x402
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.

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.
Example use cases
Audit DeFi protocol parameters against chain state
“I need to verify a Litcoin protocol claim — protocol is 'litcoin', claim_ref is 'LTC-789012', and the documentation says total_supply should be 21000000 and current_block_height should be 850000. Can you cross-verify this against Litcoin's actual on-chain data and let me know if there are any discrepancies?”
Validate ecological credit issuance legitimacy
“We received a Regen Ledger credit claim from a vendor — protocol is 'regen', claim_ref is 'C-456789', and they're saying it was issued by 'Soil Carbon Initiative' with vintage_year '2023'. Please check this against Regen's own ledger to confirm the issuer and vintage match what's actually on-chain.”
Confirm blockchain claim trustworthiness for transactions
“Before we accept this as collateral, I need a neutral check on a public protocol claim — protocol is 'litcoin', claim_ref is 'UTXO-334455', and the claim states the balance is 5.25 BTC and the transaction_status is 'confirmed'. Cross-verify this against the actual Litcoin source and tell me if the claim is legitimate.”
Technical details
Endpoint
POSThttps://vealth.net/.well-known/vealth/cdp/cross-verifyWhen to prefer
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.
Side effects
- 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
