Rate limits
Understand the rate limits applied to Lightfield API requests.
The Lightfield API enforces rate limits. During this early launch period, the following limits apply per organization:
| Category | Method(s) | Limit |
|---|---|---|
| Write | Create, Update | 25 requests per second |
| Read | Retrieve, Definitions | 25 requests per second |
| Search | List | 25 requests per second |
Rate limit headers
Section titled “Rate limit headers”Every API response includes these headers:
| Header | Description |
|---|---|
X-RateLimit-Limit | Maximum requests allowed per second (bucket capacity) |
X-RateLimit-Remaining | Number of requests remaining in the current window |
X-RateLimit-Reset | Unix timestamp (seconds) when the bucket will be fully replenished |
Handling rate limit errors
Section titled “Handling rate limit errors”When you exceed the rate limit, the API responds with HTTP status 429 Too Many Requests. The response includes a Retry-After header indicating how many seconds to wait before retrying.
HTTP/1.1 429 Too Many RequestsRetry-After: 1X-RateLimit-Limit: 5X-RateLimit-Remaining: 0X-RateLimit-Reset: 1741392001
{ "type": "too_many_requests", "message": "Rate limit exceeded. Please try again later."}Best practices
Section titled “Best practices”- Implement exponential backoff — When you receive a 429, wait for the duration specified in
Retry-After, then retry with increasing delays on consecutive failures. - Monitor rate limit headers — Check
X-RateLimit-Remainingproactively to throttle your requests before hitting the limit. - Cache reads — Avoid redundant GET requests by caching responses on your end when the data doesn’t change frequently.
