The GOBL API provides a hosted REST service for working with GOBL documents without needing to install or run any libraries locally. It’s ideal for integrations in any language. Base URL: 
https://gobl.dev/v0

​
Endpoints

The API is organized into three groups:

​
Quick Example

Build and validate an invoice in a single request: 
curl -X POST https://gobl.dev/v0/build \
  -H "Content-Type: application/json" \
  -d '{
    "data": {
      "$schema": "https://gobl.org/draft-0/bill/invoice",
      "series": "EXAMPLE",
      "currency": "USD",
      "issue_date": "2024-01-15",
      "supplier": {
        "name": "Seller Co.",
        "tax_id": { "country": "US" }
      },
      "customer": {
        "name": "Buyer Inc.",
        "tax_id": { "country": "US" }
      },
      "lines": [
        {
          "quantity": "1",
          "item": {
            "name": "Service",
            "price": "100.00"
          }
        }
      ]
    }
  }'
No authentication is required. The API is free to use.

MCP Server

An MCP (Model Context Protocol) server is also available for integrating GOBL with AI assistants like Claude. It exposes the same document operations plus tax reference data as MCP tools.
