How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

Output

Returns a JSON object with ok:true, the tool name, and a result object containing: the full CSV string (with headers and rows, RFC 4180-compliant quoting), the number of data rows, and an array of column names (using dot-notation for flattened nested keys).

Example use cases

Export API results to spreadsheet

“I have this JSON array from an API response and I need to turn it into a CSV so I can open it in Excel — please flatten any nested objects and use a comma as the delimiter.”

Generate tab-separated data file

“Take this list of JSON objects and convert them to a tab-separated values file — I need it as TSV so I can paste it directly into a Google Sheet.”

Flatten and export nested JSON records

“I've got nested JSON records with sub-objects like address.city and address.zip — can you flatten them and convert the whole array to a semicolon-delimited CSV?”

When to prefer

Choose this endpoint when you need a quick, serverless, no-account JSON-to-CSV conversion with optional nested-key flattening and configurable delimiters, and you want to pay per call in USDC without API key management. Prefer it over custom code or heavyweight ETL services for simple one-off or agent-driven tabular export tasks.

Side effects

Input is not a valid JSON array of objects — returns error
JSON string cannot be parsed — returns parse error
Unsupported delimiter value — returns validation error
Payment not included or insufficient USDC — returns 402 Payment Required
Empty array input — may return headers-only CSV with zero rows
