How this service works
$0.0002/MB. Group rows and aggregate — count, sum, avg, min, max — in one call. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
Returns grouped result rows where each row represents a unique combination of the grouping columns, along with the requested aggregate values (count, sum, avg, min, max) for the specified numeric columns. Billed at $0.0002/MB of input data with a 1¢ minimum via x402 micropayment; any overpaid amount is auto-credited.
Example use cases
E-commerce revenue rollup by category
“Take these order records and group them by product category, then compute the total revenue, average order value, and number of orders per category.”
Log file error rate by status code
“I have a list of server log entries with status codes and response times — can you group them by status code and give me the count and average response time for each?”
Monthly sales performance summary
“Group these transaction records by month and sales rep, and calculate the total sales amount, minimum deal size, and maximum deal size for each combination.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/data/groupbyWhen to prefer
Choose this endpoint when you need server-side grouping and multi-aggregate computation in a single call without setting up a database or running local data processing code. It is ideal for agents that receive tabular data and need summarized statistics quickly, especially when the data is already in JSON/array form and you want count, sum, avg, min, and max computed together. Prefer it over general-purpose code execution when you want predictable per-MB pricing and don't want to manage compute infrastructure.
Side effects
- Invalid or malformed input data returns a parsing error
- Referencing a column name that doesn't exist in the dataset causes a column-not-found error
- Unsupported aggregation function names return a validation error
- Extremely large payloads may timeout or exceed size limits
- Malformed JSON body returns a 400 bad request
- Missing required fields (data rows or grouping keys) returns a schema validation error
