TL;DR — SerpAPI and ODEN look similar but answer different questions. SerpAPI gives you structured search-engine results (Google, Bing, and dozens more) — the SERP as JSON, including ads, related searches and rich results. ODEN gives you a synthesized answer plus citations built for a model's context window. Choose SerpAPI if you need the raw SERP or SEO/rank data; choose ODEN if you want an answer an LLM can use directly.
SerpAPI is a search-engine-results API: it runs a query against Google (or Bing, Baidu, YouTube, Google Maps, and more) and returns the results page as clean, structured JSON. ODEN is a retrieval-and-synthesis API for LLMs: it searches, reads the sources, and returns a distilled answer with the citations behind it.

|---|---|---|
| Primary output | Synthesized answer + ranked citations | Structured SERP JSON (organic, ads, rich results) |
| Reads and distills the sources | Yes | No — returns the results page, not page contents |
| Built for | LLM context / RAG / agents | SEO tools, rank tracking, SERP scraping |
| Engines | The open web, one pipeline | Google, Bing, Baidu, YouTube, Maps, and more |
| Hosting | EU (Cloudflare, Sweden) | United States |
| robots.txt + EU TDM opt-out at source | Yes | Not the model — it fetches SERPs |
| Pricing model | Flat monthly quota + never-expiring top-ups | Paid searches per plan |
| Free tier | 1,000 searches/month | Limited monthly free searches |
Where SerpAPI is ahead#
If you actually need the search-engine results page — organic rankings, ad placements, "people also ask", knowledge panels, or results from a specific engine or locale — SerpAPI is purpose-built for it and covers far more engines and result types than ODEN does. For SEO tooling, rank tracking and SERP analysis, ODEN is the wrong tool and SerpAPI is the right one.
Where ODEN is ahead#
For feeding an LLM, SerpAPI leaves you with more work: you get links and snippets, then you still have to fetch each page, strip the HTML, extract the relevant passage and rank it. ODEN does that server-side and hands you the answer plus citations in one call — fewer round trips, fewer tokens, less glue code. ODEN is also EU-hosted and checks robots.txt and the EU TDM opt-out at the source, which a SERP-scraping model does not aim to do.
Pricing head-to-head#
ODEN: Free 1,000 searches/month, Pro €29/month for 6,000, top-ups €7 per 1,000 that never expire. See pricing.
SerpAPI charges for a monthly number of searches across paid plans, with a small free allowance. Because plans and per-search costs change, check SerpAPI's current pricing directly. The structural point: with SerpAPI you also pay — in tokens and engineering — for the extraction step ODEN includes.
When to choose which#
- Choose SerpAPI if you need the raw SERP, many engines/locales, or SEO and rank-tracking data.
- Choose ODEN if you want a clean, synthesized answer with citations for an LLM, EU hosting, and no separate scrape-and-extract step.
FAQ#
Does SerpAPI return a synthesized answer?#
No. SerpAPI returns the structured search-results page. Turning that into an answer — fetching pages, extracting text, ranking passages — is your job. ODEN returns the answer and citations directly.
Can I use SerpAPI for RAG?#
You can, but you build the retrieval pipeline yourself on top of the SERP. ODEN is designed for RAG out of the box: one call returns context-ready text.
Is ODEN a SERP scraper?#
No. ODEN does not return the search-results page or SEO data. If that is what you need, use SerpAPI. ODEN reads the open web and returns a distilled answer with sources.
