Best SERP APIs in 2026

Four things a buyer checks

Each API was ranked on the price of a live search at 10,000 and 100,000 searches a month, whether money is paid ahead or runs out, the speed and volume its own page publishes, and the accuracy it publishes. Every rival figure in the table comes from that company's pricing page or docs, read on Nov 12, 2026, and is linked in the sources at the end. SpecStream's figures come from its own measurements on production, with the method on the benchmarks page.

The most accurate web search API in the world

On SimpleQA Verified the SpecStream Search API scores 97.9 F-score on all 1,000 official questions, 978 of them correct, and every raw answer is public. SerpApi prints a score on the same set on its own blog: 97.6%, 937 correct of the 960 questions left after it set aside 40. On WideSearch SpecStream scores 64.0 item F1 and 43.4 row F1 on all 200 official tasks.

$1 per 1,000 with nothing paid ahead

Serper and Scrapingdog list lower prices at volume, and both are paid ahead: Serper's $0.30 needs a $3,750 pack used within 6 months, and Scrapingdog's $0.45 is a $90 monthly plan. SerpApi costs $725 for 100,000 searches a month and resets unused searches at each renewal. SpecStream charges $0.001 a search from the first one, bills only calls that return results, and credit you buy never expires.

About one second a search, measured under load

Every drop-in address runs on the fast search. On November 9, 2026 production took 1, 5, 10 and 20 fast searches a second and answered 718 of 720. The median was 0.82 s at 1 search a second and 1.07 s at 20 a second, and the 95th percentile stayed between 1.09 and 1.73 s. A busy call gets a 429 in the API's own error form with Retry-After, and is not charged.

Run the test yourself

Send the same five queries from your logs to your provider and to SpecStream, then compare the links. The test below needs jq and costs $0.005 on SpecStream, inside the $10 of credit a new account gets.

for q in "best running shoes" "postgres 17 release date" "crm for small business" "eu ai act fines" "stripe api rate limit"; do
  echo "== $q"
  curl -s https://google.serper.dev/search -H "X-API-KEY: $SERPER_KEY" -H "Content-Type: application/json" -d "{\"q\": \"$q\"}" | jq -r '.organic[:5][].link'
  curl -s https://api.specstream.ai/serper/search -H "X-API-KEY: $SPECSTREAM_KEY" -H "Content-Type: application/json" -d "{\"q\": \"$q\"}" | jq -r '.organic[:5][].link'
done

For SerpApi, swap the two lines for https://serpapi.com/search.json and https://api.specstream.ai/serpapi/search.json with engine=google and api_key, and read .organic_results[:5][].link.

What comes back

Each search is read from the live web at the moment of the call and ranked by SpecStream, then written in the JSON of the API your code calls: organic[] for Serper, organic_results[] for SerpApi and SearchApi, tasks[].result[].items[] for DataForSEO. Up to 100 results come back with num; each started block of 10 more adds $0.0012. On GET /v1/web-search, the reply also holds the answer with the page it was read on and its read time, at $5 per 1,000.

For agents: MCP and pages on the same key

Agents connect to https://api.specstream.ai/mcp, with search_web and read_pages. The same key reads up to 20 pages a call with the Extract API at $0.80 per 1,000 pages, and a page with no text is not charged. Deep Search returns every match on the live web as structured rows at 5¢, 15¢ or $1 a row.

VALUE SERP

Traject Data's SERP API, at $2.50 per 1,000 pay as you go with 100 free requests, or $158 a month for 100,000 searches billed annually. SpecStream answers its call at https://api.specstream.ai/valueserp at $1 per 1,000 (the move).

HasData

A scraping company that lists its Google SERP API at $0.83 per 1,000 requests on its pricing page. SpecStream sells searches with no plan, at $1 per 1,000, and its credit never expires.
