A Passport is the universal identity primitive in Lucid. Everything in the network — models, compute nodes, tools, datasets, and agents — has a passport.

​
Create a Passport

const passport = await lucid.passports.create({
  name: "my-gpt4o",
  type: "model",
  metadata: {
    provider: "openai",
    maxTokens: 128000,
    capabilities: ["chat", "function-calling", "vision"]
  },
  tags: ["production", "gpt-4o"]
});

​
List & Filter

// List all model passports
const models = await lucid.passports.list({
  type: "model",
  tags: ["production"]
});

// Get passport stats
const stats = await lucid.passports.stats();

​
On-Chain Sync

Passports can be synced to Solana for on-chain verification: 
await lucid.passports.sync(passportId);
Passport sync is batched — use GET /v1/passports/pending-sync to check the queue.
