How this service works
Pluck a key from a list of objects. Call when you extract IDs/fields from agent-held JSON arrays. Returns values list and key for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a JSON object containing the specified key and a flat array of all the values found under that key across the input list of objects. Missing keys in individual items may yield nulls or be omitted depending on implementation.
Example use cases
Extract IDs from API response
“I have this JSON array of order objects from our API response — can you pluck out just the 'orderId' field from each one so I have a clean list of IDs to work with?”
Collect emails from user records
“Here's a list of user records I'm holding. Pull out the 'email' field from every object so I can get a flat list of all the email addresses.”
Gather product prices for comparison
“I've got an array of product JSON objects. Extract the 'price' field from each item so I can see all the prices in one list.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/pluckWhen to prefer
Choose this endpoint when you already have a JSON array in memory and need to extract a single field's values into a flat list without writing custom mapping logic. It is ideal for lightweight, stateless field extraction in agentic pipelines where spinning up code execution is overkill. Prefer it over general-purpose code execution when the operation is purely a projection of one key across objects and you want a fast, cheap ($0.001 USDC), no-side-effect utility call.
Side effects
- Key not found in any object — returns an empty list
- Items field is not an array — validation error
- Key field is empty or missing — bad request error
- Malformed JSON in items array — parse error
- Payment failure via x402 — 402 response, no result returned
