Endpoint
https://api.oblique.markets/api/v1/paid/wallet-spy
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
Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).
Peak day 2026-10-06: 89 payments. Last indexed day 2026-10-09: 5. 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 62 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.

Payment protocols
x402 · MPP: This endpoint's 402 also offers payment over MPP (the "Payment" HTTP authentication scheme): tempo, as the endpoint names them. Read from our unpaid probes; mpp_offers lists each offer. Our paid verification and on-chain figures cover x402 on Base only.
Paid verification
Not yet paid-verified. Probe-based status above is liveness only.
