Utvecklardokumentation

Standard (Async)

POST /api/v1/claude-opus-5-5 — returns request_id, poll for result via /api/v1/predictions/{id}/result.

Streaming (SSE)

POST /api/v1/claude-opus-5-5/stream — returns a live SSE stream. Each chunk: data: {"choices":[{"delta":{"content":"text"}}]}, ending with data: [DONE].

Vanliga frågor

Vanliga frågor

How is pricing calculated?

Pricing is token-based: $4.00 per million input tokens and $20.00 per million output tokens. The minimum charge per call is $0.0006. Actual cost is deducted after each call based on token counts returned by the model.

When should I use Opus 5.5 vs Opus 5 or Sonnet?

Use Opus 5.5 for the most complex tasks requiring deep reasoning, large codebases, or maximum reliability, at a lower cost than Opus 5. Use Sonnet for faster responses and everyday tasks — it offers a better cost/performance trade-off for most use cases.

Does Claude Opus 5.5 support images?

Yes. Pass an image_url in the request body to include an image as part of the user message.
