# Delx Commerce — JSON Object Omit

> Delx Commerce — JSON Object Omit 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).

Removes specified keys from a JSON object and returns the filtered result with verifiable evidence of in-memory-only processing.

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-omit-65ca34c3 -d '<json body>'
```

Example prompt: Take this JSON object {"id":1,"name":"Alice","password":"secret","token":"abc123"} and remove the keys 'password' and 'token' from it, giving me back the cleaned object.

## When to prefer this

Choose this endpoint when you need a verifiable, auditable, pay-per-call transformation that removes keys from a JSON object without any server-side data retention — especially useful in privacy-sensitive or compliance-driven pipelines where you need cryptographic proof (SHA-256 input hash) that the operation was performed in-memory only. Prefer this over a custom code snippet when you need an immutable audit trail or are operating in an agent workflow that bills per operation.

## Known failure modes

- Object exceeds 128 properties limit — request rejected
- Keys array exceeds 256 items or individual key exceeds 8192 characters — validation error
- Malformed JSON object in request body — parse error
- Payment failure via x402 protocol — 402 response with payment details
- Key not present in object — silently ignored, object returned as-is

## 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 the specified keys removed, along with a count of keys that were omitted, the SHA-256 hash of the input for auditability, confirmation that no data was retained or sent to external systems, and a status of 'pass' indicating successful processing.
