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 with a 'frequencies' array, where each element contains a 'value' (the unique item from the input array) and a 'count' (how many times it appeared). Results appear to be sorted by count in descending order, so the most frequent items come first.
Example use cases
Survey response tallying
“I have a list of survey answers like ["yes", "no", "yes", "maybe", "yes", "no"] — can you count how many times each response appears so I can see the breakdown?”
Log error frequency analysis
“Here are the error codes from my server logs: ["404", "500", "404", "403", "500", "404", "200"] — can you tally up how often each one occurs so I know which errors are most common?”
Word repetition counting
“I want to know which words repeat most in this list: ["the", "cat", "sat", "the", "cat", "on", "the", "mat"] — count the frequency of each word for me.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/json/array-frequency?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001 USDC) frequency count over a JSON array of up to 1000 items and want results without setting up local computation. Ideal for agents that need on-the-fly tallying of categorical data, survey responses, log codes, or any discrete value set without maintaining local state.
Side effects
- Array exceeds 1000 items — request rejected due to maxItems constraint
- Malformed JSON input — array not parseable returns error
- Empty array — returns empty frequencies list
- Payment failure — x402 payment of 0.001 USDC not processed, request blocked
- Network timeout on Cloudflare Workers edge
