How this service works
Sum of a numeric list. Call when you aggregate agent-held amounts without a spreadsheet. Returns sum and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the arithmetic sum of all numeric values in the input array along with the count of elements processed. No data is retained after the call.
Example use cases
Totaling agent expense amounts
“I have a list of expenses my agent logged this week — [42.10, 18.75, 9.99, 130.00, 55.50] — can you sum them up and tell me the total and count?”
Aggregating inventory quantities
“Here are the stock counts across our warehouses: [200, 150, 320, 75, 410]. What's the total inventory and how many warehouse entries are there?”
Summing collected scores
“I've got a batch of scores from our user survey: [8, 7, 9, 6, 10, 7, 8]. Add them all up and tell me the total and count so I can calculate the average myself.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/sum-nWhen to prefer
Choose this endpoint when an AI agent needs to aggregate a list of numbers at runtime without access to a spreadsheet, database, or local computation environment. It is ideal for lightweight, stateless arithmetic over agent-held data where a full data pipeline is overkill and privacy matters since no data is retained.
Side effects
- Empty array input may return zero for sum and zero for count
- Non-numeric values in the array may cause a validation error or be skipped
- Malformed JSON body returns an error response
- Payment failure via x402 prevents the call from being processed
