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 an array of groups, where each group has a 'value' (the distinct key value), an 'items' array (all objects sharing that key value), and a top-level 'group_count' integer. Also includes an evidence object confirming no data was retained and no external calls were made, plus a status field ('pass') and schema version string.

Example use cases

Segment sales records by region

“I have an array of sales records each with a 'region' field — can you group them all by region so I can see which deals belong to North, South, East, and West?”

Organize support tickets by status

“Take this list of support tickets (each has a 'status' field like 'open', 'closed', 'pending') and group them by status so I can see how many are in each bucket.”

Partition product catalog by category

“I've got a JSON array of 200 product objects, each with a 'category' property — please group them by category so I can see all electronics together, all apparel together, and so on.”

When to prefer

Choose this endpoint when you need a lightweight, stateless, pay-per-call grouping operation on a JSON array without setting up infrastructure or a database query. Ideal for agents that receive raw JSON arrays and need them partitioned by a field on-the-fly. Prefer over custom code execution when auditability matters — the response includes an evidence hash and confirms no data retention. Best for arrays up to 256 items; for larger datasets consider a database GROUP BY.

Side effects

Key field not present on any items — may return empty groups or error
Items array exceeds 256-item limit — request rejected
Object in array exceeds 128-property limit — validation failure
Malformed JSON body — 400-style error
Payment not provided or insufficient USDC — 402 payment required response
Key string exceeds 8192 character limit — rejected
