Integrate NezhaGate through its OpenAI-compatible API.
Base URL: https://nezhagate.com/v1
API Key: read it from the environment variable NEZHAAPI_KEY.
Claude models can also use the native Anthropic protocol (for Claude Code / the Anthropic SDK): ANTHROPIC_BASE_URL=https://nezhagate.com/anthropic, headers x-api-key=API Key and anthropic-version: 2023-06-01, POST /anthropic/v1/messages (max_tokens is required), models claude-sonnet-4-6 / claude-opus-5 / claude-fable-5.
Chat models (/chat/completions): gpt-5.6-sol / gpt-5.6-terra / gpt-5.6-luna / gpt-5.5 / gpt-6-astra / claude-sonnet-4-6 / claude-opus-5 / claude-fable-5 / gemini-3.1-pro / gemini-3.8-flash / gemini-3.7-flash / gemini-3.6-flash / gemini-3.6-flash-high / gemini-3.6-flash-low / gemini-3.6-flash-tiered / gemini-3-flash-preview / gemini-3.5-flash / gemini-2.5-flash
Image models (text-to-image /images/generations; image-to-image /images/edits or add an image parameter): gpt-image-2 / gpt-image-2.5-flare / gpt-image-2.5-sunburst / nano-banana-2 / nano-banana-pro
Video models (text-to-video /videos/generations, async jobs; add an image parameter for image-to-video, the image becomes the first frame): veo-3.1 / seedance-2.5 / seedance-2.0 / seedance-2.0-fast / seedance-2.0-mini / wan3.0-video / wan3.0-video-prime / minimax-h3 / grok-imagine-video-1.5
Auth: Authorization: Bearer YOUR_API_KEY
Requirements (chat): return choices[0].message.content; on 401 check the key, 402 means insufficient balance, 429/5xx can be retried.
Requirements (images, async): POST /images/generations or /images/edits returns HTTP 202 with a job id right away ({"id":"img_...","object":"image.generation.job","status":"queued"}); then poll GET /v1/images/jobs/{id} until status=succeeded and read data[0].url (a stable link on img.nezhagate.com). Do not read data right after submitting.
Requirements (video, async): POST /videos/generations returns HTTP 202 with a job id (object=video.generation.job); then poll GET /v1/videos/jobs/{id} until status=succeeded and read data[0].url (a stable re-hosted mp4 link). About 1-2 minutes per clip; failed jobs are refunded in full.
