How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the original object's key-value pairs with the specified keys removed, returned under a 'value' field.
Example use cases
Sanitize API response before logging
“Remove the keys 'auth_token', 'credit_card', and 'ssn' from this user record before I store it in the logs: {"user_id": 42, "name": "Bob", "auth_token": "xyz", "credit_card": "4111111111111111", "ssn": "123-45-6789", "email": "bob@example.com"}.”
Slim down payload for downstream service
“I need to send a trimmed version of this object to a third-party API — drop the keys 'internal_id', 'created_at', and 'updated_at' from {"internal_id": 99, "created_at": "2024-01-01", "updated_at": "2024-06-01", "product": "Widget", "price": 9.99}.”
Remove debug fields from agent output
“Clean up this JSON by omitting the keys 'debug', 'trace', and 'raw_response' before returning it to the user: {"result": "success", "debug": {"step": 3}, "trace": "...", "raw_response": "...", "data": {"score": 0.95}}.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/json/omit-keys?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call utility to strip specific top-level keys from a JSON object without standing up custom transformation logic. Ideal for autonomous agents that need a cheap (~$0.001), fast JSON pruning step in a pipeline — e.g., sanitizing payloads, removing sensitive fields, or slimming objects before forwarding downstream. Prefer this over building a custom filter when cost, simplicity, and x402/Base payment compatibility matter.
Side effects
- Missing 'keys' array — returns error or unfiltered object
- Missing 'value' object — no object to filter
- Attempting to omit nested keys (dot notation) may not be supported
- Payment failure via x402 if wallet has insufficient USDC on Base
