// express-402-paid-endpoint.js
|
|
//
|
|
// Drop-in example: a paid `/v1/inference` endpoint that charges $0.0125
|
|
// in USDC.e per call via AERE402 settlement on Chain 2800.
|
|
//
|
|
// Run:
|
|
// yarn add express @aere/sdk-js ethers
|
|
// FACILITATOR=0x... PAYEE=0x... PROVIDER_PRIVATE_KEY=0x... node express-402-paid-endpoint.js
|
|
//
|
|
// Then the agent-side does:
|
|
// 1. curl http://localhost:3000/v1/inference
|
|
// → 402 with X-AERE402-Quote JSON header
|
|
// 2. agent EIP-712-signs the quote using its registered signing key
|
|
// 3. curl -H "X-AERE402-Sig: 0x.." -H "X-AERE402-AgentId: 1234" \
|
|
// -H "X-AERE402-Quote: <original-quote-json>" \
|
|
// http://localhost:3000/v1/inference
|
|
// → 200 with the actual inference output, X-AERE402-TxHash header set
