Trusset Protocol - Infrastructure for Asset Tokenization

The API enforces per-key and per-IP rate limits to ensure fair usage. Limits vary by API and endpoint sensitivity.

Instance API Limits

Instance API endpoints (Customers, Tokenization, Trading, etc.) apply layered rate limiting.

Limiter	Window	Limit	Scope
Global	1 minute	100 requests	Per IP
API Key	1 minute	200 requests	Per API key
Auth	15 minutes	15 requests	Per IP (auth endpoints only)
Key Management	1 minute	30 requests	Per user/issuer
Strict	1 minute	10 requests	Per IP (sensitive operations)

The global and API key limiters run on every request. The stricter limiters apply only to specific endpoint groups. When multiple limiters apply, the most restrictive active limit governs.

Response Headers

Header	Description
`X-RateLimit-Limit`	Maximum requests in the current window
`X-RateLimit-Remaining`	Remaining requests in the current window
`X-RateLimit-Reset`	Unix timestamp when the window resets
`Retry-After`	Seconds until the next request is allowed (only on `429` responses)

429 Response

{
  "success": false,
  "error": {
    "code": "RATE_LIMIT_EXCEEDED",
    "message": "Too many requests, please try again later"
  },
  "metadata": {
    "retryAfter": 42,
    "timestamp": "2025-06-15T12:00:00.000Z"
  }
}

MiCA Register API Limits

The MiCA Register API enforces separate per-key limits.

Window	Limit
Per minute	60 requests
Per day	5,000 requests (resets at midnight UTC)

MiCA rate limit headers use a different format:

Header	Description
`X-RateLimit-Limit-Minute`	Maximum requests per minute
`X-RateLimit-Remaining-Minute`	Remaining requests in the current minute
`X-RateLimit-Limit-Day`	Maximum requests per day
`X-RateLimit-Remaining-Day`	Remaining requests for the current day

Caching

Most read endpoints return Cache-Control headers. Respecting these headers reduces unnecessary requests against your quota.

Endpoint group	Cache TTL
MiCA list/detail	300s (5 min)
MiCA statistics, license types, countries	600s (10 min)
MiCA search	120s (2 min)

Use the X-RateLimit-Remaining (or X-RateLimit-Remaining-Minute) header to implement client-side throttling before hitting the limit.
