Overview

What is Data Formatter?

Data Formatter converts CSV, XML, or Markdown input into JSON or HTML output using Claude AI. Part of the x402 micropayment task market, it offers a paid endpoint ($0.005 USDC per call on Base mainnet) and a free trial endpoint with 32KB input limit. Designed for MCP-compatible agents and Claude Desktop.

How to use Data Formatter?

Install via Smithery or connect directly to the SSE endpoint (https://project-formatter-production.up.railway.app/sse) for the MCP tool format_data. Alternatively, send HTTP POST requests to /v1/format (paid, requires x402 payment header) or /v1/format/trial (free). Specify input, from_format, and to_format parameters; optionally add validate=true on the paid endpoint.

Frequently asked questions

1

What does Data Formatter do that alternatives don't?

Data Formatter uses Claude AI for intelligent conversion and optionally validates the structural integrity of the output, all on a pay‑per‑call basis.

2

What are the runtime or payment requirements?

Paid calls require a valid x402 payment header with $0.005 USDC on Base mainnet (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`). The free trial endpoint needs no payment.

3

Where does my data go during conversion?

Input data is sent to the live service at `https://project-formatter-production.up.railway.app` and is processed server‑side. The README does not specify data retention or privacy guarantees.

4

What transports and authentication are available?

The server supports HTTP REST (paid: `/v1/format` with x402 payment header; trial: `/v1/format/trial`) and MCP SSE transport (`/sse`). The paid endpoint requires cryptographic payment authentication; the trial endpoint has no auth.

5

Are there any known limits?

The free trial endpoint is limited to 32KB input and does not support the `?validate=true` parameter. The paid endpoint has no documented input size limit in the README.
