# Vealth Cross-Verify (CDP-settled)

> Vealth Cross-Verify (CDP-settled) is a paid API for AI agents from vealth.net, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Neutrally verifies a public protocol claim (e.g. for litcoin or regen) against that protocol's own on-chain or API source, against a fixed set of trusted hosts.

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 vealth-cross-verify-cdp-settled-935760ed -d '<json body>'
```

Example prompt: Cross-verify this Regen Ledger ecological credit claim — protocol is 'regen', claim_ref is 'C-123456', and I expect the credit_status to be 'active' and issuer to be 'Regen Network Development Inc' — check it against Regen's own on-chain source and tell me if the claim checks out.

## When to prefer this

Use this endpoint when you need a neutral, fixed-host cross-check of a specific protocol claim against that protocol's own authoritative source — particularly for well-known protocols like regen or litcoin. Prefer this over generic web scrapers or self-reported data when the integrity of a blockchain or ecological credit claim matters and you want an independent, CDP-settled verification that cannot be redirected to an attacker-controlled target.

## Known failure modes

- Protocol not in the fixed allow-list — endpoint refuses to follow arbitrary redirects or check unknown hosts
- claim_ref not found on the target protocol's ledger or API
- On-chain source temporarily unavailable, resulting in a timeout or upstream error
- Malformed expect object causing schema validation failure
- Payment not settled via CDP x402, resulting in 402 rejection before verification runs

## How this service works

Cross-Verify (CDP-settled mirror) — a neutral check of a public protocol claim (e.g. litcoin, regen) against its own on-chain / API source. Fixed hosts, no redirect follow: we cannot be pointed at an arbitrary target.

## Output

A structured verification result indicating whether the stated claim (identified by protocol and claim_ref) matches the data from the protocol's own on-chain or API source, including any discrepancies between the expected values and actual on-chain values.
