## 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 blockchain-money-map-agent-claims-evidence-wall-audit-mode-4933668f -d '<json body>'
```

Example prompt: Run an audit on these blockchain claims and their evidence snippets — I have up to 5 claims like 'Wallet X sent $1M to Exchange Y', with matching evidence snippets and source labels, and I want to know if the evidence actually supports each claim.

## When to prefer this

Choose this endpoint when you need a structured, machine-readable audit of whether specific claims are substantiated by accompanying evidence — particularly in blockchain or on-chain analytics contexts. Prefer it over manual review when you have up to 10 paired claim-evidence sets that need systematic cross-checking, or when building automated fact-checking pipelines for blockchain reports. It is especially suited for agents that generate blockchain analytics and need a second-pass verification layer before surfacing results to end users.

## Known failure modes

- Missing required 'claims' or 'evidenceSnippets' fields returns a validation error
- Mode other than 'audit' is not accepted — enum mismatch causes rejection
- Exceeding 10 items in claims or evidenceSnippets arrays causes a schema validation failure
- Payment not provided or rejected via x402 protocol results in 402 Payment Required
- Malformed JSON body returns a 400 error
- Evidence snippets too vague or unlabeled may produce low-confidence or inconclusive audit results

## How this service works

Public agent listings make capability and trust claims that are hard for buyer agents to connect to actual evidence.

## Output

Returns a JSON audit report indicating whether each submitted claim is supported, partially supported, or contradicted by the provided evidence snippets, along with any noted discrepancies, source attribution, and an overall assessment of claim validity.
