How this service works
Mantle RPC (chain 5000): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units. One of the first independent x402 RPC providers for this chain.
Output
A standard JSON-RPC 2.0 response object containing the result field (block data, call return value, log array, trace object, etc.) or an error field with code and message. Archive-depth data is available for historical queries; trace and debug methods return full execution traces.
Example use cases
Index DeFi events on Mantle
“Fetch all Transfer and Swap events from the Mantle chain for this DeFi contract address starting from block 5000000 to the latest block — I need to build an index of user activity.”
Simulate transaction before sending
“Before I send this transaction on Mantle, can you do an eth_call to simulate it and tell me if it will revert and what the return value would be?”
Debug failing smart contract call
“I'm getting a revert on Mantle chain — can you run a debug_traceCall on this transaction hash so I can see exactly where it's failing and why?”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/mantle/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Mantle-specific (chain 5000) RPC access including archive, trace, or debug methods without setting up an account or API key — ideal for AI agents using x402 micropayments. Prefer over generic RPC providers when you need pay-per-call pricing with no subscription, or when you need trace_transaction and debug methods that many hosted providers restrict.
Side effects
- Insufficient USDC payment — returns 402 Payment Required if x402 payment is missing or invalid
- Invalid JSON-RPC method name — returns JSON-RPC error code -32601 Method not found
- Malformed params — returns JSON-RPC error code -32602 Invalid params
- Node temporarily unavailable — returns 503 or timeout for transient infrastructure issues
- Block range too large for eth_getLogs — may return error asking to reduce range
