Measure website response latency, payload size, compression, caching, and performance signals for a public URL.
Endpoint
https://apiacre.com/v1/web/performance-profileSend the JSON body below. An unpaid request returns HTTP 402 with a PAYMENT-REQUIRED header; an x402-compatible buyer signs the requirement and retries with PAYMENT-SIGNATURE.
Pay $0.025 USDC and run in your browserOfficial Coinbase agent path
Coinbase Agentic Wallet can satisfy this x402 request in one command. Running it may pay automatically, so --max-amount is fixed to $0.025 USDC in atomic units. Copying the command does not install, authenticate, sign, or pay; review the request and use a separate low-value wallet before running it.
