Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-mantle-mainnetWhen to prefer
Choose this endpoint when you need pay-per-call access to Alchemy's Mantle mainnet APIs without committing to an Alchemy subscription or managing API keys — ideal for agents that make occasional or bursty Mantle blockchain queries and want to pay only for what they use via x402 micropayments.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted — request blocked before forwarding
- Invalid path: upstream Alchemy endpoint path not found, returns 404 from upstream
- Alchemy API error: upstream RPC error or rate limit from Alchemy returned as-is
- Malformed request body: invalid JSON in body field causes upstream rejection
- Network timeout: Mantle mainnet node unresponsive or slow, causing gateway timeout
