One API call. Four AI models. One synthesized answer.
Stop managing multiple AI provider APIs. Synero's REST API sends your query to four models simultaneously and returns each response plus a synthesized answer — all through a single endpoint with SSE streaming.
/api/querySend a prompt and receive streaming responses from four AI advisors plus a synthesized answer.
Capabilities
Four Models, One Call
Query GPT, Claude, Gemini, and Grok simultaneously. Choose from 15 models across four providers. Assign any model to any advisor slot.
SSE Streaming
Responses stream in real-time via Server-Sent Events. Watch four advisors reason in parallel, then see the synthesis emerge live.
Configurable Advisors
Four advisor roles (Architect, Philosopher, Explorer, Maverick) with editable system prompts. Customize reasoning styles per query or per session.
Simple Authentication
Bearer token auth with API keys you can generate and revoke from your dashboard. No OAuth flows, no complex setup.
Structured Responses
Each response includes the advisor name, model used, full reasoning, and the final synthesis. Parse structured JSON or consume the SSE stream directly.
OpenAPI Specification
Full OpenAPI 3.0 spec available for code generation, testing, and documentation. Import into Postman, Swagger, or your preferred toolchain.
Code Example
const response = await fetch('https://synero.ai/api/query', {
method: 'POST',
headers: {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json',
},
body: JSON.stringify({
prompt: 'Compare PostgreSQL and MongoDB for a real-time analytics product',
}),
});
// SSE stream: advisor responses + synthesis
const reader = response.body.getReader();
const decoder = new TextDecoder();
while (true) {
const { done, value } = await reader.read();
if (done) break;
const chunk = decoder.decode(value);
// Each chunk: { advisor, model, content, type }
console.log(chunk);
}Frequently asked questions
How many models can I query per request?
Each request queries up to four AI advisors simultaneously. You can configure which models power each advisor slot — choosing from 15 models across OpenAI, Anthropic, Google, and xAI.
What's the latency like?
With SSE streaming, the first tokens arrive within 1-2 seconds. All four advisors stream in parallel, so total response time is determined by the slowest model — typically 10-30 seconds for a full council response including synthesis.
How is pricing structured?
Synero charges per query using a credit system. Each API call costs credits based on the models used and token volume. Credits are included in the $10/month subscription with top-ups available.
Can I use this for production applications?
Yes. The API is designed for production use with rate limiting, error handling, and retry logic. See the developer documentation for best practices on building production integrations.
