How it works

One request, a price only when it succeeds

Call the endpoint
A plain GET request. Add free=1 for one free call per tool and IP address per day.
```
curl "https://api.ambolt.dev/v1/eu-vat-validate?vat=DK10150817&free=1"
```
Pay per call, or use MCP
Without free=1 the answer is 402 with the price. An x402 client pays in USDC on Base, Polygon or Solana and retries. MCP tools are free at 30 requests a minute.
Check the source
Every response names its source, licence and the time it was read. Invalid input and unavailable sources are never charged.
