# NodeFlare Plasma RPC (Chain 9745)

> NodeFlare Plasma RPC (Chain 9745) is a paid API for AI agents from rpc.nodeflare.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Provides full JSON-RPC access to the Plasma EVM chain (chain ID 9745) including eth_getLogs, eth_call, trace, and debug archive methods, paid per-request in USDC via x402.

## Facts

- Endpoint: POST https://rpc.nodeflare.app/plasma/x402
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nodeflare-plasma-rpc-chain-9745-a2479680
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_tEcZ11_VJ6aQW-jUQYcNn

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-plasma-rpc-chain-9745-a2479680 -d '<json body>'
```

Example prompt: Can you call eth_getLogs on the Plasma chain (chain 9745) to fetch all Transfer events from contract 0xABC123... between blocks 1000000 and 1001000?

## When to prefer this

Choose this endpoint when you need direct, low-latency JSON-RPC access to the Plasma EVM chain (chain ID 9745) specifically, including archive and debug methods not available on free public nodes. Ideal for agents doing indexing, event queries, transaction simulation, or tracing on Plasma without managing API keys — pay-per-call in USDC via x402 makes it friction-free for autonomous agents.

## Known failure modes

- Invalid JSON-RPC method returns error object with code -32601
- Malformed params cause parse error -32700 or invalid params -32602
- Insufficient USDC payment via x402 results in 402 Payment Required
- Archive/debug methods may timeout or return errors on non-archive-accessible blocks
- Chain 9745 node unavailability returns 503 or connection error

## How this service works

Plasma RPC (chain 9745): 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

A standard JSON-RPC 2.0 response object with an id, jsonrpc version, and a result field containing chain data (logs, call return values, block info, traces, debug output, etc.) or an error object if the call failed.
