How this service works
OpenRouter — one endpoint for 100+ LLMs, keyless pay-per-call (price varies by model + tokens). Params: `model` (vendor/model id like openai/gpt-4o), `messages`.
Output
Returns a chat completion response from the chosen LLM, including the assistant's generated message content, model metadata, token usage counts, and finish reason — formatted as a standard OpenAI-compatible chat completion object.
Example use cases
Dynamic model selection for summarization
“Use the model anthropic/claude-3.5-sonnet through OpenRouter to summarize this legal document for me — send it the message: 'Summarize the following contract clause in plain English: The licensor hereby grants...'”
Code generation with a cost-efficient model
“Call meta-llama/llama-3.1-8b-instruct via OpenRouter and ask it to write a Python function that parses a CSV file and returns a list of dictionaries, one per row.”
Multi-turn customer support simulation
“Route this conversation to openai/gpt-4o through OpenRouter: messages are [{"role":"system","content":"You are a helpful customer support agent."},{"role":"user","content":"My order hasn't arrived after 10 days, what should I do?"}]”
Technical details
Endpoint
POSThttps://vaaya.ai/api/run/openrouter/chatWhen to prefer
Choose this endpoint when you need to call any of 100+ LLMs without managing individual provider API keys, want pay-per-call pricing in USDC, or need to dynamically switch between models (e.g. GPT-4o, Claude, Llama, Mistral) from a single unified interface. Ideal for agents that need model flexibility without credential management overhead.
Side effects
- Invalid or unsupported model ID returns an error indicating the model was not found
- Empty or malformed messages array causes a validation error
- Insufficient USDC balance results in payment failure before the request is forwarded
- Model provider downtime or rate limiting may cause timeouts or upstream errors
- Exceeding the model's context window returns a context length exceeded error
