REST · MCP

Small, sharp APIs for developers and AI agents.

One key for every API. Prepaid credits that never expire. Plug them into your code or connect them to your AI agent as MCP tools.

APIs

Compliant per diems in one call: official US GSA, German BMF and UK HMRC rates, with a trip calculator that applies each country's rules.

1. Buy credits

Pay once with card via Stripe and get your key instantly. No subscription.

2. Call any API

Send X-API-Key with each request. Every call is deducted from one balance.

3. Or go agent-native

Each API is also an MCP server.
