Semrush API Pricing Explained (2026) — and 6 Cheaper Alternatives

Here's the answer you searched for, up front. As of September 2026, getting access to the Semrush API works like this:

1. You buy the Advanced plan: $549/mo (or $455.67/mo billed annually, ~$5,468/year). Lower plans — Pro, Guru — do not include API access.
2. That plan includes zero API units. The subscription is the ticket in, not the meter.
3. You then buy API units separately, in packages of 2M, 5M, 10M, or 20M units. The package prices aren't published — it's contact-sales. Third-party estimates put it around $50 per 1M units, but treat that as an estimate, because Semrush won't print a number.

So the minimum realistic first month is $549 plus a unit package you have to email sales to price — before your first API call returns a byte. That's the most expensive and most opaque entry in the SEO API market, and it's why "Semrush API pricing" is a question people ask twice: once at the pricing page, and again in disbelief.

For contrast: RankParse's first invoice is $0 (100 free credits, no card) or $10 for 1,000 credits at published, flat per-endpoint prices. This post walks through how Semrush units work, what the real alternatives cost, and — honestly — when Semrush is still the right buy. (For the API's design and data on their own merits, see the Semrush API review; for getting your data out, how to export data from Semrush.)

How Semrush API units actually work

Every Semrush API call burns units, and the burn rate varies by endpoint and by rows returned — a backlinks report line costs a different amount than a keyword report line. Units come from the packages above, purchased on top of the Advanced plan, and the pricing for those packages lives behind a sales conversation.

Two more wrinkles worth knowing:

• The legacy path still haunts the docs. Semrush's older Business plan ($499.95/mo) with API access is still referenced in documentation and third-party guides. The current path for new customers is Advanced + separately purchased units. If you find a page quoting $499.95/mo as "the Semrush API price," it's describing the old world.
• The Adobe factor. Adobe's acquisition of Semrush (announced late 2025) has generated a steady stream of roadmap-uncertainty commentary in the SEO community. Nobody outside the companies knows what it means for API pricing or continuity — we won't speculate either — but if you're signing a five-figure annual commitment, it's a fair question for your sales rep.

The alternatives, compared

Every row above has published pricing except the one you came here to research. That's the story.

1. RankParse — pay-as-you-go domain intelligence

RankParse covers the backlink and domain-intelligence slice of what people pull from the Semrush API: backlinks, referring domains, anchor text, domain authority, link intersect, tech stack. Pricing is prepaid credits — $10/1,000 ($0.010), $80/10,000 ($0.008), $600/100,000 ($0.006) — with flat published credit costs per endpoint (1 credit for domain authority, 2 for backlinks) and credits that never expire. MCP server included on the free tier for Claude/ChatGPT/Cursor agents.

The honest scope note: RankParse does not have Semrush's keyword database, position tracking, or traffic analytics. If those are what you call the Semrush API for, RankParse isn't your replacement — DataForSEO or SE Ranking is. If you call it for link and domain data, RankParse does that job for a rounding error of the price. Head-to-head: RankParse vs Semrush.

2. DataForSEO — the broad PAYG workhorse

The closest thing to full Semrush API coverage without a subscription: SERP, keywords, backlinks, on-page, and more, priced per request with published rates (backlinks: $0.024/task + $0.000036/row, ~$0.06 per 1,000-row pull; SERP from $0.60/1K queued). $50 minimum top-up, balance never expires. The tradeoff is integration overhead — Basic Auth, POST task arrays, nested response envelopes. Full comparison: RankParse vs DataForSEO.

3. SE Ranking Data API — breadth on an annual contract

Backlinks + keywords + SERP + AI-visibility in one API for $2,148/year (12M credits), annual only. Much cheaper than Semrush Advanced + units for comparable breadth, but still a commitment, not pay-as-you-go. Head-to-head: RankParse vs SE Ranking Data API.

4. Serpstat — the budget suite with an API attached

API access from the Team plan at $100/mo (200–400K credits/mo). The cheapest way to get keyword-and-domain API data bundled with a working suite; the indexes are smaller than Semrush's, and the API is tied to platform seats.

5. Moz API — predictable rows for authority metrics

A real free tier (~50 rows/mo), then $20/mo for 3,000 rows upward. The simplest billing on this list and the industry-default DA metric; a much smaller data scope than Semrush. See RankParse vs Moz.

6. Majestic — links only, $399.99/mo

Full API access at $399.99/mo (100M analysis units) buys deep historic link data and Trust Flow. Nothing else — no keywords, no SERP. See RankParse vs Majestic.

The worked scenario: a domain-intelligence workload

Say your product needs backlink profiles and authority scores for 2,000 domains a month (one backlinks pull + one DA lookup each — 6,000 RankParse credits):

• Semrush: $549/mo Advanced + a unit package (contact sales; third-party estimates start around $50/1M units). Realistically $600–1,000+/mo, and you can't know precisely until you've asked.
• SE Ranking: $2,148/year contract = $179/mo effective, if the annual shape fits.
• DataForSEO: 2,000 × ~$0.06 = ~$120/mo for the backlink pulls alone, after the $50 minimum top-up.
• RankParse: 6,000 credits ≈ $48/mo at the Growth rate ($80 pack lasts ~7 weeks) — and in a month where the pipeline doesn't run, you spend $0, because credits never expire.

Model your own volume on the pricing calculator.

When Semrush is still the right call

• Your team already pays for Advanced. Then the subscription gate is sunk cost and units are the only marginal spend — the calculus changes completely.
• You need the keyword database. Semrush's keyword and competitive-intelligence data is the product's crown jewel, and none of the link-focused alternatives here replicate it. (DataForSEO and SE Ranking come closest.)
• Enterprise procurement wants one throat to choke. A single vendor covering suite + API + reporting has organizational value that per-call pricing doesn't capture.

If none of those apply — if you're a developer who just needs SEO data in a pipeline — you're the customer the $549 gate was built to filter out. Take the hint and pay per call instead.

FAQ

How much does the Semrush API cost in 2026?

You need the Advanced plan ($549/mo, or $455.67/mo billed annually), and API units are purchased separately in 2M–20M packages with unpublished, contact-sales pricing (~$50 per 1M units per third-party estimates). Minimum first month: $549 plus a unit package.

Does the Semrush Advanced plan include API units?

No. Advanced unlocks the ability to buy API units; it includes none. This is the detail that surprises almost everyone.

Is there a free Semrush API tier?

No. There's no free tier, no trial units, and no pay-as-you-go option for the Semrush API.

What are the cheapest Semrush API alternatives?

For link and domain data: RankParse (from $0.006/credit, no subscription). For broad SERP/keyword/backlink coverage: DataForSEO (PAYG, $50 minimum) or SE Ranking's Data API ($2,148/year). For simple authority metrics: Moz ($20/mo) or OpenPageRank (free, 1K req/day).

What does the Adobe acquisition mean for Semrush API users?

Unknown. The acquisition (announced late 2025) has produced plenty of commentary about roadmap and pricing uncertainty, but no announced API changes as of September 2026. If you're committing to an annual contract, ask directly.

Can I get backlink and domain data pay-as-you-go instead?

Yes. RankParse sells exactly that: 100 free credits, then packs from $10, flat published credit costs per endpoint, credits that never expire, and an MCP server for agent workflows. That's the entire pitch — the pricing page is one table long.
