Endpoint
https://x402.agentutility.ai/mp4-to-mp3-api
Verification
Checked 2 times without a pass yet. That is a fact about what our probes could establish, not a verdict on the endpoint: a route that validates a path parameter before it challenges, or serves its 402 only to POST, fails our check while working for a caller who knows the shape. The listing record shows what the probes found.
On-chain payments
Peak day 2026-09-11: 1,095 payments. Last indexed day 2026-10-09: 176. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 30 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
