Solana Agent Registration Health Check API Solana Agent Registration Health Check — verifies three.ws's server-custodial Solana agent-registration subsystem end-to-end by resolving a known canary agent's on-chain Metaplex Agent Registry record (Identity PDA + Core asset) and confirming both accounts exist on-chain right now. Returns a health snapshot with latency and the checked asset. Pay-per-call in USDC on Solana or Base mainnet.	-	$1,000.00	-	listed	call recipe →
three.ws Permit2 Demo Permit2 + EIP-2612 Gas Sponsoring Demo — forces the gasless Permit2 path so a fresh wallet holding USDC but ZERO ETH can complete the flow. The CDP facilitator submits the EIP-2612 permit and the Permit2 transfer atomically in a single transaction via x402ExactPermit2Proxy.settleWithPermit. The response carries the on-chain tx hash + Basescan link so callers can confirm the permit + transfer landed together. Pay $0.001 USDC on Base mainnet.	-	$0.001	-	listed	call recipe →
