## 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 x402-agent-toolkit-json-transform-c81c9cf2 -d '<json body>'
```

Example prompt: Transform this JSON string '{"name":"Alice","score":42}' using the 'flatten' operation — pay the $0.01 USDC fee and return the result.

## When to prefer this

Choose this endpoint when you need deterministic, LLM-free JSON transformation as a paid utility — especially in automated agent workflows where you want predictable computation billed per-call in USDC on Base or Solana via x402 protocol.

## Known failure modes

- Missing required field 'data' or 'operation' returns validation error
- Invalid JSON string in 'data' field causes parse failure
- Unknown or unsupported 'operation' value returns error
- Payment not completed or rejected causes 402 Payment Required
- Malformed params object causes operation to fail or return unexpected output

## How this service works

Paid utility endpoints for AI agents. Pay with USDC on Base or Solana. Pure computation, no LLM dependency.

## Output

Returns a JSON object containing the result of the specified transformation operation applied to the input JSON data string. The structure of the response object depends on the operation performed.
