How this service works
Cronos RPC (chain 25): 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
Standard Ethereum JSON-RPC response object for the requested method: could include block objects, transaction receipts, contract return values, event log arrays, trace/debug output, or gas estimates — depending on the method called. Responses follow the standard eth_* JSON-RPC envelope with id, jsonrpc, and result fields.
Example use cases
DeFi event indexing on Cronos
“Pull all Swap events from the VVS Finance router contract on Cronos between blocks 12000000 and 12005000 — I need the full log data including topics and transaction hashes.”
Smart contract state simulation
“Run an eth_call on the Cronos chain to simulate calling the balanceOf function on the CRO token contract for my wallet address, without actually sending a transaction.”
Transaction trace for debugging
“I need a full debug_traceTransaction for tx hash 0xabc123... on Cronos mainnet — show me the internal calls and exactly where execution reverted.”
Technical details
Endpoint
POSThttps://rpc.nodeflare.app/cronos/x402When to prefer
Choose this endpoint when you need direct JSON-RPC access to the Cronos blockchain (chain ID 25) without setting up an account or API key, and you want pay-per-request USDC billing suitable for AI agent workflows. Especially valuable for archive/debug/trace methods not always available on free RPC tiers. Prefer over managed RPC services when you need no-signup access or are operating in an agentic payment context via x402.
Side effects
- Invalid JSON-RPC method returns error code -32601
- Malformed params return -32602 invalid params error
- Block not found for out-of-range block numbers
- Insufficient USDC payment results in 402 payment required
- Rate limiting or node unavailability returns 503
- eth_getLogs with too broad a filter may time out or return too many results
