Three engines
Pick the engine your users search on, or query all three and compare. Every card links to that engine’s API page and its full reference.
The one engine here that returns its AI overview.
Web results plus images, news and instant answers, in 64 regions.
On all three
One key, one convention
POST a JSON body with a query. Each engine keeps its own field names, documented route by route.
Ads never take a position
Ads come back in their own list, so position 8 is the eighth organic result.
Page on with a cursor
Send nextCursor back with the same query and filters to read further.
JSON or markdown
Every route takes format: markdown, handy for feeding results to a model.
A notes array
Each response says when a result is narrower than you asked for.
Search URLs parsed free
resolve-url turns a results-page URL into request fields at no cost.
Side by side
Built from the API reference, not a sales sheet. A feature is only returned when the engine shows it for that query, which for most features is some of the time.

Rank tracking API
Send a query and a domain or URL. The check pages through results for you, up to 200 positions, and returns the best position, every match and the page it sits on. Ten result pages or one, you pay for one request.
Buyers increasingly ask an assistant instead of a search box, and the two rankings move independently. The AI Visibility API answers the same question for ChatGPT: where you rank in AI answers, and whether they cite you at all.

Worked example
100 keywords, all two engines, checked daily.
Full price, pay-as-you-go. 6,000 requests also fit inside the Starter plan’s 15,000 a month ($25).
Your numbers
6,000 checks = 6,000 requests
$11.94/mo
Domain or page
example.com matches the site and, by default, its subdomains. example.com/blog matches pages under that path, never /blogging.
Stops early, or scans it all
By default the check stops after the first result page with a match. Set allMatches to scan the full depth and report every position.
found: false means it looked
The whole depth was examined, or every result the engine had. On Bing and DuckDuckGo, a results page that can’t be read part-way through returns a retryable 503, never a false “not found”.
MCP & agents
One MCP server at mcp.fetchlayer.dev gives your agent 14 search tools across Bing and DuckDuckGo, next to every other FetchLayer platform. It can search, check a ranking or pull the news mid-conversation, on the same key and credits as REST. The conversation below is an illustration; the ranking in it is the real Bing rank-check example from our docs.
Pick your editor and we hand you the config with your key already in it — no JSON to hand-edit, no wrapper code.

All plansFAQ
SERP stands for search engine results page. A SERP API sends a query to a search engine for you and returns that results page as structured data: the organic results in rank order with title, URL and snippet, plus the features around them, such as People Also Ask, answer boxes, knowledge panels and top stories. Developers use one for rank tracking, SEO tools, market research and to give AI agents live web results without parsing HTML.
No. Microsoft retired the Bing Search APIs on August 11, 2025 and decommissioned existing instances. It points customers to Grounding with Bing Search in Azure AI Agents, which feeds web data into an agent’s generated answer rather than returning the results page. FetchLayer’s Bing routes return the results page itself as JSON, including Bing’s AI overview with its sources.
Not for ranked web results. DuckDuckGo publishes no API that returns its organic results list, so FetchLayer returns the results any visitor to duckduckgo.com sees, as JSON, along with news, videos, images, instant answers and suggestions.
One request per result page read, at $1.99 per 1,000 requests pay-as-you-go. A one-page search is one request; asking for more results reads more pages, and pagesScraped in the response tells you how many were billed. News, videos and images bill per list page read. Autocomplete, suggestions and instant answers are one request each, and resolve-url is free.
Exactly one request, however deep it scans: 200 positions. The response reports the result pages it read in serpPagesFetched, and that number is never billed. A deep check can take 30 seconds or more, so give your HTTP client a generous timeout.
Yes. Bing takes one of 38 markets such as en-GB or de-DE, with optional country and language overrides, on desktop or mobile. DuckDuckGo takes one of its 64 region codes, such as uk-en, or wt-wt for no region. Requests default to a US, English searcher.
Rankings depend on who is searching and when. Country, market or region, language, city and device all change the order, and so does time. Bing’s positions also move noticeably between regions and between two checks minutes apart. Your own browser adds personalisation on top. Track a query over time rather than reading one check as fixed.
Total counts: only Bing, as totalResults, when Bing shows an estimate. DuckDuckGo publishes none, so page with nextCursor until hasNextPage is false or endOfResults is true. People Also Ask: Bing returns the questions, not their answers.
No plan has a per-minute request cap: your credits or monthly allowance are the limit. Very bursty traffic waits briefly for a free slot rather than being rejected outright. Plan for latency instead: a one-page search usually answers in a few seconds, and deep rank checks take 30 seconds or more.
Yes. The FetchLayer MCP server at https://mcp.fetchlayer.dev exposes 14 search tools across the two engines, such as bing_search, duckduckgo_search and their rank checks, among 200 tools in total. Tool calls use the same key and are billed exactly like REST, so a rank check from an agent is still one request.
No. FetchLayer is not affiliated with Bing and DuckDuckGo, and is not endorsed or sponsored by them. Their names are used only to describe which search results the API returns.
