# OnchainPulse ISO Receipt — On-Chain Settlement to ISO 20022 Credit Notification

> OnchainPulse ISO Receipt — On-Chain Settlement to ISO 20022 Credit Notification is a paid API for AI agents from onchainpulse.theaslangroupllc.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Converts an EVM transaction hash into a bank-reconcilable ISO 20022 camt.054-style credit notification (XML + JSON) with a deterministic evidence bundle (canonical SHA-256 hashes) and an Ed25519 signature, covering ERC-20 transfers on 11 EVM chains.

## 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 onchainpulse-iso-receipt-on-chain-settlement-to-iso-20022-credit-0e432e44
```

Example prompt: Turn this Base chain transaction hash 0xabc123... into a bank-reconcilable ISO 20022 camt.054 receipt, with the evidence bundle and Ed25519 signature, from my perspective as address 0xdef456....

## When to prefer this

Choose this endpoint when you need a bank-reconcilable, audit-grade receipt for an on-chain ERC-20 or USDC settlement — especially for ISO 20022 compliance workflows, accounting reconciliation, or verifiable evidence bundles. Prefer it over generic blockchain explorers when you need a structured, signed, deterministic document rather than raw chain data. Ideal for x402 payment receipts on Base and other EVM chains.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction not found on the specified chain
- Chain parameter references an unsupported network (only 11 EVM chains covered)
- Transaction is not an ERC-20 transfer (non-ERC-20 txs may not be supported)
- Perspective address not involved in the transaction may return empty or partial data
- Network timeout when fetching on-chain data

## How this service works

Bank-reconcilable receipt for any on-chain settlement: turn a transaction hash into an ISO 20022 camt.054-style credit notification (XML + JSON), a deterministic evidence bundle with canonical SHA-256 hashes, and an Ed25519 signature anyone can verify without an API key at /verify.html. Same tx always yields a byte-identical bundle. Covers ERC-20 transfers on 11 EVM chains and SPL transfers on Solana (incl. x402 USDC settlements). Params: tx (required), chain (default base), perspective.

## Output

Returns a byte-identical (deterministic) bundle containing: an ISO 20022 camt.054-style credit notification in both XML and JSON formats, a canonical SHA-256 hash of the evidence bundle, and an Ed25519 signature verifiable without an API key at /verify.html. The same transaction hash always yields the same byte-for-byte output.
