API_Dalla — API Witchcraft
A hands-off, pay-per-call API marketplace. Every endpoint is payable via x402 (HTTP 402, USDC on Base) and/or RapidAPI (API key). No accounts, no contracts — agents pay per call.
Endpoint
https://apiwitchcraft.duckdns.org/crypto/price
Verification
Checked 9681 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 (11 most recent sampled): 11 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).
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. Methodology.
