FAQ

How does authentication work for this A2A authenticated LLM service?

Authentication is handled via Bcrypt for initial credential verification, followed by JWT (JSON Web Token) issuance for subsequent API calls. Unauthenticated requests are automatically rejected.

What LLM is used and how is it accessed?

The service utilizes the Gemini LLM via LangChain on Vertex AI. After successful authentication, your requests are routed through this LangChain-on-Vertex pipeline for completion.

How is pricing handled, and what are x402 micropayments?

The service is metered via x402 micropayments for usage. Discovery of the service is free, and costs are incurred based on actual LLM completions. x402 is a standard for machine-to-machine micropayments.

How do I connect to this A2A authenticated LLM service?

You connect to the service via standard A2A and MCP protocols. After obtaining your credentials and authenticating with Bcrypt to receive a JWT, you include this JWT in the headers of your subsequent requests to the LLM gateway.
