# Sui Faucet > Provides test SUI on Testnet, Devnet, and operator-configured development networks through a proof-of-work HTTP API. Agents and CI integrations should start with the automation guide. Each payout requires a valid proof of work. Configure the API base URL explicitly; the documentation website and API can have different origins. ## Documentation - [Automation guide](/how-to-use.md): Networks, request fields, curl commands, and recovery limits. - [Proof-of-work specification](/pow-spec/pow-spec.md): Canonical proof computation, encoding, freshness, and conformance vectors.
