How to Connect Flowise to APIVAI (Cheap Claude & GPT for Visual LLM Flows)

Connect Flowise to APIVAI

Flowise is a popular drag-and-drop builder for LLM apps and agents. Its
ChatOpenAI node accepts a custom base path, so you can route flows through APIVAI's Claude and GPT
models at a fraction of list price.

Configure the ChatOpenAI node

1. Add a ChatOpenAI node to your canvas.
2. In its credentials, set the OpenAI API Key to your APIVAI key.
3. In the node's Base Path / BasePath field, set: https://api.apivai.com/v1
4. Model Name: a name APIVAI serves (e.g. gpt-5.5, claude-sonnet-4-6).
5. Connect it into your chain/agent and run.

Confirm models

curl -s https://api.apivai.com/v1/models -H "Authorization: Bearer $APIVAI_API_KEY"

Build

Use the APIVAI-backed ChatOpenAI node in conversational chains, RAG flows, tool-using agents, or
multi-step workflows — same Flowise UX, cheaper model calls.

Troubleshooting

• 401 / connection error — check the Base Path (/v1) and the API key credential.
• model_not_found — use an exact name from /v1/models.

FAQ

Does Flowise work with APIVAI? Yes — set the ChatOpenAI node's Base Path to
https://api.apivai.com/v1, use your APIVAI key, and pick a model.

Which model? GPT-5.5 for fast/cheap; Claude Sonnet for code and long context.

Do I need code? No — it's node configuration in the Flowise canvas.

Get started

Set the Base Path + key on a ChatOpenAI node and build your flow on a model from /v1/models.
