Developer Portal

Unified API Key Access

One developer API key gives you access to our pricing and market data endpoints at https://dapp-mvp-boilerplate.onrender.com. Use it with the `x-api-key` header or `Authorization: ApiKey <key>`.

How it works

We issue a single API key to your project and manage access centrally. The backend stores only a salted SHA-256 hash of the key, so the raw key is never retained after issuance.

Developer keys are issued via admin-signed requests.
Raw keys appear once on creation.
Supported headers: x-api-key or Authorization: ApiKey <key>.
Existing routes remain unchanged unless explicitly protected.

Protected endpoints

These routes require your issued API key:

/api/binance
/api/coinbase
/api/coinranking
/api/1inch
/api/klines
/api/oracle
/api/pyth
/api/aggregator

Admin issuance

Key creation and revocation are protected by admin wallet signature proof. The admin must sign a message that matches the expected action:

ADMIN_API_KEY_MANAGEMENT

Send the signed payload to POST /api/api-keys. The response returns the raw key once in this format:

<key-id>.<secret>

Example requests

Using x-api-key header:

GET /api/binance/prices HTTP/1.1
Host: dapp-mvp-boilerplate.onrender.com
x-api-key: <your_api_key>

# Example with curl:
curl -H "x-api-key: YOUR_API_KEY" \
  https://dapp-mvp-boilerplate.onrender.com/api/binance/prices

Using Authorization header:

GET /api/coinbase/prices HTTP/1.1
Host: dapp-mvp-boilerplate.onrender.com
Authorization: ApiKey <your_api_key>

# Example with curl:
curl -H "Authorization: ApiKey YOUR_API_KEY" \
  https://dapp-mvp-boilerplate.onrender.com/api/coinbase/prices

Rate limiting

All API responses include rate limit headers to help you track your usage:

X-RateLimit-Limit: Maximum requests allowed per window
X-RateLimit-Remaining: Requests remaining in current window
X-RateLimit-Reset: Window duration in seconds

If you exceed your rate limit, you'll receive a 429 Too Many Requests response. Wait for the window to reset before making additional requests.

Error responses

The API uses standard HTTP status codes:

401 Unauthorized: Missing or invalid API key
403 Forbidden: Endpoint not authorized for your key
429 Too Many Requests: Rate limit exceeded
500 Internal Server Error: Server-side error

All error responses include a JSON body with details:

{
  "success": false,
  "error": "Rate limit exceeded"
}

Need help?

If you want, I can also add a small admin dashboard page for key issuance and revocation flows.
