How it works

Three steps. No humans involved.

01

Fund

Send USDC (SPL) on Solana mainnet to CQKviPv5QupKhE6MuhSuqP4uh1JfrL93nxtcx23tLMRk (min $0.01). Credits appear within seconds. Account is created automatically. Do not send SOL or other tokens.

02

Build

JSON-RPC, sendTransaction, WebSocket, Jito bundles, Yellowstone gRPC. Wallet-sig auth works immediately. Credits deducted per call by method weight.

03

API Key (optional)

Want lower-latency auth? Call /account/api-key with wallet sig to get an API key. Bots can skip this.

Infrastructure

The stack, top to bottom

No shared cloud pools. A single dedicated EPYC bare-metal box running Agave, one network hop from the Solana cluster.

Why Nodius

🔐

Wallet-Native Auth

Per-request Ed25519 signatures, session tokens, or API keys. Your bot picks the mode — no mandatory key management.

⚡

Smart Send

Routes through the fastest healthy send leg. Jito bundle support for MEV-protected landing.

📡

Yellowstone gRPC

High-throughput streaming — accounts, transactions, slots, blocks. Flat 60 cr/min, unlimited notifications.

🔌

WebSocket

accountSubscribe, logsSubscribe, slotSubscribe, and more. 5 cr to subscribe, 1 cr per notification.

📦

Bulk & Webhooks

Batch balance, token, and transaction lookups. Webhook callbacks for account activity.

🔥

Bare Metal

Dedicated EPYC server, local Agave, no shared pools. One hop from your request to the cluster.

Integration

Four lines to first call

SDK handles auth and billing. Or use raw HTTP with Ed25519 headers — works from any language.

TypeScript
import { NodiusClient } from "@nodius/sdk";

const rpc = NodiusClient.fromSecretKey(
  "https://rpc.nodius.xyz",
  "your-base58-secret-key"
);
// Send USDC to deposit — wallet-sig works immediately
const slot = await rpc.getSlot();
await rpc.call("sendTransaction", [tx]);

FAQ

Questions

How do I get started?
Send USDC (SPL) on Solana mainnet to the deposit address (CQKviPv5QupKhE6MuhSuqP4uh1JfrL93nxtcx23tLMRk, min $0.01). Credits appear within seconds. If you want an API key, call POST /account/api-key with a wallet signature. No signup form, no email, no KYC. Do not send SOL or other tokens.
How does x402 payment work?
When you make a request without sufficient credits, we return HTTP 402 with a PAYMENT-REQUIRED header containing Solana USDC payment instructions. x402-compatible client SDKs parse this, send a USDC payment, and retry automatically — your account is credited within seconds.
What authentication methods are supported?
Three: wallet signature (per-request Ed25519, no API key needed), API key (X-Api-Key header, generated via /account/api-key), and session tokens (challenge-response). Bots typically use wallet-sig or API key.
How are credits priced and do they expire?
Credits are purchased with USDC at the live rate (fetchable from /pricing). Credits expire after 10 days. Each RPC method has a credit cost based on its computational weight — cheap reads cost 1 credit, heavy queries cost up to 25.
Can I use this without downloading an SDK?
Yes. The API is standard JSON-RPC over HTTPS. Use curl, fetch, urllib, or any HTTP client. For wallet-sig auth, you need to sign the canonical message solana-nodius:v2:{METHOD}:{PATH}:{TIMESTAMP}:{NONCE}:{SHA256_BODY_HEX} with Ed25519. See the API reference for complete raw examples in Python, JavaScript, and curl.
Do you support WebSocket and gRPC streaming?
Yes. WebSocket at wss://rpc.nodius.xyz/ws (5 credits to subscribe, 1 per notification) and Yellowstone gRPC at grpc://rpc.nodius.xyz:10001 (60 credits/minute, unlimited notifications).
