## 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 manylives-bot-answer-checker-c4c80ec0 -d '<json body>'
```

Example prompt: Check whether these two chatbot answers are accurate against my bike shop's support page at https://example-bikes.com/contact — the bot said we're open 10am–4pm on Sundays and that a standard service costs £60, but I need to know if either claim is contradicted or unsupported.

## When to prefer this

Use this endpoint when you need to systematically audit chatbot or AI assistant outputs against a ground-truth source (your own docs or website) and require claim-level evidence with specific quotes and source URLs. It is especially valuable for regulated industries, customer support quality control, or pre-launch bot validation where fabricated figures or policy contradictions carry real risk. Prefer this over generic AI fact-checkers when you control the authoritative source and need structured, auditable results tied to specific pages.

## Known failure modes

- URLs are inaccessible or behind authentication — the endpoint cannot fetch page content and may return unsupported verdicts for all claims
- Text input exceeds 60,000 characters — request will be rejected or truncated
- More than 25 question-answer pairs submitted — pairs beyond the limit may be ignored
- Bot answers exceed 1,500 characters each — long answers may be truncated before analysis
- Ambiguous or vague claims that cannot be matched to specific source text — may return 'unsupported' even if implicitly correct

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

A JSON object containing a per-answer breakdown with claim-level verdicts ('supported', 'unsupported', or 'contradicted'), the exact quote from the source that supports or contradicts each claim, the source URL where the quote was found, and a list of any figures in the bot's answer that do not appear in the sources. Also includes a summary object with total counts of supported, unsupported, and contradicted answers.
