Web search for your AI app
Paste one address in one setting.
Eight apps take SpecStream as their web search with one setting changed, tested on production on November 9, 2026: Open WebUI, LibreChat, AnythingLLM, GPT Researcher, Dify, n8n, Agno and LangChain.
Most read SpecStream as a SearXNG instance you never host: paste the address from the table, with your key in it, where the app asks for its SearXNG URL. Open WebUI takes it as its external search.
It is the most accurate web search API in the world: 97.9 F-score on all 1,000 SimpleQA Verified questions, on the benchmarks page. A search costs $0.005, which is $5 per 1,000.
New accounts get $10 of credit, no card. It covers 2,000 searches.

What your app gets from SpecStream
The app sends its SearXNG call, and SpecStream answers it
This is the call LibreChat, GPT Researcher, n8n, Agno and the others send once the address is set. Try it with your key before you change the app.
curl "https://api.specstream.ai/searxng/$SPECSTREAM_API_KEY/search?q=who+founded+Mistral+AI&format=json"The reply is SearXNG's JSON: results[] with title, url and content, the fields these apps read. Each call is one search of 10 results at $0.005.
No instance to run
A SearXNG you host needs json under search.formats in its settings.yml before an app can read it, and a server to keep running. The SpecStream address answers JSON from the first call and searches the whole live web at the second of the call, with nothing to install.
The key travels in the address, so apps that send no key for SearXNG still sign their calls. It also goes in key=, an X-API-Key header or a Bearer token where the app has a key field.
$0.005 a search, and a failed call costs nothing
A search of up to 10 results costs $0.005, which is $5 per 1,000. Each started block of 10 more results adds $0.006, up to 100 results a search. A call stopped by a 429 charges nothing, and a top-up never expires.
A new account gets $10 of credit with no card, which covers 2,000 searches.
The most accurate web search API, at about one second a call
The SpecStream Search API scores 97.9 F-score on all 1,000 SimpleQA Verified questions, 978 of them correct, and 64.0 item F1 and 43.4 row F1 on all 200 WideSearch tasks. The Extract API scores 0.908 F1 on WCXB. The method and each score are on the benchmarks page.
A drop-in call for the first ten results, without page text or the answer, runs the fast search. On November 9, 2026 production answered 718 of 720 searches at 1 to 20 a second, with a median of 0.82 s at 1 a second and 1.07 s at 20 a second, and the 95th percentile between 1.09 and 1.73 s. One account takes up to 8,800 searches a minute; a call over that gets a 429 with Retry-After and is not charged.
No query text is kept on a zero retention key
Create a key with zero_retention and a search made with it keeps no request text and no answer after the reply, in the history or in a log line. 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}'Pages and finished rows on the same 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.

How to set it up
1. Create a key under Agents & API in the workspace. A new account gets $10 of credit, no card, which covers 2,000 searches.
2. Check the address with your key. A 200 with results means the app will get the same reply:
curl -s -o /dev/null -w '%{http_code}\n' "https://api.specstream.ai/searxng/$SPECSTREAM_API_KEY/search?q=test&format=json"3. Paste the value from the table into your app's setting, with your key in place of <key>, and ask the app a question that needs the web. The page for your app has each step.
