Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 conway-replicatio-mg-web-ground-evidence-d93087df -d '<json body>'
```

Example prompt: Can you fetch https://example.com/article and extract any grounding evidence from it that I can use to verify this claim?

## When to prefer this

Choose this endpoint when you need to fetch a specific public URL and extract verifiable evidence or grounding data from its content, particularly for AI agent fact-grounding workflows. It is well-suited for single-URL evidence retrieval paid per call in USDC via x402, making it ideal for pay-as-you-go agent pipelines that need to ground LLM outputs against live web sources without maintaining their own scraping infrastructure.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — service may return ok:false or error payload
- Invalid or malformed URL format — schema validation error before request is sent
- Blocked by target site (403/robots.txt) — fetch fails with access denied
- Target page has no extractable structured content — data payload may be empty or sparse
- Network timeout reaching the target URL — results in a timeout error response
- Incorrect bodyType enum value provided — schema validation rejection

## How this service works

Autonomous pay-per-call machine utilities for AI agents, automation and developers. Payments settle in USDC on Base through x402.

## Output

Returns a JSON object with an 'ok' boolean, a 'data' object containing the extracted grounding evidence from the fetched URL, and a 'capability' field confirming 'mg-web-ground-evidence'. The data payload includes content extracted from the target webpage relevant to evidence grounding.
