The cheapest reliable paid API in the 5 categories agents pay for most, plus the week's biggest price moves and uptime drops, from 161,776 checks of 16,146 endpoints.
Top categories: the 5 with the most paying wallets in the last 30 days, fixed for the calendar month so weeks compare.
Cheapest reliable: each category's Hagglyai Pick when the Pulse was drafted: the cheapest endpoint per unit that scores 70+, was checked in the last 7 days, has repeat buyers and carries no warning.
Price moves: x402 endpoints whose price held steady in the week's last 3 days and 7–10 days before the week ended, and changed by 20% or more. A seller repricing several endpoints the same way counts once.
Uptime drops: x402 endpoints with 8+ checks in each of the last two weeks whose share of passing checks fell from 90% or more by 20 points or more. Recoveries are the reverse, ending at 95% or more.
Moves, drops and recoveries only include endpoints with 5+ paying wallets in 30 days. A check passes when the endpoint answers with a valid x402 payment request; Hagglyai never pays.
