## 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 losbeto-web-fetch-public-url-retrieval-via-x402-ba4e1f16
```

Example prompt: Can you fetch the contents of https://api.exchangerate.host/latest and return the response body so I can see the current exchange rates?

## When to prefer this

Use this endpoint when an AI agent needs to read a live public URL — a webpage, public REST API, or document — without setting up API keys or accounts. It is particularly useful for agents that need content beyond their training cutoff, need to browse links mid-task, or need to call a public API and get back a clean JSON-wrapped response. Payment is per-call in USDC via x402 so no subscription is required.

## Known failure modes

- Private or internal IP ranges refused with an error (no localhost, RFC1918 addresses)
- Non-public URLs or authenticated endpoints return access errors
- Very large response bodies may be truncated at the size cap
- Non-HTTP/HTTPS schemes are rejected
- Unreachable or offline URLs return a timeout or connection error
- Malformed URLs return validation errors

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

A JSON object containing the HTTP status code, content type, final URL after any redirects, and the full response body as text (size-capped). This lets the agent read live web content, public APIs, or documents that may be beyond its training cutoff.
