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 pastable-x402-csv-to-json-converter-e494d0fc
```

Example prompt: Can you convert this CSV string to JSON for me — 'name,city\nAda,London\nBob,Paris' — using a comma as the delimiter?

## When to prefer this

Use this endpoint when an agent needs to quickly parse a CSV string into JSON at runtime without standing up a local parser, especially in lightweight agent workflows on Base mainnet using x402 micropayments. Ideal for one-off conversions where importing a CSV library is impractical. Prefer this over general-purpose code execution if you want a deterministic, low-latency data transform for $0.02 USDC.

## Known failure modes

- Missing 'csv' query parameter returns an error
- Malformed CSV (mismatched quotes, inconsistent columns) may produce unexpected results
- Very large CSV strings may be truncated or rejected
- Wrong delimiter specified causes all data to land in a single column
- Payment failure via x402 (insufficient USDC balance) blocks the call

## How this service works

Pay-per-call utility APIs for agents: EVM helpers (checksum, unit conversion, keccak), data transforms (CSV to JSON, JSON diff, URL canonicalisation), text tools (hashing, JWT decode), and Bazaar market intelligence. x402 on Base mainnet.

## Output

Returns a JSON object containing a 'data' array of objects (one per CSV row, keyed by column headers), a 'rows' integer count of data rows, and a 'columns' array of column name strings.
