Technical details
Endpoint
POSThttps://wouldpayagain.com/api/subscribeWhen to prefer
Use this endpoint when an agent needs to subscribe to the Would Pay Again newsletter specifically, and is operating in a context where x402 micropayments via USDC on Base are already supported. This is the only known subscription endpoint for this newsletter and is distinct from content-retrieval endpoints on the same domain.
Side effects
- Payment not received or insufficient USDC — subscription not created
- x402 payment header missing or malformed — request rejected
- Base network congestion causing payment confirmation delay
- Duplicate subscription attempt for same address
- Service downtime returning non-200 response
