returns up to max_chars characters of stripped text if the optional limit is specified.
