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.
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.
Cap every transaction
Set a maximum USD value per transaction. If your agent hallucinates a $50,000 trade, the API rejects it before it ever touches the chain. Hard limit. No exceptions.
[Infrastructure-level enforcement]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.
| AgentPayAPI | Coinbase 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.
