X402 List Api Plans Pricing

x402 List has no subscriptions, no accounts and no keys. Reads are free and anonymous up to a daily quota; past that the SAME endpoints answer HTTP 402 and settle per request over the x402 protocol on Base. Two paid write operations are priced per call rather than per plan, and one anti-spam fee applies to submissions from free compute hosts. There is no enterprise tier and no "contact sales" wall.
