AgentPayAPI
Risk-first infrastructure

Autonomous AI transactions.
Zero rogue exposure.

The Wallet-as-a-Service API built for AI agents.
Hard risk limits enforced at the infrastructure layer — not in your prompts.

Network-agnostic. Deploy on any chain:
Ethereum·Base·Polygon·Arbitrum·Optimism·Sepolia·Base Sepolia
500+ Devson the waitlist
7 Networks(5 mainnets and 2 testnets)
$0 Lostto Rogue Agent Activity

Risk blocks are enforced before signing. If the API blocks it, it never happened.

Your agent has a wallet. You keep the keys.

AgentPayAPI sits between your AI and the blockchain — enforcing your rules before any transaction is signed.

Your agent never sees the private key

Keys are generated and stored in isolated secure enclaves. Your AI gets a revocable API key — not cryptographic access. Even we can't extract the private key.

[Non-custodial]

One toggle to stop everything

If your agent starts behaving unexpectedly, a single dashboard toggle revokes its API access instantly. No draining funds. No custom logic. Just off.

[Real-time control]

Any EVM network, not just BASE

Deploy your agent on Ethereum, Polygon, Arbitrum, Optimism, Base, or any EVM-compatible chain. One API, every supported EVM chain.

[Network-agnostic]

What are developers building with AgentPayAPI?

DeFi Trading Agents

Give your LLM-based trading bot a wallet with hard daily loss limits. It can trade — but it can't blow up your account.

Autonomous Purchasing Agents

Let your AI agent pay for API calls, cloud resources, or on-chain services — capped to exactly what you authorize per transaction.

Web3 Game Agents

Build NPCs or AI opponents that hold and spend in-game assets on-chain, with limits that keep your game economy intact.

AgentPayAPI vs. Coinbase Agentic Wallets

While Coinbase provides excellent tools for enabling agents to transact, AgentPayAPI is built from the ground up to contain and control them.

AgentPayAPICoinbase Agentic Wallets
Risk enforcement layer Infrastructure⚠️ Application (your code)
Kill switch Native, 1-click Custom implementation
Agent key access API key only⚠️ Direct SDK signing
Network support Any network⚠️ BASE only
Prompt injection protection Bypassing impossible Relies on prompt logic
Non-custodial Yes Yes

Coinbase is excellent infrastructure. AgentPayAPI is the safety layer your agents need on top of it — on any chain.

Simple, secure integration

Give your agent an API key, not a private key. The AgentPayAPI handles the cryptography, risk checks, and transaction broadcasting.

  • 1. Agent requests transaction via API
  • 2. API evaluates your risk rules (order size, daily volume, network)
  • 3a. Limits OK → secure enclave signs and broadcasts
  • 🛑3b. Limits exceeded → rejected before signing. Nothing hits the chain.
POST /api/v1/transact
// 1. Give your agent an API key — not a private keyconst response = await fetch('https://api.agentpay.io/v1/transact', {method: 'POST',headers: {'Authorization': `Bearer ${AGENT_API_KEY}`,'Content-Type': 'application/json'},body: JSON.stringify({to: '0x742d35Cc6634C0532925a3b844Bc454e4438f44e',value: '0.05',network: 'ethereum',   // ← any supported network, not just basememo: 'pay-for-inference-job-441'})})// 2. AgentPayAPI checks your risk rules before signing// 3. If limits are OK → enclave signs and broadcasts// 4. If limits exceeded → rejected before it hits the chainconst result = await response.json()// { "success": true, "txHash": "0xabc...", "riskCheck": "passed" }
