# NodeFlare Zircuit RPC (Chain 48900)

> NodeFlare Zircuit RPC (Chain 48900) 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 Zircuit blockchain (chain ID 48900) via NodeFlare's bare-metal nodes, supporting all standard and advanced methods including archive/trace/debug, paid per-request in USDC via x402.

## Facts

- Endpoint: POST https://rpc.nodeflare.app/zircuit/x402
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nodeflare-zircuit-rpc-chain-48900-ed47a927
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_xKcZBKXXQcfrXz4u1c_et

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-zircuit-rpc-chain-48900-ed47a927 -d '<json body>'
```

Example prompt: Can you call eth_getLogs on the Zircuit network (chain 48900) to fetch all Transfer events from contract 0xAbC...123 between blocks 1000000 and 1001000?

## When to prefer this

Choose this endpoint when you need RPC access specifically to the Zircuit blockchain (chain 48900) and want to pay per-request in USDC without needing an account or API key — ideal for AI agents using x402 micropayments. Prefer this over general-purpose RPC providers when you need archive/trace/debug methods for deep indexing, event queries, or transaction simulation on Zircuit specifically.

## Known failure modes

- Invalid JSON-RPC method returns error code -32601 Method not found
- Malformed request body returns -32600 Invalid Request
- Insufficient USDC balance or x402 payment failure results in HTTP 402
- Rate limits or node unavailability return HTTP 503
- Requesting non-archive data on archive-only methods without archive node support
- Block range too large for eth_getLogs returns execution timeout or result too large error

## How this service works

Zircuit RPC (chain 48900): 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 containing the result of the requested method call — e.g. block data, call return values, log arrays, gas estimates, or detailed trace/debug output depending on the method invoked. Errors are returned as JSON-RPC error objects with code and message fields.
