How to Call the Anthropic API

Submit a JSON request with your Muapi API key, save the request ID, and poll the shared result endpoint — or call the /stream variant for a live SSE token feed. The request shape is identical across every Claude model.

1. Prompt an Claude Fable 5.1 senden

curl -X POST https://api.muapi.ai/api/v1/claude-fable-5-1 \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"Research and compare three architectures for this system, citing tradeoffs.","system_prompt":"You are a precise principal engineer."}'

# Response: {"request_id":"REQUEST_ID"}

Call claude-fable-5-1 with a prompt, and optionally a system_prompt and image_url.

2. Ergebnis abrufen

curl https://api.muapi.ai/api/v1/predictions/REQUEST_ID/result \
  -H "x-api-key: YOUR_API_KEY"

# Poll until status is completed, then read the generated text from outputs.

Poll until the task is completed, then read the generated text from outputs.

3. Antwort stattdessen streamen

curl -X POST https://api.muapi.ai/api/v1/claude-fable-5-1/stream \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"Walk through a long-horizon plan for this migration, step by step."}'

# Response: a stream of SSE chunks, one per line:
# data: {"choices":[{"delta":{"content":"Here"}}]}
# data: {"choices":[{"delta":{"content":" is"}}]}
# data: [DONE]

Call claude-fable-5-1/stream with the same fields to receive SSE chunks as the model generates them, ending in a [DONE] marker.
