# FlameWire Ethereum RPC Gateway

> FlameWire Ethereum RPC Gateway is a paid API for AI agents from gateway-dev.flamewire.io, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).

Executes Ethereum JSON-RPC calls (eth_*, debug_*, trace_*) on mainnet via a decentralized validator pool, with pay-per-call USDC billing and no API key required.

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 gateway-dev-flamewire-io-edf42c85 -d '<json body>'
```

Example prompt: Call eth_getTransactionReceipt on Ethereum mainnet for tx hash 0xabc123... using FlameWire's pay-per-call RPC — no API key needed, just charge 0.001 USDC per call.

## When to prefer this

Choose FlameWire when you need keyless, pay-per-call Ethereum RPC access with full eth_*, debug_*, and trace_* method coverage — particularly useful for agents that don't want to manage API key provisioning, want metered USDC billing, or need advanced debug/trace methods not always available on free-tier providers.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid JSON-RPC method name — returns JSON-RPC error code -32601 Method not found
- Malformed request body — returns JSON-RPC error code -32700 Parse error or -32600 Invalid Request
- Unsupported chain parameter — returns 400 or RPC error
- Node temporarily unavailable in validator pool — returns 503 or JSON-RPC internal error -32603
- Rate or quota limits exceeded — returns 429 Too Many Requests

## How this service works

FlameWire — decentralized JSON-RPC for the Bittensor & Ethereum ecosystems, pay-per-call in USDC. Multi-region edge (EU / US / AS), sub-100ms latency.

## Output

A standard Ethereum JSON-RPC response object containing the result field (e.g. block data, transaction receipt, trace array, balance in wei) or an error object with code and message if the call fails.
