SerpAPI is a focused Google SERP wrapper agents have leaned on for years. UnifAPI bundles SERP with TikTok, LinkedIn, Reddit, YouTube, Twitter, Instagram, and more behind one key.

SerpAPI is a search-engine specialist: it wraps Google, Bing, Baidu, Yandex, and a handful of others behind one tidy JSON shape and has been the default SERP API for years. UnifAPI is a public-data generalist: SERP is one slice, alongside social platforms, web scrape, and news, billed at a flat $0.001 per record across all of them. If your agent only ever needs a Google query, SerpAPI is excellent. If it needs anything else from the open web, the math changes.

What SerpAPI does well

SerpAPI is narrow on purpose. Google SERP scraping is hard — the page shape changes constantly, geo-targeting matters, knowledge panels and featured snippets need parsing — and a focused team has been polishing that one slice for years. The result is one of the most reliable SERP wrappers on the market, with structured outputs for organic results, ads, knowledge graphs, related searches, and the long tail of Google features.

If your agent's value is entirely about Google results — rank tracking, SERP feature monitoring, position-on-keyword analytics — SerpAPI is mature and dependable.

Where SerpAPI ends, UnifAPI begins

Most agents don't stay inside Google. They land on a SERP, then they want to read the actual tweet, watch the YouTube video the result links to, pull the Reddit thread, hit the LinkedIn profile, or scrape the article. Each of those is a separate integration on SerpAPI's side — you have to leave it.

UnifAPI is the version where you don't leave. The catalog covers 14 live social platforms today (TikTok, LinkedIn, Instagram, YouTube, Twitter/X, Threads, Reddit, plus seven Chinese platforms), with Google + Bing SERP, URL-to-markdown scrape, and news search on the roadmap. Same key, same envelope, same per-record price.

Pricing comparison

SerpAPI sells search-by-volume plans: 100 free / month, then $50 for 5,000 searches, scaling up from there. Caps are tier-based; overage requires an upgrade. Each search returns a SERP page, not a per-record count.

UnifAPI is $0.001 per record returned. A Google SERP call that comes back with 10 organic results costs $0.01. There's no per-month minimum, no tier ladder, no cap. The 1,000 free records grant gives you about 100 SERP calls — enough to evaluate.

For pure SERP workloads, SerpAPI's plan-based pricing can be cheaper at scale; for mixed workloads where SERP is one input among many, UnifAPI's flat rate avoids the multi-vendor billing tax.

Migration path

If you've already built on SerpAPI, the lift to UnifAPI is small. Our SERP endpoints return the same primitives — organic results, knowledge graph, related searches — under a uniform envelope. The harder part of the migration is usually adding the social and scrape calls you'd been deferring; once those are one key away, agents tend to grow into them.

Pick SerpAPI if Google is the entire product. Pick UnifAPI if Google is one step in a larger agent loop and you want the rest of the open web behind the same auth header.
