Everything you need to integrate cStudios — authentication, rate limits, error handling and the full endpoint reference.
Welcome to cStudios. Integrating takes three steps:
status, request_id, data and response_time_ms.Base URL: https://api.cstudio.sbs
All endpoints authenticate with an API key passed in the X-API-Key header. Keep keys server-side — never expose them in browsers or mobile apps.
curl -X GET "https://api.cstudio.sbs/v1/upi/verify?upi_id=name@okhdfcbank" \
-H "X-API-Key: YOUR_API_KEY"Each API has its own Test, Pro, Ultra and Mega plan with a monthly request quota — see Pricing for per-API quotas. Rate limits are applied per API key:
| Plan | Monthly Quota | Rate Limit |
|---|---|---|
| Starter | Per API plan | 1000 requests / hour |
| Pro | Per API plan | Uncapped |
| Ultra | Per API plan | Uncapped |
| Mega | Per API plan | Uncapped |
Response headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset
Errors use conventional HTTP status codes with a consistent JSON body:
{
"status": "error",
"request_id": "req_1a2b3c4d",
"error": {
"code": 401,
"message": "Invalid or missing API key"
}
}| Code | Meaning |
|---|---|
| 200 | Success — data returned in the data object. |
| 400 | Bad Request — missing or malformed parameter. |
| 401 | Unauthorized — invalid or missing API key. |
| 402 | Payment Required — quota exhausted, upgrade your plan. |
| 404 | Not Found — no record exists for the given input. |
| 429 | Rate Limited — slow down, see X-RateLimit-Reset header. |
| 500 | Server Error — retry with exponential backoff. |
| 503 | Upstream Unavailable — source temporarily down, retry shortly. |
