Passports - Lucid

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

Passport Types

Type	Description	Example
`model`	LLM or AI model	GPT-4o, Claude 3.5 Sonnet
`compute`	Compute node provider	GPU worker, inference server
`tool`	External tool or API	Web search, calculator
`dataset`	Training or reference data	Knowledge base, embeddings
`agent`	Autonomous agent	Planning agent, research agent

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.
