POST /api/moving-average

live

Compute simple (SMA) and exponential (EMA) moving averages over a numeric series. Returns one value per input position - the first (window-1) SMA values are null since there isn't enough history. EMA uses the standard alpha = 2/(window+1) smoothing factor used in technical analysis.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://agent402.tools/api/moving-average' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
