Welcome to Lucid

Lucid is a verifiable AI inference protocol. Every AI call gets a cryptographic receipt, anchored on Solana, with full auditability.

Passports

Identity layer for models, compute nodes, tools, datasets, and agents

Inference

OpenAI-compatible chat completions with policy-based routing

Receipts

Cryptographic receipts with Merkle Mountain Range proofs

Epochs

Batch anchoring to Solana with verifiable transaction proofs

Agents

Autonomous agent orchestration with plan → accomplish → execute

Payouts

Automatic payout calculation and verification

​
Get Started in 2 Minutes

1

Install the SDK

npm install raijin-labs-lucid-ai
2

Run your first inference

import { LucidAI } from "raijin-labs-lucid-ai";

const lucid = new LucidAI({ bearerAuth: "your-api-key" });

const result = await lucid.chat.completions({
  model: "gpt-4o",
  messages: [{ role: "user", content: "Hello from Lucid!" }]
});
3

Verify your receipt

Every inference generates a cryptographic receipt anchored on Solana. Learn more →
65+ API endpoints are auto-documented in the API Reference tab with interactive playground.
