Sandpi Platform

Build with coding agents

Run native coding agents in persistent workspaces. Start with a first Run, configure the tools it needs, then connect schedules and external events.

From API key to first result

Create an Environment, choose a harness Session, submit a Run and follow its output.

Quick start →

Each guide includes its API parameters, request bodies, responses and examples. Integrating an event source? Start with inbound webhooks.

The public Platform HTTP contract is authored in platform-openapi.json; the endpoint details and examples here come from that contract. For current BYOK behavior, read model connections. For Sandbox runtime pricing, credits and spending boundaries, read billing and budgets. Model usage is billed by your provider or gateway.
