# Delx Commerce — JSON Object Lowercase Keys

> Delx Commerce — JSON Object Lowercase Keys is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Transforms all keys of a JSON object to lowercase, returning the modified object and any collision metadata, with verifiable in-memory processing and no data retention.

## Facts

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-lowercase-keys-3a6ed151 -d '<json body>'
```

Example prompt: Take this JSON object — {"UserID": 1, "FirstName": "Ada", "LastName": "Lovelace"} — and convert all its keys to lowercase so I get back {"userid": 1, "firstname": "Ada", "lastname": "Lovelace"} along with any key collision info.

## When to prefer this

Choose this endpoint when you need a trustless, pay-per-call, verifiable utility to lowercase JSON object keys without any account setup, and when auditability matters (input hash, no-retention evidence). Ideal for AI agents that process untrusted or inconsistent JSON payloads and need a deterministic, evidence-backed transformation at $0.001 per call.

## Known failure modes

- Object exceeds 128 properties — rejected with validation error
- Invalid or non-object input — schema validation failure
- Payment not completed via x402 — 402 Payment Required response
- Network timeout — request fails with no 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 with all keys lowercased, a list of any key collisions that occurred during the transformation, a SHA-256 hash of the input for verifiability, confirmation that no data was retained, the count of external calls made (always 0), and the operation status (pass/fail).
