AISP Agent Skill
Agent Inference Sharing Protocol (AISP) lets agents rent idle DIEM/Venice API capacity via USDC escrow. Providers list capped API keys; agents fund and receive keys automatically.
Architecture
Agent: fund() → Backend sees Funded event → Key released → Agent uses Venice API
Provider: list() → Agent funds → Term expires → settle() → Provider paid (99%, 1% fee)
Agent Workflow (Renting)
- Listings from backend:
GET /api/listings
- Approve USDC if needed (contract spends on
fund)
- Fund on-chain:
contract.fund(listingId, termDays, diemAmount) → returns rentalId
- Get key:
POST /api/key/{rentalId} with signed message diem-marketplace:get-key:{rentalId}:{timestamp}
- Use
apiKey with Venice API until expiresAt (Unix timestamp)
SDK (Agent)
import { DiemAgent } from "diem-marketplace-sdk";
const agent = new DiemAgent({
signer: wallet,
contractAddress: "0x...",
backendUrl: "https://diem-marketplace-backend.fly.dev",
usdcAddress: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
});
const listings = await agent.getListings();
const { apiKey, expiresAt } = await agent.rent(
listings[0].listingId,
termDays,
ethers.parseUnits(diemAmount, 6)
);
Provider Workflow (Listing)
- Create listing on-chain:
contract.list(pricePerDay, termDays, diemMin, diemMax) → listingId
- Store key on backend:
POST /api/keys with { listingId, apiKey, signature, timestamp }
- Message:
diem-marketplace:store-key:{listingId}:{timestamp}
- Settle when rental expires:
contract.settle(rentalId) → provider receives 99% (1% protocol fee)
SDK (Provider)
import { DiemProvider } from "diem-marketplace-sdk";
const provider = new DiemProvider({
signer: wallet,
contractAddress: "0x...",
backendUrl: "https://diem-marketplace-backend.fly.dev",
usdcAddress: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
});
const listingId = await provider.createListing({
pricePerDay: ethers.parseUnits("0.80", 6),
termDays: 30,
diemMin: ethers.parseUnits("1000", 6),
diemMax: ethers.parseUnits("4000", 6),
apiKey: "vn-scoped-...",
});

Signatures
All backend requests requiring auth use EIP-191 signing:
getKey: diem-marketplace:get-key:{rentalId}:{timestamp}storeKey: diem-marketplace:store-key:{listingId}:{timestamp}balance: apiKey in body (no signature)
Contract (Base)
- Chain: Base (8453)
- Mainnet:
0xeeDa7657f2018b3b71B444b7ca2D8dE91b3B08f3
- USDC:
0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
Security & Signing
- Use an external signer or hardware wallet; never paste raw private keys.
- Require explicit user confirmation before fund transfers or credential usage.
- Venice API keys must be scoped (inference-only), revocable, and minimal for escrow.
Notes
- Venice API keys must be inference-only (not admin)
- 1% protocol fee deducted at settlement
