## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability powerboy856-x402-tools-json-to-csv-converter-672bb9be -d '<json body>'
```

Example prompt: Convert this JSON array of up to 200 sales records into a CSV using a comma delimiter and make sure any spreadsheet formulas in the values are protected: [{"name":"Ada","score":98},{"name":"Linus","score":95}].

## When to prefer this

Choose this endpoint when you need a deterministic, auditable JSON-to-CSV conversion with a built-in SHA-256 integrity digest and spreadsheet-formula injection protection, and you want per-call micropayment pricing in USDC rather than a subscription. Ideal for agents that process up to 200 flat JSON records at a time and need comma, semicolon, or tab delimiters.

## Known failure modes

- Empty or missing `rows` array returns a validation error
- More than 200 items in `rows` exceeds the maxItems limit and is rejected
- Non-flat objects with nested arrays or objects fail schema validation
- Invalid delimiter value (not comma, semicolon, or tab) returns a schema error
- Payment failure or insufficient USDC balance results in a 402 response before processing

## How this service works

Small, deterministic API tools paid per call with USDC on Base through x402.

## Output

Returns a JSON object with: `ok` (boolean success flag), `csv` (the full CSV string with CRLF line endings), `sha256` (hex digest of the CSV for integrity verification), `columns` (array of column header names), and `rowCount` (number of data rows produced).
