How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

Output

Returns a JSON object containing a 'groups' array, where each element has a 'key' (the distinct value of the grouped field) and an 'items' array listing all original objects that share that key value.

Example use cases

Group product inventory by category

“I have a list of products and I need them grouped by their 'category' field — here's the array: [{"name":"Widget A","category":"hardware"},{"name":"Widget B","category":"software"},{"name":"Widget C","category":"hardware"}]”

Segment user events by type

“Take these user event logs and group them by the 'eventType' field so I can see all clicks together, all purchases together, etc.: [{"user":"alice","eventType":"click"},{"user":"bob","eventType":"purchase"},{"user":"alice","eventType":"purchase"}]”

Partition survey responses by answer

“I've got a bunch of survey responses and I want them grouped by the 'rating' field — can you partition this array: [{"id":1,"rating":"positive"},{"id":2,"rating":"negative"},{"id":3,"rating":"positive"},{"id":4,"rating":"neutral"}]?”

Technical details

Endpoint

POSThttps://x402-agent.kariguetoazul.workers.dev/api/json/array-group-by?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a simple, paid, on-demand group-by operation on a JSON array without setting up server-side infrastructure. Ideal for agents that need to partition up to 1000 records by a single field key in real time as part of an automated workflow, especially when integrated with x402 micropayment flows on Cloudflare Workers.

Side effects

Missing or empty 'key' field returns an error or ungrouped result
Array items that lack the specified key field may be grouped under an undefined/null bucket
Arrays exceeding 1000 items are rejected due to maxItems constraint
Malformed JSON in the values array causes a parsing error
Payment failure (402) if USDC balance is insufficient for the $0.001 per-call fee
