A JSON array of review objects, each containing: feed version, endpoint URL, origin, price paid in USDC, listed price in USDC, on-chain settlement transaction hash, settlement network, latency in milliseconds, 1-5 ratings for latency/output quality/docs quality/would-pay-again, delivery confirmation, sample count, a request example, a verdict string, and a tested_at timestamp.
Example use cases
Example prompt
“Pull the latest Would Pay Again review feed so I can see which x402 endpoints have been tested, what people actually paid in USDC, and whether reviewers would pay again — I want to check quality scores and Basescan-verifiable settlement transactions.”
Technical details
Endpoint
GEThttps://wouldpayagain.com/api/reviewsWhen to prefer
Use this endpoint when you need verified, on-chain-backed quality assessments of x402-paywalled APIs, especially when evaluating whether a micropayment API is worth integrating. Prefer this over general API directories when you specifically care about actual USDC costs, latency benchmarks, and community 'would pay again' scores tied to Basescan-checkable transactions.
Side effects
- Payment not received (402 response — must pay $0.01 USDC via x402 protocol to access)
- Feed temporarily unavailable (503)
- Stale data if newsletter review cycle hasn't published recently
- No query parameter support — filtering must be done client-side
