## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nodeflare-avalanche-c-chain-rpc-chain-43114-23f291ef -d '<json body>'
```

Example prompt: Use Avalanche C-Chain RPC to call eth_getLogs on contract 0x60aE616a2155Ee3d9A68541Ba4544862310933d4 for Transfer events in the last 1000 blocks and return the raw results.

## When to prefer this

Choose this endpoint when you need full EVM JSON-RPC access to Avalanche C-Chain (chain 43114) including archive, trace, and debug methods, without setting up an account or API key. Ideal for AI agents that need pay-per-call access via x402/USDC for indexing, event log queries, contract simulation, or transaction debugging on Avalanche mainnet.

## Known failure modes

- Method not supported returns JSON-RPC error -32601
- Invalid params returns error -32602
- Insufficient USDC payment returns HTTP 402
- Node connectivity issues may return HTTP 503
- Revert in eth_call returns execution reverted error
- Requesting a pruned block on non-archive node returns missing trie node error

## How this service works

Avalanche C-Chain RPC (chain 43114): 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 JSON-RPC 2.0 response object containing the result of the requested method — e.g. a hex balance, array of log objects, call return data, transaction receipt, trace array, or debug trace depending on the method called. Errors return a JSON-RPC error object with code and message.
