Our planning agent runs 40-step workflows on the GLM 4.7 API without losing the thread — that long-horizon reliability is what we could not get before.
The GLM 4.7 API is Z.ai's latest flagship GLM model — tuned for long-horizon agents, strict instruction-following, and deep reasoning, with a 200K-token context window, native tool calling, and structured outputs. The GLM 4.7 API is OpenAI-compatible: point any existing SDK at RouterBase and set the model to glm-4-7. Input at $0.51 / 1M tokens, output at $1.87 / 1M tokens, cached-input reads at $0.0935 / 1M — 15% below the official rate, all through one REST endpoint.

GLM 4.7 API: Chat
Use the GLM 4.7 API to run Z.ai's latest flagship — the most dependable GLM yet for long, multi-step agent runs, strict instruction-following, and deep reasoning, all OpenAI-compatible.
The GLM 4.7 API is Z.ai's latest flagship — built for long, multi-step agent runs, strict instruction-following, and deep reasoning, with native tool calling, structured outputs, and a 200K-token context window. Routed through RouterBase, the GLM 4.7 API is fully OpenAI-compatible: point any existing SDK at RouterBase's base URL, set the model to glm-4-7, and your first GLM 4.7 API call goes through immediately.
Pricing for the GLM 4.7 API is $0.51 / 1M input tokens, $1.87 / 1M output tokens, and $0.0935 / 1M cached-input reads — 15% below the official published rate. One RouterBase key reaches the GLM 4.7 API and 200+ other models — no Z.ai account required.
Six reasons teams ship on the GLM 4.7 API
From rock-solid agent runs to a 15%-off price — six reasons teams standardize on GLM-4.7.
Built for long agent runs
The GLM 4.7 API holds a plan across dozens of tool calls without drifting — the long-horizon reliability that makes autonomous agents actually shippable.
Follows instructions exactly
Give the GLM 4.7 API a strict format, schema, or style guide and it sticks to it — fewer re-asks, cleaner structured outputs, and less post-processing on your side.
Native tool calling
The GLM 4.7 API calls functions in the OpenAI format and rarely malforms a call, even deep in a chain — so multi-tool agents stay on the rails.
Long context window
The GLM 4.7 API reads up to a 200K-token context — whole codebases, case files, or a full session of agent history fit in one request.
OpenAI-compatible, one key
The GLM 4.7 API speaks the OpenAI chat-completions format, so the same RouterBase key swaps it in for GPT-5.5, Claude, Gemini, or any of 200+ models.
15% off the list price
GLM-4.7 runs 15% under Z.ai's published rate — $0.51 / 1M input, $1.87 / 1M output, $0.0935 / 1M cached. Flagship reasoning without flagship pricing.
Quickstart
Get started with the GLM 4.7 API in 3 steps
From sign-up to your first response in under 5 minutes.
Create a RouterBase API key
Sign up and mint an API key — it reaches GLM-4.7 and every other model in the RouterBase catalog from one place.
Send your first message
Point any OpenAI-compatible SDK at routerbase.com/v1 and set the model to glm-4-7. Streaming, tool calls, and structured outputs all follow the standard chat-completions schema.
Inspect usage
Every GLM 4.7 API response returns a full token breakdown — input, output, and cached-input — so cost and cache hits stay visible on every call.
Pay only for what you use
RouterBase passes through partner-tier pricing. Compared against the model's official published API rate.
What teams build with the GLM 4.7 API
Real production loads running on the RouterBase model catalog across 200+ models.
We standardized on the GLM 4.7 API through RouterBase in one line — strict JSON every time let us delete a whole layer of output validation.
Across long tool chains the GLM 4.7 API barely malforms a call — our agents now finish multi-step tasks that used to stall halfway.
We A/B the GLM 4.7 API against GPT and Claude behind one RouterBase key — it matches them on our reasoning evals for a fraction of the cost.
Long agent scaffolding plus cached-input pricing keeps our bill flat — the GLM 4.7 API rereads the same context cheaply every turn.
Pointing our OpenAI SDK at the GLM 4.7 API took one base-URL change, and the structured outputs landed in the exact shape we asked for.
