Lightchain AI RPC, on the same interface as every other chain.

Iteradian provides a managed Lightchain AI RPC endpoint. Requests are sent as JSON-RPC 2.0 with an API key and routed to a pool of managed Lightchain AI nodes, with an enforced rate limit, failover across the candidate list, and per-request usage analytics.

Why use a managed Lightchain AI endpoint?

Lightchain AI is an AI-integrated blockchain built around its AIVM execution environment. Iteradian exposes it through the same JSON-RPC 2.0 interface, the same API key and the same analytics pipeline as every other network, so you can add it to an existing integration without a second client library.

How do I connect to Lightchain AI?

  1. 01

    Create an API key

    Sign up for Iteradian and create a key in the dashboard. Production keys are prefixed itrd_live_ and test keys itrd_test_. The plaintext key is shown exactly once, so store it in a secret manager — never in source control.

  2. 02

    Send a JSON-RPC 2.0 request

    cURL
    curl -X POST https://api.iteradian.com/rpc/v1/lcai-mainnet \
      -H "Content-Type: application/json" \
      -H "X-Api-Key: itrd_live_YOUR_KEY" \
      -d '{"jsonrpc":"2.0","id":1,"method":"rpc_methods","params":[]}'
    TypeScript
    const res = await fetch("https://api.iteradian.com/rpc/v1/lcai-mainnet", {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "X-Api-Key": process.env.ITERADIAN_API_KEY!,
      },
      body: JSON.stringify({
        jsonrpc: "2.0",
        id: 1,
        method: "rpc_methods",
        params: [],
      }),
    });
    
    const { result } = await res.json();
    Python
    import os, requests
    
    res = requests.post(
        "https://api.iteradian.com/rpc/v1/lcai-mainnet",
        headers={"X-Api-Key": os.environ["ITERADIAN_API_KEY"]},
        json={"jsonrpc": "2.0", "id": 1, "method": "rpc_methods", "params": []},
    )
    
    print(res.json()["result"])

    Handle throttling

    Requests past your plan’s per-second rate or concurrency ceiling return HTTP 429 with JSON-RPC error code -32005 and a retryAfter value in error.data. Past the monthly allowance, requests run as metered overage until the plan’s overage cap, then return 429 with -32007. Throttled requests are recorded in your usage and request log too — nothing is dropped silently.

Lightchain AI RPC FAQ

01

How do I get a Lightchain AI RPC endpoint?

Create an Iteradian account, generate an API key, and send JSON-RPC 2.0 requests to https://api.iteradian.com/rpc/v1/lcai-mainnet with the key in an X-Api-Key header (Authorization: Bearer also works). New organizations start with a 7-day free trial.

02

What happens if I exceed the Lightchain AI rate limit?

The request receives HTTP 429 with a JSON-RPC error body. Code -32005 means your organization's per-second rate or concurrency limit — retry after `error.data.retryAfter` seconds. Code -32006 means the monthly quota is used up (`error.data.resetsAt` says when it resets) and -32007 means the overage spend cap is reached; retrying either cannot succeed until the period resets or the plan changes. Limits are shared by all of the organization's keys.

03

What happens if a Lightchain AI node goes down?

The gateway fails a request over to another healthy Lightchain AI node automatically, across up to 3 nodes. Transaction submissions are sent to one node and never retried or replayed by the gateway, so it cannot broadcast a transaction twice. If every node fails, the response is HTTP 503.

04

Which Lightchain AI RPC methods are supported?

Iteradian forwards JSON-RPC 2.0 requests to the Lightchain AI node, so the methods available are the methods that node exposes. Batch requests are supported (a batch of N calls counts as N requests). Subscriptions work over the WebSocket endpoint wss://rpc.iteradian.com/ws/v1/lcai-mainnet with the same API key.
