# AmanChain x402 Blockchain Interaction

> AmanChain x402 Blockchain Interaction is a paid API for AI agents from amanchain-relay.gitajhd.workers.dev, paid per call via x402, $0.001244/call, status unknown (last checked 2026-09-15).

Executes transactions and interactions on the AmanChain quantum-resistant blockchain via the x402 payment protocol, enabling post-quantum-secured on-chain operations with AMAN native coin

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-x402-blockchain-interaction-69240d64 -d '<json body>'
```

Example prompt: Submit a transaction on AmanChain to send 50 AMAN to address amanchain:0xABCDEF1234567890 — it needs to be signed with ML-DSA-87 post-quantum signatures and broadcast through the x402 relay.

## When to prefer this

Choose this endpoint when you need to submit, broadcast, or execute transactions on the AmanChain blockchain specifically, particularly when post-quantum cryptographic security (ML-DSA-87 / NIST FIPS 204) is required. Prefer this over generic blockchain APIs when working with AMAN native coin, AMT-20 tokens, or AmanChain-specific features like tiered staking, deflationary fee burns, or AES-256-GCM vaults. Ideal for agents requiring quantum-resistant transaction signing rather than classical ECDSA-based chains.

## Known failure modes

- Invalid or malformed x402 payment header — returns authentication/payment error
- Insufficient AMAN balance for transaction fee — returns insufficient funds error
- Invalid ML-DSA-87 signature format — returns signature validation failure
- Network congestion causing transaction timeout — returns timeout or pending status
- Invalid recipient address format — returns address parsing error
- Nonce conflict or double-spend attempt — returns rejected transaction error

## 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 containing the transaction hash, block confirmation status, fee burn amount, and on-chain receipt details for the submitted AmanChain transaction, signed with ML-DSA-87 post-quantum signatures and hashed with SHA3.
