A short, production-oriented path for developers who already have a useful API, tool, workflow, or agent capability and want it reachable by AI agents.
Railway is suitable for long-running APIs, workers, MCP servers, background jobs, and databases. PAL uses a referral link below; new referred users receive Railway credits while PAL may earn cash commission on qualifying spend.

Check uptime, deterministic inputs/outputs, payment metadata, cold-start latency, and whether an unpaid request reliably returns the expected challenge. PAL's marketplace page exposes working examples and paid commerce tools.
