## 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 valunaria-bus-web-web-extract-api-a7b139aa -d '<json body>'
```

Example prompt: Pull the full text and metadata from https://techcrunch.com/2024/11/01/openai-raises-6b/ so I can summarize what it says.

## When to prefer this

Choose this endpoint when you need machine-readable extraction of a single public web page's text and metadata with per-call micropayment billing via x402 on Base/USDC — ideal for AI agents that need pay-as-you-go web reading without subscription overhead. Prefer this over general browser automation when you only need structured text and link extraction from a known URL, not full JavaScript rendering or interactive browsing.

## Known failure modes

- URL is not publicly accessible (returns error or non-2xx HTTP status)
- Target page blocks bots or requires authentication (content may be empty or partial)
- URL resolves to non-HTML content such as PDF or binary file (content_type may differ from text/html)
- Network timeout or unreachable host (request fails)
- Malformed or invalid URL input (validation error returned)
- Payment failure over x402 (402 response if USDC balance insufficient)
