We have just added Claude Opus 4.7 to the YepAPI chat catalog. It's Anthropic's newest and most capable Claude yet — pushing the frontier on complex reasoning, agentic tool use, and advanced coding — and it's callable from the same `/v1/ai/chat` endpoint you already use for every other LLM under your key, with pay-per-token pricing and no waitlist.
What's new
- Latest-generation Claude flagship (model ID: `anthropic/claude-opus-4.7`)
- Full 1,000,000 token context window
- Best-in-class reasoning, agentic workflows, and code generation
- Drop-in on the unified `/v1/ai/chat` endpoint — same envelope, same auth
- Short alias `claude-opus` now resolves to 4.7
Endpoints in this release
What Claude Opus 4.7 is good for
Opus 4.7 is the new top of the Claude lineup — strongest on multi-step reasoning, long-horizon agents, deep code review, and nuanced long-form writing. With a 1M token context window, you can drop entire codebases, research libraries, or long document sets into a single call.
How to call it
Pass `anthropic/claude-opus-4.7` as the `model` on the `/v1/ai/chat` endpoint. Streaming is supported via `stream: true`. Everything else — auth, billing, retries, rate limits — works exactly like every other model on YepAPI.
