AmanChain x402 for agents AmanChain x402 for agentsImage generation, LLM chat, web research, live crypto prices, wallet portfolios, token audits, market reports — every call paid per use with x402, settled in AMAN inside a quantum-resistant proof-of-work chain or in real USDC on Base. No accounts. No API keys. No subscriptions. No chargebacks.
Built for machine-to-machine commerce from day one — not a web API bolted onto crypto.
Standard x402: the server answers with HTTP 402 + a machine-readable price. Pay it, replay the request with the proof, get the result. Any x402 client library works in minutes.
Native AMAN: an agent_invoke transaction mined by consensus — receipts live in blocks, verifiable forever. Or USDC on Base via EIP-3009 through the Coinbase facilitator — gasless for the payer.
Node-operated services execute inside the block rules — the same input returns the same output, and every execution is auditable on-chain. No silent behavior changes behind your back.
If a paid execution fails, the node issues an automatic on-chain refund of the exact price. Agent money is never stuck — the guarantee is consensus, not a promise.
Every transaction carries a mandatory ML-DSA-87 (NIST FIPS 204) signature on top of Ed25519. Your payment history is protected against harvest-now-decrypt-later attacks.
No fiat on-ramp needed: AmanChain is real proof-of-work — a CPU mines ~40 AMAN in seconds (~3s blocks). Agents can bootstrap their own operating budget.
Plain HTTP. If your runtime can POST JSON, it can pay and get paid.
# any service — the canonical URL returns the quote curl -s -X POST https://amanchain-relay.gitajhd.workers.dev/api/x402/aman-crypto-price \ -H 'Content-Type: application/json' -d '{"request":"BTC"}' # → HTTP 402 + accepts[] (price, payTo, two rails)
# rail A — native AMAN (on-chain, quantum-safe): # sign an agent_invoke for the exact price, then broadcast: POST https://amanchain-relay.gitajhd.workers.dev/api/v1/tx → txId # rail B — USDC on Base (gasless EIP-3009): # send maxAmountRequired to the quoted payTo with the # X-PAYMENT header (standard x402 client libs do this)
# AMAN rail: re-POST with the payment txId curl -s -X POST https://amanchain-relay.gitajhd.workers.dev/api/x402/aman-crypto-price \ -H 'Content-Type: application/json' \ -d '{"request":"BTC","payment":{"txId":"<txid>"}}' # → paid:true + result + on-chain receipt (~3s blocks)
If the node accepts your payment and the execution fails, the node wallet signs an automatic refund transaction for the exact amount and the network mines it within seconds. The refund itself is stored with the settlement receipt so it can never double-pay. Priced services that require an input reject an empty one before charging — you cannot pay by mistake.

AmanChain implements it natively — payments are real mined transactions, not database rows.
Each 402 quote includes an accepts[] option with scheme:"exact", network:"base" — pay that exact amount (µUSDC) to the quoted payTo via EIP-3009 transferWithAuthorization, or use any standard x402 client (the Coinbase x402 fetch wrapper works as-is). The Coinbase facilitator verifies and settles; the node then executes and returns the result.
Mine it: AmanChain is SHA3-256 proof-of-work with ~3-second blocks — a laptop CPU earns ~40 AMAN in seconds via POST /api/mine. For production volume, buy AMAN on the built-in AMM (USDT/USDC/BTC/ETH/SOL/BNB pools) or bridge in.
The node auto-refunds the exact price on-chain within seconds, and the refund is recorded with the settlement receipt (no double-refunds possible). Services that require an input validate it before accepting payment.
Prices are fixed in AMAN and displayed in USD at the live on-chain AMM rate. The 402 quote is always the exact, current price — no surprise billing, no recurring charges, no rate limits beyond your balance.
