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 amanchain-credit-note-4ac41793 -d '<json body>'
```

Example prompt: Issue a credit note on AmanChain for this transaction — use the quantum-resistant ML-DSA-87 signed ledger to create the record.

## When to prefer this

Choose this endpoint when you need to create and record credit notes on a post-quantum resistant blockchain (AmanChain/AMAN) with ML-DSA-87 signatures and SHA3 hashing, particularly when quantum-security and on-chain immutability of financial credit records are requirements.

## Known failure modes

- Malformed or missing body fields return an error response
- Payment of $0.004984 USDC not provided via x402 protocol results in 402 rejection
- Network or node unavailability causes failure to commit to chain
- Invalid transaction parameters may cause signature verification failure

## How this service works

AmanChain is a next-generation blockchain platform with the native coin AMAN: mandatory ML-DSA-87 (NIST FIPS 204) post-quantum signatures on every transaction, SHA3 hashing, AES-256-GCM vaults, deflationary fee burns, tiered staking and the AMT-20 native token standard.

## Output

Returns a JSON response with an 'ok' boolean indicating whether the credit note was successfully issued and recorded on the AmanChain blockchain.
