How do I get an Anthropic API Key?

Log in to the [**Anthropic Console**](https://console.anthropic.com), go to **Account Settings > API Keys** and click **Create Key**. Copy the key immediately — it starts with `sk-ant-` and won't be shown again. You can also create workspace-scoped keys to control spending by use case.

What models are available?

Use the `list_models` tool to see all available Claude models. Current models include Claude Sonnet 4, Claude Opus 4 and Claude Haiku variants, each with different capabilities, context windows and pricing. The model ID format is like `claude-sonnet-4-20250514`.

Can I send multi-turn conversations?

Yes! Pass a messages array with alternating 'user' and 'assistant' roles. Each message has a 'role' and 'content' field. Claude will continue the conversation based on the full message history. Example: [{"role":"user","content":"Hello"},{"role":"assistant","content":"Hi!"},{"role":"user","content":"What's 2+2?"}].

How does batch processing work?

Use `create_batch_message` with an array of independent message requests. Each request is processed asynchronously and costs 50% less than individual requests. Use `get_batch_message` to check progress and results. Batches are ideal when you have many unrelated prompts to process.

Anthropic Alternative MCP Tools for Vercel AI SDK (6)

These 6 tools become available when you connect Anthropic Alternative to Vercel AI SDK via MCP:

cancel_batch_message

Requests that have already been completed cannot be cancelled. Provide the batch ID. This is useful if you submitted a large batch by mistake and want to stop further processing to save costs. Cancel an in-progress batch message request

count_tokens

Requires the model ID and messages array. Returns the total input token count. Useful for estimating API costs and ensuring messages fit within context limits. Count tokens in a message before sending to Claude

create_batch_message

Each request in the batch has its own model, messages, max_tokens, etc. This is more cost-effective than individual requests when you have many independent prompts to process. Returns a batch ID for tracking. Use get_batch_message to check progress. Create a batch of message requests to Claude

get_batch_message

Returns the batch status (in_progress, succeeded, expired, canceling, canceled, failed), request counts (total, succeeded, errored) and individual results. Use the batch ID returned from create_batch_message. Get the status of a batch message request

list_models

Each model returns its ID (e.g. "claude-sonnet-4-20250514"), display name, creation date and capabilities. Use this to discover which models are available and their IDs for use with the send_message tool. List all available Anthropic Claude models

send_message

Requires the model ID (e.g. "claude-sonnet-4-20250514") and messages array in JSON format. Each message must have a "role" ("user" or "assistant") and "content" (text or array of content blocks). Optionally set max_tokens (default 1024), system prompt and temperature (0-1). Returns the assistant's response text. Send a message to Claude (Messages API)

Example Prompts for Anthropic Alternative in Vercel AI SDK

Ready-to-use prompts you can give your Vercel AI SDK agent to start working with Anthropic Alternative immediately.

"Send a message to Claude asking 'What is the capital of Brazil?'"

"List all available Claude models."

"Count tokens for a message asking Claude to summarize a 500-word article."
