Credit lines for AI agents

Your agents need to call paid APIs but have no wallets or funds. Borrow USDC.e from the vault, call any service, settle later.

Agent quickstart

Everything an agent needs to register, borrow, and start calling paid APIs. No admin approval required.

Read the integration guide

Fetch /llms.txt — it has every endpoint, request format, and code example your agent needs.

curl https://YOURSERVER/llms.txt

Register as an operator

Three API calls: get a nonce, sign it with your wallet, save a card via Stripe. The vault approves you on-chain.

              POST /api/auth/nonce     ← get message to sign
POST /api/register       ← create Stripe setup intent
POST /api/register/confirm ← card + signature → approved
            

Stripe test card: 4242 4242 4242 4242, any future expiry, any CVC. Use tok_visa as a shortcut for test mode.

Borrow USDC.e

Self-serve. No admin key needed. The vault enforces your credit limit on-chain ($0.50).

              POST /api/borrow
{"agentAddress": "0xYOUR_WALLET", "amount": "100000"}
# → $0.10 USDC.e sent to your wallet. Debt starts accruing.
            

Call any MPP service

Install the Tempo CLI. Your borrowed USDC.e pays for sessions and charges automatically.

              curl -fsSL https://tempo.xyz/install | bash
tempo wallet login

# Search the web ($0.005)
tempo request -X POST \
  --json '{"query":"AI agents","numResults":3}' \
  https://exa.mpp.tempo.xyz/search

# Ask an LLM ($0.001)
tempo request -X POST \
  --json '{"model":"meta-llama/llama-3.3-70b-instruct",
  "messages":[{"role":"user","content":"hello"}]}' \

Check debt and settle

Interest accrues per-second on-chain. Settle anytime from the dashboard or directly on-chain.

              GET /api/operator/0xYOUR_WALLET/debt
# → {"principal":"100000","interest":"2","total":"100002"}

# Settle: connect wallet on /dashboard → "Pay Debt"
# Or on-chain: USDC.e.approve(vault, total) + vault.settleDebt(you)
