Welcome to MeterGate, the API marketplace for businesses.

Buy interfaces from other companies here and pay only for the calls you actually make. You decide how much a key may spend at most.

MeterGate has just launched. Until billing starts, every call is free. We announce the date by email at least 14 days in advance.

Spending cap

A cap that takes effect before the call

For each key you decide how much it may spend in a period. Once the cap is reached, the next call is simply not executed, and no invoice arises for it. Every response tells you how much is left, so your program can stop in time.

This applies to every program that works with the key, including an AI agent that buys on its own. You connect it directly through our MCP server. For developers & agents

This is what the response at the cap looks like (a real example from this installation):

HTTP/1.1 402 Payment Required
Retry-After: 1203164
{
  "error": "budget_exceeded",
  "retryable": true,
  "retry_at": "2026-10-31T23:00:00.000Z",
  "self_service": null,
  "human_action": "Ask the account owner to raise the key budget.",
  "action_url": "https://metergate.dev/keys",
  "request_id": "MG-33JK-S7MN",
  "limit_cents": 5000,
  "spent_cents": 5000
}

Invoice

An invoice your bookkeeping can work with

Instead of many foreign receipts you receive one German invoice per provider from us, from which you can reclaim the VAT. It comes as an e-invoice that any accounting software can read, and for each product it states how many calls were billed and at what price. From 2028 this format is mandatory in Germany; with us it is standard today.

Providers

For providers: 85 percent and not a single invoice to write

You list your interface and set the price per call. We handle the settlement with the buyers, and every month you receive a self-billed invoice for your 85 percent. The money goes directly to your own Stripe account.

Before a provider appears in the catalog, Stripe confirms their identity, and we check their VAT ID. Offer your API
