Devika

Give Devika's research step a working Bing engine. Set the BING endpoint to SpecStream's Bing format address and the BING key to your SpecStream key, in Devika's settings or in config.toml, and choose Bing for the project. Devika's code stays as it is.

SpecStream for DevikaCoding agents

What you need

  • Devika running as its README shows: python devika.py for the backend, and bun run start in ui for the interface at http://127.0.0.1:3001.
  • A SpecStream key. Get your key on the Search API screen of your SpecStream workspace. New accounts start with $10 of credit, no card.

  1. 1. Set the Bing endpoint

    Open Settings in Devika's sidebar, then the API Endpoints tab. Click Edit, replace the address in the bing field with SpecStream's, and click Save.

    bing
    https://api.specstream.ai/v7.0/search

  2. 2. Set the Bing key

    On the API Keys tab, click Edit, put your SpecStream key in the bing field, and click Save. Devika sends it in the Ocp-Apim-Subscription-Key header, where SpecStream's Bing route reads it.

    To edit the file instead, set both lines in config.toml in Devika's root folder, then restart python devika.py, which reads the file when it starts:

    config.toml
    [API_KEYS]
    BING = "YOUR_SPECSTREAM_KEY"
    

    [API_ENDPOINTS]
    BING = "https://api.specstream.ai/v7.0/search"

  3. 3. Choose Bing for the project

    In the control panel, open the search engine menu, which lists Bing, Google and DuckDuckGo, and choose Bing. Devika sends the choice with each message, so it applies from your next one.

  4. 4. Give Devika a task that needs research

    Ask for something that needs current documentation. Devika's researcher writes up to 3 search queries for the step, searches each one through SpecStream, opens the first result in its own browser and reads that page into its context. The terminal running python devika.py prints Search Engine :: bing for the step.

    In the Devika chat
    Write a Python script that lists my open GitHub issues with the GitHub REST API.

What Devika sends and gets back

BingSearch.search sends one GET to the BING endpoint for each query. SpecStream answers in Bing Web Search v7's shape, and Devika reads one field from the reply: the url of the first result in webPages.value.

Why the Bing engine needs a new address

Microsoft retired the Bing Search APIs on August 11, 2025. The https://api.bing.microsoft.com/v7.0/search address in Devika's sample.config.toml gets no results today, and the Azure steps in Devika's search engine guide no longer give a key. SpecStream answers the same v7 call, so Devika's Bing code works with only the endpoint and the key changed. Moving off Bing Web Search v7 has the settings for other Bing clients.

The engine that needs no key, DuckDuckGo, reads duckduckgo.com's own pages, and Devika's DuckDuckGo class carries the note "currently, the package is not working with our current setup."

SpecStream's search API scores 97.9 F-score on all 1,000 SimpleQA Verified questions and 64.0 item F1 on all 200 WideSearch tasks. Scores and method are on the benchmarks page.

Or use the Google engine

Devika's Google engine moves the same way. SpecStream answers Google's Custom Search JSON API call in Google's shape, and Devika reads items[0].link. Set the google endpoint to https://api.specstream.ai/customsearch/v1, put your SpecStream key in google_search, put any value in google_search_engine_id (SpecStream accepts cx and does not use it), and choose Google in the menu.

Google ends its Custom Search JSON API for existing customers on January 1, 2027. Moving off Google Custom Search has the details.

What each search costs

  • Each query is one Search API call through a drop-in address: $1 per 1,000 searches of up to 10 results. A search that returns no results costs nothing.
  • The researcher writes at most 3 queries a step, so a research step costs at most 3 searches.
  • Devika opens the first result in its own browser. SpecStream does not read that page, so it adds nothing to the bill.
  • Calls come out of your balance with no quote and no approval, and every call is in your account's request log. New accounts start with $10 of credit, no card.

Limits and errors

  • With a wrong key SpecStream answers 401. Devika's BingSearch then holds no result, and the step stops with a Python error in the terminal running python devika.py. Check the bing key.
  • When the account has used its calls for the minute, SpecStream answers 429 with Retry-After, and nothing is charged. Devika does not retry, so send the message again after that wait.
  • If the terminal prints another engine than bing, the menu still holds that engine. Choose Bing and send the message again.

Go back

Set the bing endpoint back to https://api.bing.microsoft.com/v7.0/search and the key back to yours, or choose another engine in the menu. To stop the key working everywhere, revoke it in Agents & API. Questions: [email protected].
