# Goldsky Edge RPC — Avalanche C-Chain (EVM Chain 43114)

> Goldsky Edge RPC — Avalanche C-Chain (EVM Chain 43114) is a paid API for AI agents from edge.goldsky.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-31).

Executes standard EVM JSON-RPC calls against the Avalanche C-Chain (chainId 43114) via Goldsky's pay-per-call Edge RPC gateway

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 goldsky-edge-rpc-avalanche-c-chain-evm-chain-43114-f84c6906 -d '<json body>'
```

Example prompt: Check the AVAX balance of wallet 0xAbC...123 on Avalanche C-Chain right now using a standard eth_getBalance RPC call.

## When to prefer this

Choose this endpoint when your agent needs low-latency EVM JSON-RPC access to Avalanche C-Chain (chainId 43114) and wants pay-per-call micropayment billing via x402 rather than managing a monthly API key subscription. It supports the full eth_*, debug_*, trace_*, net_*, and web3_* method surface including batch requests, making it suitable for both simple balance lookups and advanced trace queries against Avalanche.

## Known failure modes

- Insufficient prepaid balance returns a 402 Payment Required response
- Invalid JSON-RPC method name returns error code -32601 Method not found
- Malformed params return error code -32602 Invalid params
- Network congestion or node unavailability may cause timeouts or 503 responses
- Sending to wrong chainId silently succeeds but data will be wrong — caller must ensure chainId 43114
- Batch requests with too many sub-calls may be rejected or rate-limited

## How this service works

Goldsky Edge RPC — prepaid balance, funds ~1000 requests at 5 atomic units each

## Output

A standard JSON-RPC 2.0 response object (or array for batch requests) containing the `result` field with the requested on-chain data, or an `error` object with code and message if the call fails. For reads this includes values like balances, block objects, receipts, and logs; for writes it returns a transaction hash.
