From 523f674fff9fd921b9ccc9efae50e3e115d777fe Mon Sep 17 00:00:00 2001 From: oyi77 Date: Sat, 16 May 2026 08:20:59 +0700 Subject: [PATCH] feat(deepseek-web): full DeepSeek web API executor with PoW solver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a complete executor for DeepSeek's native web API with: - Authentication via ds_session_id cookie → Bearer token from /users/current - Proof-of-Work (DeepSeekHashV1) solver using custom Keccak sponge - SSE stream response parsing with OpenAI-compatible output - Web search toggle (search_enabled) - Deep thinking toggle (thinking_enabled + x-thinking-enabled header) - File attachment support (ref_file_ids) - Auto-refresh executor for session management - 23 unit tests covering all features + live integration test API flow: /users/current → /chat_session/create → /create_pow_challenge → PoW solve → /chat/completion with native DeepSeek body format Co-Authored-By: OpenClaude (mimo-v2.5-pro) --- .../deepseek-web-with-auto-refresh.ts | 136 +++ open-sse/executors/deepseek-web.ts | 526 +++++++++++ open-sse/executors/index.ts | 6 + open-sse/lib/deepseek-pow-solver.cjs | 3 + open-sse/lib/deepseek-pow.ts | 60 ++ src/lib/providers/wrappers/deepseekWeb.ts | 93 ++ src/shared/constants/providers.ts | 10 + tests/live/deepseek-web-live.test.ts | 73 ++ tests/unit/deepseek-web.test.ts | 824 ++++++++++++++++++ 9 files changed, 1731 insertions(+) create mode 100644 open-sse/executors/deepseek-web-with-auto-refresh.ts create mode 100644 open-sse/executors/deepseek-web.ts create mode 100644 open-sse/lib/deepseek-pow-solver.cjs create mode 100644 open-sse/lib/deepseek-pow.ts create mode 100644 src/lib/providers/wrappers/deepseekWeb.ts create mode 100644 tests/live/deepseek-web-live.test.ts create mode 100644 tests/unit/deepseek-web.test.ts diff --git a/open-sse/executors/deepseek-web-with-auto-refresh.ts b/open-sse/executors/deepseek-web-with-auto-refresh.ts new file mode 100644 index 0000000000..ce890eb493 --- /dev/null +++ b/open-sse/executors/deepseek-web-with-auto-refresh.ts @@ -0,0 +1,136 @@ +import type { ExecuteInput } from "./base.ts";
