How this service works
Pay-per-call API for AI agents: turn any public web page or PDF into clean, LLM-ready Markdown. $0.002 per call in USDC on Base via x402. No API key, no signup.
Output
Returns a JSON object containing the operation name ('json2csv'), an array of column names, the number of rows converted, the resulting CSV text as a string, elapsed processing time in milliseconds, and any validation errors encountered.
Example use cases
Prepare API data for spreadsheet
“I got a JSON response from an API with a list of orders — can you convert it to CSV so I can open it in Excel? Here's the JSON: [{"order_id":1,"product":"widget","qty":5},{"order_id":2,"product":"gadget","qty":3}]”
Data pipeline format conversion
“I need to transform this JSON dataset into CSV format using a semicolon as the delimiter so my downstream ETL tool can ingest it: [{"country":"US","sales":1200},{"country":"UK","sales":850}]”
Validate and flatten JSON records
“Can you convert this JSON to CSV and let me know if there are any errors or inconsistencies in the structure? Here's the data: [{"user":"carol","score":88},{"user":"dave","score":72}]”

Use this endpoint when you need a fast, pay-per-call, no-signup conversion of JSON (or other structured formats) to CSV text — particularly in agentic workflows where you want to avoid managing API keys or subscriptions. Ideal for one-off data pipeline steps, agent-driven ETL tasks, or when preparing JSON API responses for spreadsheet consumption.
