Anthropic-compatible API

rout.my exposes an Anthropic Messages-compatible endpoint for clients that send Anthropic request shapes.

POST https://api.rout.my/v1/messages
POST https://api.rout.my/v1/messages/count_tokens
POST https://api.rout.my/anthropic/v1/messages
POST https://api.rout.my/anthropic/v1/messages/count_tokens

Client base URL

If a client asks for a base URL and appends /v1/messages itself, configure:

https://api.rout.my

Use the full endpoint URL only in manual curl requests. Do not set Anthropic SDK or Claude Code base URL to https://api.rout.my/v1, or the client may call /v1/v1/messages.

Authentication

Bearer auth works:

Authorization: Bearer sk_your_key_here

Anthropic-style headers are also accepted by the route:

x-api-key: sk_your_key_here
anthropic-version: 2023-06-01

Request

curl https://api.rout.my/v1/messages \
  -H "x-api-key: $ROUTMY_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-sonnet-4.6",
    "max_tokens": 256,
    "messages": [
      { "role": "user", "content": "Write one short sentence." }
    ]
  }'

Notes

Topic	Behavior
model	Use an exact model ID available to your account.
messages	Anthropic-style messages are converted internally.
Images	Image blocks are converted when the selected model supports vision input.
Streaming	Anthropic-style streaming is supported when requested by the client.
Token counting	POST /v1/messages/count_tokens returns { "input_tokens": n } using the same local estimator as request accounting.
Tool use	Client tools are translated where compatible; native Anthropic-only tool fields are preserved for native Anthropic providers.
Native params	container, service_tier, metadata, thinking, mcp_servers, context_management, output_config, cache_control, and inference_geo are accepted and preserved where supported.
Beta headers	anthropic-beta and anthropic-version headers are forwarded to native Anthropic providers.

Use this route when a client specifically expects Anthropic Messages. For OpenAI-compatible SDKs, prefer /v1/chat/completions.
