Pricing
Save up to 80% versus using the providers directly
Plans differ only in volume. Domain Rating, both traffic estimates, keywords, SERP and index checks are included from the free tier up — and cached lookups never cost a credit.

Credits per call
A credit is one billed provider call, weighted by the API type it belongs to; most types cost 1 credit per call. On the vendor data routes an Ahrefs call counts once per 50-unit block of its own cost. The dollar column is an estimate on the Basic plan ($5 for 4,000 credits) — every larger plan costs less per call.
| API type | Credits per call | ≈ per 1,000 calls |
|---|---|---|
| Ahrefs data Domain Rating, Ahrefs Rank, organic traffic, keyword volume and difficulty — per call on the core routes · per 50-unit block on /v1/ahrefs | 1 | $1.25 |
| SimilarWeb data Total visits, engagement, top countries and popularity ranks | 1 | $1.25 |
| Moz data Domain Authority, Page Authority and spam score | 1 | $1.25 |
| Semrush backlinks Backlink and referring-domain counts | 1 | $1.25 |
| SERP data Google result pages and keyword rankings | 1 | $1.25 |
| Google index checker Whether a URL is in Google's index | 1 | $1.25 |
| Noindex checker HTTP status, redirects, noindex and nofollow for one URL | 1 | $1.25 |
| Link indexing — standard Submit URLs to be crawled and indexed, standard queue | 100 | $125 |
| Link indexing — advanced Submit URLs to be crawled and indexed, priority queue (up to 100 URLs, minutes not days) | 200 | $250 |
| Favicon lookup A verified favicon URL for a domain | 1 | $1.25 |
Cached answers cost 0 credits whatever the type. The table is read live from the API, so it always shows the current costs.

FAQ
Small, credit-based plans that start at $5 a month, and all the APIs in one place — Ahrefs, Similarweb, Moz, SERP and indexing data under one key — without a corporate-level contract, a per-vendor minimum or an annual commitment. The providers' own API access is priced for enterprises: hundreds of dollars a month, often behind a sales call (published entry prices as of August 2026; check their sites for current figures). What's cheaper is the packaging and the commitment, never the data — every number is the provider's own figure, named on it, and cached answers cost nothing.
On the core routes a credit is one fresh lookup, at the credits its API type costs (1 for most types — the
table above lists the exceptions). A domain lookup spends one credit per
field group it has to fetch fresh, so it depends on what you ask for:
fields=rating costs 1, fields=rating,traffic costs 3, and the default
rating,traffic,countries costs 4. Anything answered from our shared cache costs
zero — and popular domains are usually cached. Your /v1/usage
endpoint shows the running total in real time.
The vendor data routes — /v1/ahrefs/… and
/v1/similarweb/overview — are priced by what the vendor bills us. An Ahrefs call costs the
Ahrefs credits per 50-unit block of its own cost, and the Similarweb overview is one call. Before the call
we reserve its worst case — its row limit times every field's cost — and you are
never charged more than that reservation. Cached answers cost 0. At 1 credit per call:
select=all (92 units) — 2 creditsurl_from,url_to,anchor,domain_rating_source,traffic (14 units a row, 1,400 units) — 28 creditsMonthly plan credits reset every month on the day you signed up (00:00 UTC) — your dashboard shows the date. Prepaid pack credits last 12 months — that's what packs are for.
Requests answer 429 quota_exceeded with a clear message; nothing silently degrades and nothing is billed as overage. Upgrade, add a pack, or wait for the reset.
Yes. Plans buy volume and rate, never data quality. The free tier reads the same providers the Scale tier does.
Every plan starts as a free key. Upgrade when the quota tells you to.
