Rate Limits

The API enforces rate limits per org to ensure fair usage and platform stability.

Limits

Window	Limit
Per second	50 requests
Per minute	1,000 requests

Applied per org (keyed off your API key) across all data API endpoints. The per-second cap absorbs bursts; the per-minute cap governs sustained throughput. Exceeding either returns 429 Too Many Requests.

Rate Limit Headers

Every response carries your current quota state — on success and on 429 — so you can self-pace before you ever get throttled:

Header	Description
`X-RateLimit-Limit-Second`	Per-second ceiling (`50`)
`X-RateLimit-Limit-Minute`	Per-minute ceiling (`1000`)
`X-RateLimit-Remaining`	Requests left in the current minute window
`X-RateLimit-Reset`	Unix epoch (seconds) when the minute window next frees a slot
`Retry-After`	Seconds to wait before retrying (sent on `429` only)

Example `429` Response

HTTP/1.1 429 Too Many Requests
Retry-After: 1
X-RateLimit-Limit-Second: 50
X-RateLimit-Limit-Minute: 1000
X-RateLimit-Remaining: 0
X-RateLimit-Reset: 1716624957
Content-Type: application/json

{"detail": "Rate limit exceeded. Please slow down."}

Retry Strategy

Use exponential backoff with the Retry-After header:

import time
import requests

def api_request(url, headers, max_retries=3):
    for attempt in range(max_retries):
        response = requests.get(url, headers=headers)

        if response.status_code != 429:
            return response

        retry_after = int(response.headers.get("Retry-After", 2 ** attempt))
        print(f"Rate limited. Retrying in {retry_after}s...")
        time.sleep(retry_after)

    return response  # Return last response if all retries exhausted

async function apiRequest(url: string, headers: HeadersInit, maxRetries = 3) {
  for (let attempt = 0; attempt < maxRetries; attempt++) {
    const response = await fetch(url, { headers });

    if (response.status !== 429) return response;

    const retryAfter = parseInt(response.headers.get("Retry-After") || String(2 ** attempt));
    console.log(`Rate limited. Retrying in ${retryAfter}s...`);
    await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
  }
}

# Simple retry with backoff
for i in 1 2 3; do
  response=$(curl -s -w "\n%{http_code}" \
    "https://be.graph8.com/api/v1/contacts" \
    -H "Authorization: Bearer $API_KEY")

  status=$(echo "$response" | tail -1)

  if [ "$status" != "429" ]; then
    echo "$response" | head -n -1
    break
  fi

  echo "Rate limited, retrying in ${i}s..."
  sleep $i
done

Best Practices

Use pagination with high limits - fetch 200 items per page instead of making 200 individual requests.
Watch X-RateLimit-Remaining - back off as it approaches 0 instead of waiting for a 429; X-RateLimit-Reset tells you when the window frees up.
Cache responses - if you fetch the same data repeatedly, cache it locally to reduce API calls.
Use backoff, not tight loops - when rate-limited, always respect the Retry-After header instead of retrying immediately.
