# Delx Commerce — JSON Object Rename Keys

> Delx Commerce — JSON Object Rename Keys is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Renames the keys of a JSON object according to a provided key mapping, returning the transformed object with collision tracking.

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 delx-commerce-json-object-rename-keys-faa9d0d6 -d '<json body>'
```

Example prompt: Rename the keys in this JSON object — change 'first_name' to 'firstName' and 'last_name' to 'lastName': {"first_name": "Ada", "last_name": "Lovelace", "id": 1}.

## When to prefer this

Choose this endpoint when you need a lightweight, verifiable, pay-per-use key renaming operation on a JSON object without signing up for a service or managing API keys. Ideal for AI agents that need to normalize field names between schemas on the fly, especially when auditability (SHA256 evidence, no-retention guarantee) matters. Prefer over custom code when operating in a stateless agent pipeline that already uses USDC/x402 micropayments.

## Known failure modes

- Object or mapping exceeds 128 properties — request rejected
- Invalid JSON structure in object or mapping fields — parse error
- Key collision when two source keys map to the same target key — reported in collisions array
- Payment failure or insufficient USDC balance — 402 response before processing
- Malformed request body — missing required fields returns error

## How this service works

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

## Output

Returns the input object with keys renamed according to the mapping, a list of any key collisions that occurred during renaming, a status field ('pass'), an evidence block confirming no data retention and including the SHA256 hash of the input, and a schema identifier for the operation.
