SerpApi compatible

The call, before and after

# Before
curl "https://serpapi.com/search.json?engine=google&q=Larkspur+Colorado+mayor&api_key=$SERPAPI_API_KEY"

# After
curl "https://api.specstream.ai/serpapi/search.json?engine=google&q=Larkspur+Colorado+mayor&api_key=$SPECSTREAM_API_KEY"

With SerpApi's Python client, serpapi 1.2.0, the change is one line after the client is made. search and next_page() work as before.

import serpapi

client = serpapi.Client(api_key=SPECSTREAM_KEY); client.BASE_DOMAIN = "https://api.specstream.ai/serpapi"
results = client.search({"engine": "google", "q": "Larkspur Colorado mayor"})
for result in results["organic_results"]:
    print(result["position"], result["title"], result["link"])

Apps and SDKs that take the address as a setting

Each line was run on production on November 10, 2026 through that client's own request and reply code. Put your SpecStream key wherever the client takes its key.

The older google-search-results Python package (2.4.2): set GoogleSearch.BACKEND = "https://api.specstream.ai/serpapi" before the first search.

What the route reads, and what it refuses

Read and applied: q, engine google, num (1 to 100), start, tbs with qdr: or cdr: dates, api_key, and the client's next_page(), which follows serpapi_pagination.next.

Refused with 400: tbm (news, images and the other tabs) and any engine other than google. A call with no key gets 401. Every parameter was measured on production on Nov 10, 2026 with serpapi 1.2.0, and the full pass table lists each one and its result.

Every field that comes back

The reply has search_metadata with id, status, created_at, processed_at and total_time_taken, search_parameters with engine and q, search_information with organic_results_state, query_displayed, total_results and time_taken_displayed, organic_results[], and serpapi_pagination with current, next_link and next.

The route does not return answer_box, knowledge_graph, related_questions, local_results, top_stories, related_searches, search_metadata.json_endpoint, google_url or raw_html_file, or a result's redirect_link, thumbnail, favicon, snippet_highlighted_words, sitelinks and source. One field is added, specstream, with the call's price_usd.

$5 per 1,000 searches, with no monthly plan

On SerpApi, 1,000 searches a month cost $25 on Starter and 5,000 cost $75 on Developer, each with an hourly limit. On SpecStream every call of up to 10 results costs $0.005, each started block of 10 more adds $0.006, and credit you buy never expires. A busy call gets 429 with Retry-After and charges nothing.

The most accurate web search API, in about one second

On SimpleQA Verified the SpecStream Search API scores 97.9 F-score on all 1,000 official questions, 978 of them correct. On WideSearch it scores 64.0 item F1 and 43.4 row F1 on all 200 official tasks. The Extract API scores 0.908 F1 on WCXB. Every score and its method is on the benchmarks page.

A call of up to 10 results on the first page runs the fast search. Measured on production on November 9, 2026, its median was 0.82 s at 1 search a second and 1.07 s at 20 a second, the 95th percentile stayed between 1.09 and 1.73 s, and it answered 718 of 720. One account can send up to 8,800 searches a minute.

You decide what is kept, on each key

Create the key with zero_retention and a search made with it keeps no request text and no answer after the reply. spend_cap_cents is the most the key can spend.

curl -X POST https://api.specstream.ai/v1/account/keys \
  -H "Authorization: Bearer $SPECSTREAM_API_KEY" -H "Content-Type: application/json" \
  -d '{"name": "production", "scopes": ["account:read", "finds:spend"], "spend_cap_cents": 500000, "zero_retention": true}'

Search, pages and rows on one key

The same key reads up to 20 pages or documents 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 for a request in plain words as structured rows, at 5¢, 15¢ or $1 a row, with a source URL on every value. The most a run can cost is approved before it starts. The full comparison is on the SerpApi alternative page.
