Think of it as a single connection point in front of multiple model providers: not a new model, but a reliable, metered, and governable way for your agent or application to choose the right model for each task.

​
What problem does A2Agent solve？

  • Fragmented integration - every provider differs in auth, model IDs, API shape, context limits, and error codes.
  • Unstable availability - one account, route, or provider failure can stop the whole agent chain.
  • Unobservable costs - hard to trace token and model usage back to real business cost at multi-agent call volume.
  • Missing governance - quotas, concurrency limits, budget alerts, key rotation, and audit logs are hard to own in home-built solutions.

Key Features

All Major Frontier Models

Access GLM, Kimi, DeepSeek, Qwen, and MiniMax through one unified endpoint. Switch between models with a single parameter change — no extra accounts or keys required.

OpenAI & Anthropic Compatible

The API speaks the OpenAI Chat Completions protocol and supports the Anthropic message format. Any client that accepts a custom base URL works out of the box.

Pay As You Go

No monthly subscription or seat fees. Your balance never expires, so you only pay for what you use. Top up anytime via the Billing page.

Private & Secure

A2Agent does not persist your request payloads. Your prompts and completions pass through and are never stored on our infrastructure.

​
How It Works

  1. Connect - Replace base_url and api_key in your existing OpenAI or Anthropic client with A2Agent’s unified endpoint.
  2. Route - A2Agent authenticates the key, maps the requested model to an available upstream account, and applies health checks, retries, and failover before streaming the response.
  3. Meter & govern - Input and output tokens are metered into your prepaid balance, with model-level usage and billing visible in the console. Quotas, budget alerts, and audit logs apply per team.
New accounts include free trial credits so you can test models and latency before adding funds.

​
What A2Agent is not

A2Agent is not a foundation model or an agent builder. It does not train models, implement an agent’s internal reasoning, or replace a workflow engine. It is also not the A2A protocol or specification.

Quickstart
