x402
NodeFlare Polygon PoS RPC (Chain 137) is a paid API for AI agents from rpc.nodeflare.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).
Executes any Ethereum JSON-RPC method against Polygon PoS (chain 137) via NodeFlare's bare-metal archive nodes, billed per-request in USDC with no API key required.

How this service works
Polygon PoS RPC (chain 137): 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.
Output
A standard JSON-RPC 2.0 response object containing either a 'result' field with the method's return value (e.g. hex-encoded data, log arrays, block objects, trace frames) or an 'error' field with code and message if the call failed.
Example use cases
Index DeFi events on Polygon
“Fetch all Swap events emitted by the QuickSwap router on Polygon between blocks 55000000 and 55005000 — I need the raw log data including topics and transaction hashes.”
Simulate contract call before sending
“Run eth_call on Polygon mainnet to simulate calling the balanceOf function for wallet 0xAbCd...1234 on the USDT contract at 0xc2132D05D31c914a87C6611C10748AEb04B58e8F — I want to know the result before broadcasting anything.”
Debug a reverted Polygon transaction
“Use trace_transaction on Polygon to debug why the transaction 0xdeadbeef...cafe reverted — I need the full execution trace so I can see exactly where it failed.”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/polygon/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to query Polygon PoS (chain 137) specifically and want archive depth (eth_getLogs, trace, debug) without managing API keys or subscriptions. Ideal for AI agents that pay per-call via x402/USDC rather than maintaining a monthly plan. Prefer this over generic RPC providers when you need trace and debug methods, event indexing across large block ranges, or contract simulation on Polygon archive state.
Side effects
- Invalid JSON-RPC method name returns error code -32601 (method not found)
- Malformed params array returns error code -32602 (invalid params)
- Requesting a block range too large for eth_getLogs may return a range-limit error
- Insufficient USDC balance causes payment failure before the RPC call is executed
- Network congestion on Polygon can cause occasional timeouts on heavy archive queries
- Trace/debug methods on very old blocks may time out if compute units exceed limits
