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 containing the filtered 'object' with only the requested keys, the number of keys matched ('key_count'), a schema identifier, a pass/fail status, and evidence metadata including whether data was retained (always false), an SHA-256 hash of the input, and the number of external calls made (always 0).
Example use cases
Trim API response before storage
“I got a huge JSON response from the user profile API — can you pick out just the 'id', 'email', and 'plan' keys from it so I only store what I need?”
Redact sensitive fields from payload
“Here's a raw JSON record with a bunch of fields. Keep only 'order_id', 'status', and 'total' and drop everything else — I don't want to forward the customer PII downstream.”
Prepare subset for display
“From this product JSON with dozens of properties, extract just 'name', 'price', and 'thumbnail_url' — those are the only three I need to render the card in the UI.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-object-pick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call, no-signup utility to deterministically pick specific keys from a JSON object, especially in agent pipelines where verifiable, tamper-evident processing (SHA-256 evidence hash, no data retention) is required. Ideal for agents that need to filter API responses, reduce payload size before storage, or redact fields before forwarding data to downstream systems.
Side effects
- Requested keys not present in the object — result object will be empty or partial with key_count of 0
- Object exceeds 128 properties limit — request rejected
- Keys array exceeds 256 items — request rejected
- Malformed or non-object input — validation error returned
- Payment failure via x402 — 402 response before processing begins
