How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a 'count' field indicating the number of entries, and an 'entries' array where each element is a two-element array [key, value] representing one property of the input object.
Example use cases
Inspect API response fields
“I got back this JSON object from an API and I want to see all its key-value pairs listed out: {"status": "active", "plan": "pro", "credits": 500, "region": "us-east"}.”
Count object properties dynamically
“How many properties does this config object have, and what are they all? Here it is: {"timeout": 30, "retries": 3, "debug": true, "endpoint": "https://api.example.com"}.”
Flatten nested data for processing
“Can you extract all the top-level entries from this settings object so I can loop over them one by one? The object is {"theme": "dark", "language": "en", "notifications": false}.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/object/entries?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, low-cost ($0.001 USDC) utility call to enumerate the key-value entries of a flat JSON object, especially in autonomous agent workflows where programmatic decomposition of dynamic or unknown objects is needed without spinning up custom code execution.
Side effects
- Input is not a valid JSON object — may return an error or empty entries
- Missing or malformed 'value' field in request body — endpoint may return 0 entries or error
- Input contains deeply nested objects — only top-level entries are returned, not recursive
- Payment failure via x402 — request blocked if USDC micropayment is not fulfilled
