# MM-REACT after the Bing Search API: one setting to change Compared on Nov 10, 2026. The page: https://specstream.ai/bing-search/mm-react MM-REACT gives ChatGPT web search through `BingSearchAPIWrapper`, which calls the Bing Web Search API v7. Microsoft retired it on August 11, 2025 and decommissioned every instance and new sign-ups, so MM-REACT's web search fails for anyone who sets it up today. MM-REACT reads its Bing address from `BING_SEARCH_URL`. Set it to `https://api.specstream.ai/v7.0/search` and put your SpecStream key in `BING_SUBSCRIPTION_KEY`. Its `BingSearchAPIWrapper` then sends its usual call to SpecStream. SpecStream answers Bing's v7 call in Bing's own JSON, scores 97.9 F-score on all 1,000 SimpleQA Verified questions and costs $5 per 1,000 searches, with no daily limit. A new account gets $10 of credit, no card.

Its own page reports 85.3% on FreshQA | ## Why MM-REACT developers point Bing search at SpecStream ### Two environment variables MM-REACT's README lists Bing as resource 4 with two variables, and its `BingSearchAPIWrapper` reads `BING_SEARCH_URL` and `BING_SUBSCRIPTION_KEY` from the environment. Before and after: ``` export BING_SEARCH_URL="https://api.bing.microsoft.com/v7.0/search" export BING_SUBSCRIPTION_KEY= ``` ``` export BING_SEARCH_URL="https://api.specstream.ai/v7.0/search" export BING_SUBSCRIPTION_KEY="$SPECSTREAM_API_KEY" unset BING_VIS_SEARCH_URL ``` Leave `BING_VIS_SEARCH_URL` unset. The wrapper calls Bing's visual search only when that variable holds an address, and otherwise runs the web search alone. ### The same request and the same JSON The wrapper sends `GET` with `q`, `count`, `textDecorations` and `textFormat`, the key in `Ocp-Apim-Subscription-Key`, and reads `webPages.value`. Its `k` is 10, so each search returns 10 results at $0.005. SpecStream answers in Bing's shape. The same call from plain Python: ``` import os, requests reply = requests.get( "https://api.specstream.ai/v7.0/search", headers={"Ocp-Apim-Subscription-Key": os.environ["SPECSTREAM_API_KEY"]}, params={"q": "who painted the girl with a pearl earring", "count": 10}, ).json() for page in reply["webPages"]["value"]: print(page["name"], page["url"], page["snippet"]) ``` Every parameter and field of the route is in the [Bing Web Search v7 guide](https://specstream.ai/migrate/bing-web-search-v7?utm_source=alternatives&utm_campaign=bing-search-mm-react), and what Microsoft ended, and when, is on the [Bing Search API retirement](https://specstream.ai/bing-search-api-retirement?utm_source=alternatives&utm_campaign=bing-search-mm-react) page. ### $5 per 1,000 searches, with no daily limit A search of up to 10 results costs $0.005. There is no monthly plan and no daily limit. Credit you buy never expires, and a new account starts with $10 of credit, which covers 2,000 searches. A busy call gets a `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](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=bing-search-mm-react) page. Every Bing call 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. There is no limit per key and no daily limit. ### 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, so a long MM-REACT run stops at the cap you set. ``` 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](https://specstream.ai/extract-api?utm_source=alternatives&utm_campaign=bing-search-mm-react) at $0.80 per 1,000 pages, and a page with no text is not charged. [Deep Search](https://specstream.ai/deep-search?utm_source=alternatives&utm_campaign=bing-search-mm-react) 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. ## Other web search options for MM-REACT ### Grounding with Bing Search Microsoft's named replacement for the Bing Search APIs, at $14 per 1,000 transactions, inside Azure AI Agents. It returns an answer with citations, and developers get no access to the raw results, so MM-REACT's `BingSearchRun` tool has no `webPages.value` to read. SpecStream returns Bing's `webPages.value[]` at $5 per 1,000. ### Google Custom Search JSON API $5 per 1,000 queries after 100 free a day, up to 10,000 a day, for existing customers only: Google closed it to new customers and ends it on January 1, 2027. It answers a different request with a different reply. SpecStream keeps MM-REACT's Bing call and costs the same $5 per 1,000, with no daily limit. ### Brave Search API A search API on Brave's own index at $5 per 1,000 requests, with $5 in free credits every month and up to 50 queries a second. MM-REACT has no Brave setting, so moving there means new code. SpecStream answers the Bing call MM-REACT already makes, at the same $5 per 1,000. ## How to move MM-REACT web search to SpecStream 1. Create a key under Agents & API in the SpecStream workspace. A new account gets $10 of credit, no card, which covers 2,000 searches. 2. Check the key with the call Bing's v7 API takes. A `200` with `webPages.value` means the key works. ``` curl -H "Ocp-Apim-Subscription-Key: $SPECSTREAM_API_KEY" \ "https://api.specstream.ai/v7.0/search?q=test&count=3" ``` 3. Set the two variables in the shell that starts `sample.py`, and leave the visual search address empty: ``` export BING_SEARCH_URL="https://api.specstream.ai/v7.0/search" export BING_SUBSCRIPTION_KEY="$SPECSTREAM_API_KEY" unset BING_VIS_SEARCH_URL ``` 4. Run `python sample.py` as before. Each search shows in your SpecStream request log with its price. ## Frequently asked questions ### Why is MM-REACT Bing search not working? Microsoft retired the Bing Search APIs on August 11, 2025 and decommissioned every instance, so the address in MM-REACT's README answers nothing. Set `BING_SEARCH_URL` to `https://api.specstream.ai/v7.0/search` with a SpecStream key in `BING_SUBSCRIPTION_KEY`. ### Where do I get an MM-REACT Bing API key now? Not from Microsoft: Bing has taken no new customer sign-up since August 11, 2025. Create a SpecStream key with $10 of credit, no card, and export it as `BING_SUBSCRIPTION_KEY`. ### What does BING_SEARCH_URL take? The full search address: `https://api.specstream.ai/v7.0/search`. The wrapper adds `q` and `count` itself. ### What is the best MM-REACT Bing alternative? SpecStream, at $5 per 1,000 searches with no daily limit and 97.9 F-score on all 1,000 SimpleQA Verified questions. It answers the Bing call MM-REACT already makes. ### Which MM-REACT Bing variable do I leave empty? `BING_VIS_SEARCH_URL`. With it unset the wrapper skips Bing's visual search and runs the web search, which SpecStream answers at $0.005 a call of 10 results. ### How much does MM-REACT web search cost with SpecStream? $0.005 a search of 10 results, the wrapper's default `k`. The first $10 of credit covers 2,000 searches, and credit you buy never expires. ## Sources SpecStream wrote this page.
