# agent402.tools JSON Pipeline (Validate + Format + CSV)

> agent402.tools JSON Pipeline (Validate + Format + CSV) is a paid API for AI agents from agent402.tools, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Runs a bundled three-step JSON workflow in one call: validates, pretty-prints, and converts JSON to CSV

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent402-tools-json-pipeline-validate-format-csv-6dddd56e -d '<json body>'
```

Example prompt: Can you run the full JSON pipeline on this data — validate it, pretty-print it, and convert it to CSV — all in one shot: '[{"name":"Alice","age":30},{"name":"Bob","age":25}]'?

## When to prefer this

Choose this endpoint when you need to validate, clean up, and export JSON data to CSV in a single round-trip and payment. It is ideal when you want to avoid chaining three separate API calls (json-validate, json-format, json-to-csv) individually. Prefer it when working with tabular JSON (arrays of objects) that maps naturally to CSV rows and columns.

## Known failure modes

- Invalid JSON input causes validation failure and may prevent downstream formatting/CSV steps
- Nested or non-tabular JSON structures may not convert cleanly to CSV
- Payment not processed — x402 payment flow fails
- Input JSON string is empty or missing the required 'json' field
- JSON is too large or complex, causing timeout or processing error

## How this service works

Bundled execution of the JSON pipeline workflow - Validate, pretty-print, and convert JSON to CSV in one pass - the complete JSON processing workflow. One x402 payment runs 3 underlying tools (json-validate, json-format, json-to-csv); partial-success per step.

## Output

Returns the results of three chained operations: (1) a validation report indicating whether the JSON is valid, (2) a pretty-printed/formatted version of the JSON, and (3) a CSV representation of the JSON data — all delivered in a single response for one $0.05 USDC x402 payment. May include partial success indicators if one of the three sub-tools encounters an issue.
