17 open-source projects still calling Bing's retired Search API

4 settings and 13 lines of code

4 projects read Bing's address from a setting: Open WebUI (env BING_SEARCH_V7_ENDPOINT), PyGPT (plugin option bing_endpoint), WebThinker and Search-o1 (CLI flag --bing_endpoint). A self-hoster sets it to https://api.specstream.ai/v7.0/search and puts a SpecStream key where the Bing key goes.

The other 13 hold the address in the line the table names. Where it is https://api.bing.microsoft.com/v7.0/search, it becomes https://api.specstream.ai/v7.0/search; where it is https://api.cognitive.microsoft.com/bing/v7.0/search, it becomes https://api.specstream.ai/bing/v7.0/search. Both paths answer, and only the host changes. A maintainer changes that line and every user moves with the next release.

What these calls reach today

Microsoft's notice says the Bing Search APIs "will be retired on August 11, 2025" and that "Any existing instances of Bing Search APIs will be decommissioned completely, and the product will no longer be available to be used or new customer signup." Each line in the table calls that retired address, and a new user of any of these projects cannot get a Bing key.

WebThinker's README says so itself: "Bing Search API will be retired in August 2025." The not working page covers what a self-hoster sees, and the retirement page has Microsoft's dates.

The same call, answered in Bing's JSON

Change the host and the key. The path, the header, the parameters and the parser stay.

# Before
curl "https://api.bing.microsoft.com/v7.0/search?q=open+source+vector+databases&count=10&offset=0" \
  -H "Ocp-Apim-Subscription-Key: $BING_KEY"

# After
curl "https://api.specstream.ai/v7.0/search?q=open+source+vector+databases&count=10&offset=0" \
  -H "Ocp-Apim-Subscription-Key: $SPECSTREAM_KEY"

The route reads q, count (1 to 50, 10 by default), offset (0 to 10,000) and freshness, and textFormat shapes the reply. Each result in webPages.value[] has id, name, url, displayUrl, snippet, isFamilyFriendly and isNavigational, and datePublished when the page has a date. dateLastCrawled and deepLinks do not come back. Every parameter and field is in the migration guide.

$5 per 1,000 searches, with no daily cap

A search of up to 10 results costs $0.005, and there is no limit per key and no daily limit. A busy call answers 429 with Retry-After and is not charged. Credit you buy never expires, and a new account gets $10 of credit, no card.

The most accurate web search API in the world

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

About one second a search

A Bing call for the first 10 results 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.

Search, pages and rows on one key

The same key reads pages with the Extract API at $0.80 per 1,000 pages. Deep Search takes a request in plain words and returns every match on the live web as rows at 5¢, 15¢ or $1 a row. A key made with zero_retention keeps no request text and no answer after the reply.

How the list was made

On November 10, 2026 we ran three GitHub code searches for Bing's v7 addresses: api.bing.microsoft.com/v7.0/search (6,048 results), api.bing.microsoft.com/v7.0/news/search (416) and api.cognitive.microsoft.com/bing/v7.0/search (447). The first two pages of each named 298 repositories. We opened the 43 with 1,000 stars or more, not archived and not forks, at their latest commit.

The table keeps the 17 whose latest commit holds Bing's address in a line we fetched and quoted. It leaves out test fixtures, documentation, comments and cached files, and it does not cover private code or forks. Stars are the count read that day. The same list for Google is 16 open-source AI apps calling Google's Custom Search.

Grounding with Bing Search

Microsoft's named replacement, a tool in Azure AI Agents at $14 per 1,000 transactions. It returns the model's answer citing publishers, and Microsoft says developers "don't have access to raw content". These projects parse a list of results. SpecStream returns that list, at $5 per 1,000.

Grounding with Bing Custom Search

The same $14 per 1,000 transactions, again with no raw content for developers. Its page sits under Agents (classic), which Microsoft retires on March 31, 2027. SpecStream answers the v7 call these projects already make.

Brave Search API

A search API on Brave's own index at $5 per 1,000 requests, with $5 in free credits every month. Brave's own migration guide says moving to it means swapping the endpoint and updating how you read the response. On SpecStream the reply is Bing's JSON, so the parser stays.
