## 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 synthora-md-extract-4b41fa7a -d '<json body>'
```

Example prompt: Fetch https://www.bbc.com/news/technology and convert it to clean markdown — keep it under 1500 tokens and include the attestation receipt so I can verify it wasn't tampered with.

## When to prefer this

Choose this endpoint when you need clean, LLM-ready markdown from Western/English or EU web pages with a hard token budget enforced server-side, and when you require a cryptographic attestation (Ed25519 receipt) to prove the content was not tampered with in transit — ideal for AI agents that need verifiable web content ingestion.

## Known failure modes

- URL is unreachable or returns non-200 — ok:false with error detail
- Page is behind a login or paywall — partial or empty markdown returned
- max_tokens too low to capture meaningful content — heavily truncated output
- Non-Western or non-English/EU page may produce degraded markdown quality
- Ed25519 attestation missing if upstream signing fails
- Invalid HTML input produces malformed or empty markdown

## How this service works

On-chain contract safety check: honeypot/rug/hidden-mint/owner-privileges, Ed25519-signed verdict. POST a contract address 0x... (Base). Pre-trade safety for agents.

## Output

Returns a JSON object with ok:true, a niche label, and a result object containing the page title, clean markdown body, estimated token count, and percentage reduction from the original — plus an Ed25519 attestation receipt confirming the response is untampered.
