# NodeFlare Ink RPC (Chain 57073)

> NodeFlare Ink RPC (Chain 57073) is a paid API for AI agents from rpc.nodeflare.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Provides full JSON-RPC access to the Ink EVM chain (chain ID 57073) including archive, trace, and debug methods, billed per request in USDC via x402.

## Facts

- Endpoint: POST https://rpc.nodeflare.app/ink/x402
- Price: $0.001/call
- Payment: x402

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 nodeflare-ink-rpc-chain-57073-18ba841f -d '<json body>'
```

Example prompt: Call eth_getLogs on the Ink blockchain (chain 57073) to fetch all Transfer events from contract 0xAbC...123 between blocks 1000000 and 1001000 — pay per request via x402, no API key needed.

## When to prefer this

Choose this endpoint when you need full JSON-RPC access to the Ink EVM chain (57073) — especially archive queries, eth_getLogs, trace_, or debug_ methods — without registering an account or obtaining an API key, paying only for what you use via x402 USDC micropayments.

## Known failure modes

- Insufficient USDC balance or failed x402 payment returns payment-required error
- Invalid JSON-RPC method name returns method-not-found error
- Malformed params array returns invalid-params error
- Requesting a pruned block on a non-archive range returns missing trie node error
- Rate or compute-unit limits exceeded returns resource-exhausted error

## How this service works

Ink RPC (chain 57073): 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 JSON-RPC 2.0 response object containing the result field with chain data (block info, logs, call return values, traces, debug output) or an error field with code and message on failure.
