Deep Research (u14app)

Run u14app's Deep Research on SpecStream's search: set SEARXNG_API_BASE_URL on the server to https://api.specstream.ai/searxng/YOUR_SPECSTREAM_KEY and choose SearXNG as the search provider. The web app in Proxy mode, the SSE API and the MCP server then search the live web through SpecStream at $1 per 1,000 searches.

SpecStream for Deep Research (u14app)Agent frameworks & builders

What you need

  1. 1. Make a SpecStream key

    In SpecStream, open Agents & API, choose API keys, then Create API key. Turn on Authorize paid work and give the key a Total spending limit. The key is shown once.

  2. 2. Set the address on the server

    Deep Research reads the SearXNG address from SEARXNG_API_BASE_URL, and falls back to http://0.0.0.0:8080 without it. Add these lines to .env (or .env.local while you develop), with your key in place of YOUR_SPECSTREAM_KEY. With Docker, pass the same two variables to the container.

    Deep Research adds /search and format=json itself, so the address ends at your key. MCP_SEARCH_PROVIDER makes SearXNG the search of the MCP server too. Redeploy so the server reads the new values.

    .env
    SEARXNG_API_BASE_URL=https://api.specstream.ai/searxng/YOUR_SPECSTREAM_KEY
    MCP_SEARCH_PROVIDER=searxng

  3. 3. Choose SearXNG in the web app

    Open Setting and set API Mode to Proxy. In Proxy mode the browser sends each search to your server, and the server forwards it to the address you set, so the key never reaches the browser.

    If the server has ACCESS_PASSWORD, type the same password in Access Password. Turn on Web Search, choose SearXNG under Search Provider, and click Save.

  4. 4. Use it from the SSE API and the MCP server

    A call to /api/sse with searchProvider set to searxng searches through the same server address.

    The MCP server answers at /api/mcp (Streamable HTTP) and /api/mcp/sse (SSE), and takes its search from MCP_SEARCH_PROVIDER, set in step 2. When the server has ACCESS_PASSWORD, the MCP server asks for it too.

  5. 5. Check it works

    Start a short research task with Web Search on. Each search is in your SpecStream request log with the SearXNG route as its endpoint and its price: GET https://api.specstream.ai/v1/account/requests lists them, newest first.

What each search costs

Each search Deep Research sends to the SearXNG address is one Search API call on the fast tier: $1 per 1,000 searches of up to 10 results, a fifth of the default search's $5. A SearXNG call names no result count, so each one gets one page of 10 results at that price, and a search that returns nothing costs nothing. A research task runs several searches, one for each query the model plans.

Searches come out of your balance with no quote and no approval. New accounts start with $10 of credit, no card. Questions go to [email protected].

Limits and errors

  • When search is busy, SpecStream answers 429 with a Retry-After header and charges nothing.
  • A key SpecStream does not accept answers 401. Check the key in SEARXNG_API_BASE_URL, and that it can search.
  • A key over its spending limit answers 403. Raise the limit under API keys in Agents & API.

Keep the key private

The key is part of the address, so keep .env and .env.local out of git and set the variable as a secret on your host. To end a key's access, revoke it under API keys in Agents & API and make a new one.

Read pages and get rows too

The same key reads pages with the Extract API at $0.80 per 1,000 pages, and a page with no text is not charged. For a dataset, add SpecStream's MCP server at https://api.specstream.ai/mcp and ask for the records in plain words. Deep Search returns every match as structured rows at 5¢, 15¢ or $1 a row, under a maximum you approve. See MCP and deep research APIs.

Go back

Remove SEARXNG_API_BASE_URL, choose another search provider in Setting, and redeploy. Then revoke the key in your workspace if you no longer use it.
