How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a single 'count' field containing the integer number of elements in the provided array, e.g. {"count": 3}.
Example use cases
Counting unique product SKUs
“I have a list of product IDs from this week's orders — can you count how many there are? Here's the array: ["SKU001", "SKU002", "SKU003", "SKU004", "SKU005"]”
Validating batch submission size
“Before I submit this batch job, can you tell me how many items are in my queue? The array has entries like ["job-1", "job-2", ..., "job-47"] — I need the exact count to check it's under 1000.”
Counting survey responses
“I collected responses from participants and stored them as an array. Can you count how many responses I got? Here's the list: ["yes", "no", "yes", "maybe", "yes", "no"]”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/array/count?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call array count operation without standing up your own compute infrastructure. Ideal for autonomous agents that occasionally need to count items without access to a runtime environment. At $0.0009 USDC per call via x402, it is cost-effective for infrequent or agent-driven counting tasks where local computation is unavailable.
Side effects
- Array exceeds 1000 items — request will be rejected or truncated
- Empty or missing 'values' field returns count of 0 or an error
- Non-array input for 'values' field may cause a validation error
- Payment failure via x402 protocol prevents the call from completing
- Network timeout on Cloudflare Workers edge
