When to choose POLYROB
You want goals chased, not chatted
Durable goals + autonomy loops that run unattended, survive restarts, and deliver — and an agent that evolves its own skills as it goes.
You want a crypto-native agent
A built-in wallet and x402 pay-per-request in USDC on Base — the agent pays for what it uses and can charge for its own work.
You're building an agent product
Multi-tenant isolation, metering + credits, and standard APIs (REST / OpenAI-compat / A2A) are in the core — ship a paid agent without a backend. Apache-2.0, self-hosted.
