Spiral gives your agent every AI tool through one API key and one balance. Send a provider, a tool and its input; Spiral prices the run before it starts, runs it on the provider and charges the measured usage.

Quickstart

Connect your agent

Add the hosted MCP server to Claude Code, Codex, Cursor or VS Code.

API reference

Every endpoint, with its request and response.

Runs and pricing

How to work out a run’s price, and how it is held and charged.
