AI Coding

AI Coding lets you connect popular AI coding tools — Claude Code, OpenAI SDK, IDE extensions — directly to models operated by GreenNode, using cloud models without managing API keys from external providers.

---

Architecture

Requests from your tool are redirected to a GreenNode endpoint. The endpoint exposes two protocols in parallel to support all existing clients:

Both API protocols connect to a single endpoint sharing the same Model Pool

A single key works for both protocols — but the key must match the host of the service type that issued it.

Two service types — settle this before configuring anything

Service type	Pricing model	Key used to call	Base URL host
PAYG	Pay per token actually used	API Key from API Keys	maas-llm-aiplatform-hcm.api.vngcloud.vn
Token Plan	Prepaid 30-day package with a fixed token quota	subscription-key from Plan Detail → Subscription keys tab	tokenplan.api.greennode.ai

---

Base URL by service type and client standard

Service type	Anthropic-standard clients (Claude Code, Anthropic SDK)	OpenAI-standard clients (OpenAI SDK, LiteLLM, Cursor, Continue.dev, Codex, OpenCode)
PAYG	https://maas-llm-aiplatform-hcm.api.vngcloud.vn	https://maas-llm-aiplatform-hcm.api.vngcloud.vn/v1
Token Plan	https://tokenplan.api.greennode.ai	https://tokenplan.api.greennode.ai/v1

Picking the wrong cell in this table is the most common failure: the wrong /v1 suffix gives 404 Not Found; the wrong host for your key type gives 401 Unauthorized even while the key is still valid. Every tool guide has separate tabs per service type — pick your tab and copy it as-is.

Supported Tools

Claude Code

Claude Code CLI supports overriding ANTHROPIC_BASE_URL — pointing to a GreenNode endpoint instead of Anthropic directly. All sessions, tool calls, and sub-agents route through the GreenNode endpoint, with usage visible in AI Platform Console.

OpenAI-compatible clients

Any tool that allows setting a custom base_url in OpenAI SDK format works out of the box — OpenAI Python/Node.js SDK, LiteLLM, Cursor, Continue.dev, and other IDE extensions. Change the base URL and key; no logic changes needed.

Billing

	PAYG	Token Plan
Pricing	Credit-token, 1 credit = 1 VND	Fixed prepaid 30-day package
Quota	Prepaid: credits deducted every 5-minute collection cycle; model auto-disabled when credits run out. Postpaid: usage recorded as debt with no quota limit	Fixed token/request quota per model, shared across all subscription-keys in the plan
Where to track	AI Platform Console → Usage and Cost	AI Platform Console → Usage only
