Bing Search API key

Get a key for the same v7 call in a minute.

You can no longer get a Bing Search API key. Microsoft retired the Bing Search APIs on August 11, 2025, decommissioned every existing instance and closed new customer signup.

SpecStream answers the same v7 call at https://api.specstream.ai/v7.0/search. Create a key under Agents & API in the workspace and send it in Ocp-Apim-Subscription-Key, where your Bing key went.

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, and new accounts get $10 of credit.

New accounts get $10 of credit, no card. It covers 2,000 searches.

How to get a key and make the first call

1. Sign up at specstream.ai and open Agents & API in the workspace. A new account gets $10 of credit, no card, which covers 2,000 searches.

2. Create a key. Give it a name and, if you want one, a spending limit and zero retention.

3. Put the key where your Bing key was, and the SpecStream address where your Bing address was.

import requests

ENDPOINT = "https://api.specstream.ai/v7.0/search"  # was https://api.bing.microsoft.com/v7.0/search

reply = requests.get(
    ENDPOINT,
    headers={"Ocp-Apim-Subscription-Key": SPECSTREAM_KEY},
    params={"q": "Who founded Mistral AI and when?", "count": 10},
).json()

for page in reply.get("webPages", {}).get("value", []):
    print(page["name"], page["url"], page["snippet"])

4. Leave the rest. q, count, offset and freshness work as before, and mkt, setLang, cc and safeSearch are accepted, so the request needs no edit.

Frequently asked questions

Something we didn't answer? Talk to a human

How do I get a Bing Search API key?
You cannot since August 11, 2025, when Microsoft retired the Bing Search APIs and closed new customer signup. A SpecStream key answers the same GET /v7.0/search call at https://api.specstream.ai, and you create it in a minute under Agents & API in the workspace.
Is there a free Bing Search API key?
No. The Bing Search APIs were retired on August 11, 2025. A new SpecStream account gets $10 of credit with no card, which covers 2,000 searches on the v7 route.
Does my old Bing Search API key still work?
No. Microsoft decommissioned every existing instance of the Bing Search APIs when it retired them on August 11, 2025. Replace the key and the address, and the rest of your code stays as it is.
How much does a Bing Search API key cost in 2026?
Bing sells none since August 11, 2025, and Grounding with Bing Search costs $14 per 1,000 transactions. A SpecStream key costs nothing to create, and each search of up to 10 results costs $0.005. Every rate is on the pricing page.
Where does the SpecStream key go in a Bing request?
In the same Ocp-Apim-Subscription-Key header your Bing key used. It also works as a Bearer token or as subscription-key= in the address.
Can I limit what a key spends?
Yes. Each key takes its own spending limit in cents, for example "spend_cap_cents": 500000 for $5,000, and a call that would go over it gets a 403. Zero retention is one more field on the same key.
