)let anthropic = Anthropic(apiKey: "YOUR_OWN_API_KEY")
let message = Message(role: .user, content: [.text("This is test text")])
let response = try await anthropic.messages.createMessage([message], maxTokens: 1024)This library currently supports Messages API. If you need legacy Text Completion API, please make PRs or Issues.
Send a structured list of input messages with text and/or image content, and the model will generate the next message in the conversation.
The Messages API can be used for for either single queries or stateless multi-turn conversations.
let anthropic = Anthropic(apiKey: "YOUR_OWN_API_KEY")
let message = Message(role: .user, content: [.text("This is test text")])
let response = try await anthropic.messages.createMessage([message], maxTokens: 1024)
for content in response.content {
switch content {
case .text(let text):
print(text)
case .image(let imageContent):
// handle base64 encoded image content
}
}Send a structured list of input messages with text and/or image content, and the model will generate incrementally stream the response using server-sent events (SSE).
let anthropic = Anthropic(apiKey: "YOUR_OWN_API_KEY")
let message = Message(role: .user, content: [.text("This is test text")])
let stream = try await anthropic.messages.streamMessage([message], maxTokens: 1024)
for try await chunk in stream {
switch chunk.type {
case .messageStart:
// handle message start object with casting chunk into `StreamingMessageStartResponse`
}
}This library provides support for the Anthropic Bedrock API through a separate package.

)To create an AnthropicBedrockClient from a BedrockRuntimeClient with a Model to access Claude on Bedrock.
The API usage is the same as the normal AnthropicClient.
let client = try BedrockRuntimeClient(region: "USEast1")
let anthropic = BedrockRuntimeClient.useAnthropic(client, model: .claude_3_Haiku)
let response = try await anthropic.messages.createMessage(Message(role: .user, content: [.text("This is test text")]), maxTokens: 1024)
for content in response.content {
switch content {
case .text(let text):
print(text)
case .image(let imageContent):
// handle base64 encoded image content
}
}Of course, Streaming Message API works in the same way.
let client = try BedrockRuntimeClient(region: "USEast1")
let anthropic = BedrockRuntimeClient.useAnthropic(client, model: .claude_3_Haiku)
let stream = try await anthropic.messages.streamMessage([Message(role: .user, content: [.text("This is test text")])], maxTokens: 1024)
for try await chunk in stream {
switch chunk.type {
case .messageStart:
// handle message start object with casting chunk into `StreamingMessageStartResponse`
}
