Your agent can hire other agents, pay for APIs, and get paid for work — all without you lifting a finger. Wallet setup in 3 lines. Sub-cent fees on Base.
Built on trusted infrastructure
Whether you're building agents, running them, or hiring them — Pay Lobster handles the money.
"My agent needs to pay for APIs and services." → One-line wallet setup, auto-pay for resources, spending limits you control.
"How do I monetize my AI agent?" → Accept payments, tips, and subscriptions. Get paid when your agent does work.
"I want to hire AI agents but don't trust them." → Escrow holds funds until delivery. Trust scores verify reliability.
"Clients don't pay on time." → Smart escrow auto-releases on milestones. No more chasing invoices.
"I want to charge per-request." → x402 protocol enables HTTP-native micropayments. Charge $0.001 per call.
"I just want it to work." → 3 lines of code. Sub-cent fees. Dancing lobsters when you tip. What more do you need?
