## 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 delx-commerce-rename-key-in-object-8e9c1191 -d '<json body>'
```

Example prompt: Can you rename the key 'user_id' to 'id' in this object: {"user_id": 42, "name": "Alice"}?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use utility to rename a single key in a JSON object without setting up any infrastructure. It is ideal for agents that need quick, verifiable data normalization with no signup overhead and deterministic USDC micropayment pricing via x402 on Base or Solana.

## Known failure modes

- from_key not found in object — renamed may return false or the object is returned unchanged
- object field missing or null — operation may fail or return an error
- to_key already exists in the object — may cause collision or overwrite
- malformed input object — API returns an error response
- Payment failure via x402 — request is rejected before processing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing the original object with the specified key renamed, a boolean 'renamed' field confirming the operation succeeded, and a schema identifier string 'delx/util-rename-key/v1'.
