A rank checker answers a focused question: right now, where does this domain rank for this keyword? The rank checker API turns that into a single call — request the SERP, find the domain, return the position. No login, no dashboard, no waiting on a nightly crawl.

It is ideal for on-demand checks: a user pastes a keyword and URL into your tool and gets the live rank instantly. At $0.30 per 1,000 checks, even a high-traffic rank-checking feature stays cheap to run.

Get started in one request

A rank check is one request: fetch the SERP, find the domain, read its position.

curl "https://api.searlo.tech/api/v1/search/web?q=best%20vpn&num=10" \
  -H "x-api-key: YOUR_API_KEY"
import requests

r = requests.get(
    "https://api.searlo.tech/api/v1/search/web",
    params={"q": "best vpn", "num": 10},
    headers={"x-api-key": "YOUR_API_KEY"},
)
results = r.json()["organic"]
# position of your domain in the SERP
rank = next(
    (o["position"] for o in results
     if "yourdomain.com" in o["domain"]),
    None,
)
print("rank:", rank)
const res = await fetch(
  "https://api.searlo.tech/api/v1/search/web?q=" +
    encodeURIComponent("best vpn") + "&num=10",
  { headers: { "x-api-key": "YOUR_API_KEY" } },
);
const { organic } = await res.json();
const rank = organic.find(o =>
  o.domain.includes("yourdomain.com"))?.position ?? null;
console.log("rank:", rank);

On-demand vs scheduled rank checking

A rank checker API serves two patterns. On-demand: a user triggers a check and you call the endpoint live, returning the position immediately. Scheduled: you run checks on a cron and persist the results to build history. The same endpoint covers both.

Because there are no keyword caps, you can expose unlimited interactive checks to users and only pay for the queries actually run.

  • Interactive 'check my rank' features
  • Scheduled rank history collection
  • Competitor position spot-checks
  • Local rank verification by city/country

What does a rank check cost?

Each check is one query at $0.30 per 1,000, with 3,000 free credits to start and no per-keyword fees.

Can I check competitor rankings too?
