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 sorted array under 'result.items', the key used for sorting under 'result.key', a status field ('pass'), and an evidence block with a SHA-256 hash of the input, a 'retained: false' flag confirming no data was stored, and an external_calls count of 0 confirming no third-party calls were made.
Example use cases
Sort product catalog by price
“I have a list of products as JSON objects and I need them sorted by the 'price' field from lowest to highest — can you do that?”
Order user records alphabetically
“Sort these user records by the 'last_name' field in ascending order so I can display them in alphabetical order in my app.”
Rank events by timestamp descending
“I've got a batch of event log objects and I need them sorted by the 'timestamp' field, newest first (descending), so I can show the most recent activity at the top.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-array-sort-by-key?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use, verifiable sort of a JSON array of objects by a named key without setting up any infrastructure or signing up for a service. It is ideal for AI agents operating autonomously that need deterministic, in-memory data transformations with cryptographic proof of non-retention. Prefer it over building sort logic inline when auditability and verifiable execution matter, or when calling from an agent that already handles x402 micropayments in USDC on Base or Solana.
Side effects
- Invalid or missing 'key' field — returns error if key is not a string or exceeds 8192 characters
- Array exceeds 256 items — request rejected due to maxItems constraint
- Object in array has more than 128 properties — rejected due to maxProperties constraint
- Key not present in array objects — may return unsorted or partially sorted results
- Malformed JSON input — request fails with parsing error
- Payment not provided or insufficient USDC — HTTP 402 returned before processing
