Production APIs
agent-ready
One key
every model, every API,
pay per call
Top up once. Spend a fraction of a cent per call on any provider we route to. No min commit, no per-provider account, no overage trauma.
Plug-and-play
no glue code
Cross-API skills — each capability hides routing, auth, retries, and schema-translation behind a single endpoint. Drop one ID in your tool list, spare handles the rest.
Two steps
and your agent calls a real API
One skill that hands your AI the live spare tool catalog. Works with Claude Code, Cursor, Codex CLI, Gemini CLI, and any MCP-compatible harness.
Type /spareai followed by what you want. The skill picks the right action, fills params, and routes through spare — usage is metered to your key.
