SpecStream and Zenserp side by side
| SpecStream | Zenserp | |
|---|---|---|
| What you change | One line. https://api.specstream.ai/zenserp/api/v2/search in place of https://app.zenserp.com/api/v2/search, and a SpecStream key in the apikey header. The request and the reply keep their shape | GET /search with a Zenserp key in the apikey header |
| What a call returns | GET /v1/web-search returns an answer with the value, the page it was read on and the time it was read, rows with the facts the request asks for, and sources in rank order with url, title, snippet and the published date when the result gives one | Google results as JSON from one /search endpoint at https://app.zenserp.com/api/v2/search: organic results, ads and featured snippets |
| Price per month | $5 for up to 10 results, the same rate on every plan. num=100 costs $0.059 a call | Small $49.99 for 25,000 searches, Medium $149.99 for 100,000, Large $299.99 for 250,000, Premium $499.99 for 500,000, Enterprise $899.99 for 1,000,000 |
| An answer to the question | answer is in the reply of a $0.005 search: the value, the page it was read on and the time it was read | An AI Overview request uses 3 searches |
| When the searches run out | Calls spend from your balance, inside the spending limit you set on the key. A top-up never expires | Email alerts at 90% and 100% of the plan's usage |
| Volume | The fast search takes up to 8,800 searches a minute on one account. A call over that gets a 429 with Retry-After and is not charged | The Batch Endpoint and a Custom Queue on the higher plans |
| Failed calls | A 429 with Retry-After charges nothing. With an Idempotency-Key, a retried call is charged once | Only successful requests are billed |
| Free to start | $10 of credit, no card. That is 2,000 searches, or up to 200 rows at 5¢ | Free plan: 50 searches a month |
| What answers the call | The whole live web, read at the moment of the call. 97.9 F-score on all 1,000 SimpleQA Verified questions (978 correct) and 64.0 item F1 on all 200 WideSearch tasks | Google and the other engines Zenserp reads, such as Bing |
| The text of the pages | Add passages=true and each source carries an excerpt of its page, up to about 3,500 characters. The Extract API returns the main text of up to 20 pages or documents (PDF, Word, Excel) a call, at $0.80 per 1,000 pages | The snippets of the results page |
| Data already held | Public databases read every morning at specstream.ai/data: every company that filed a Form D since 2023 with its filing history, nearly 2 million US nonprofits, every US bank failure since 1934, federal rules, open federal contracts and grants, and local businesses. Signals such as funding rounds, new executives and layoffs at specstream.ai/signals | Results pages fetched one query at a time |
| Every match as structured rows | Deep Search: a request in plain words returns every match on the live web as rows that meet each condition you wrote, at 5¢, 15¢ or $1 a row, plus 5¢ for an email and 15¢ for a phone. The most a run can cost is quoted before it starts, and nothing runs until you approve it | One results page per call |
| Reruns and change labels | Hourly to yearly. Each row comes back labeled changed, unchanged or no longer matching. A changed or new row costs half its rate, an unchanged row 1¢ | Each call is a new search, counted against the month's plan |
| Where the data goes | Google Sheets, Excel, Airtable, Notion, monday.com, HubSpot, Salesforce, Pipedrive, Attio, Slack, Teams, Zapier, Make, n8n and signed webhooks. Agents use the MCP server, the REST API, the Python and TypeScript SDKs, a CLI and A2A | A JSON response to the code that called the API |
Why teams move from Zenserp to SpecStream
One call returns the answer and its sources
A Zenserp call returns the results page, and Google's AI Overview costs 3 searches more. A SpecStream call takes the question in everyday words and returns the value with the page it was read on, the rows the question asks for, and every source in rank order, all for $0.005.
curl "https://api.specstream.ai/v1/web-search?q=Who+is+the+CEO+of+Mistral+AI&num=10" \
-H "Authorization: Bearer $SPECSTREAM_API_KEY"When your product reads a results list, POST https://api.specstream.ai/serper/search returns organic[] with position, title, link and snippet, at the same $0.005 a search.
The most accurate web search API in the world
The SpecStream Search API scores a 97.9 F-score on all 1,000 official SimpleQA Verified questions, with 978 correct. On WideSearch it scores 64.0 item F1 and 43.4 row F1 on all 200 official tasks, and the Extract API scores 0.908 F1 on WCXB. The scores and the method are at specstream.ai/benchmarks.
$5 per 1,000 searches from a balance that does not expire
Zenserp's Small plan is $49.99 a month for 25,000 searches, and the searches belong to that month. SpecStream charges $0.005 a search on every plan, from a balance that never expires, so a quiet month costs nothing. A call stopped by a 429 charges nothing, and the most a key can spend is the limit you set on it.
About one second a search, at up to 8,800 a minute
Every results list route runs the fast search unless the call asks for page text or results past the first ten. On November 9, 2026 production took 1 to 20 fast searches a second and answered 718 of 720: the median was 0.82 s at 1 search a second and 1.07 s at 20 a second, and the 95th percentile stayed between 1.09 and 1.73 s. One account takes up to 8,800 searches a minute, and a call over that gets a 429 with Retry-After and is not charged.
Zero retention on any key
Set zero_retention when you create a key, or later. A search made with that key keeps no request text and no answer after the reply: it is not in the history, its answer is not reused for another call, and its log lines carry neither. The charge keeps the account, the key, the request ID, the price and the time.
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
A product that calls Zenserp still has to read the pages and build its own records. On SpecStream the same key reads up to 20 pages or documents a call with the Extract API at $0.80 per 1,000 pages, and runs Deep Search, which returns every match on the live web as structured rows at 5¢, 15¢ or $1 a row. 10,000 rows with 5 facts each cost $500, and the most a run can cost is approved before it starts. Save a request and it reruns hourly to yearly, with each row labeled changed, unchanged or no longer matching.

How to switch from Zenserp
Change one line. https://api.specstream.ai/zenserp/api/v2/search answers the call your code sends to https://app.zenserp.com/api/v2/search today, in the same JSON, so your parser stays as it is. Send a SpecStream key in the apikey header. A new account gets $10 of credit, no card, which covers 2,000 searches.
# Before
curl "https://app.zenserp.com/api/v2/search?q=$QUERY" -H "apikey: $VENDOR_API_KEY"
# After
curl "https://api.specstream.ai/zenserp/api/v2/search?q=$QUERY" -H "apikey: $SPECSTREAM_API_KEY"q, num, start, timeframe, tbs, ai_overview and search_engine work as before, and the reply keeps organic[] with position, title, url, destination and description. A call of up to 10 results is one search at $0.005. Every parameter and reply field is in the Zenserp migration guide.
Your code can also call SpecStream's own Search API, at the same price. The steps:
1. Create a key under Agents & API in the workspace. A new account gets $10 of credit, no card, which covers 2,000 searches.
2. Send the question to GET https://api.specstream.ai/v1/web-search with the key as a Bearer token, where your code calls https://app.zenserp.com/api/v2/search with apikey today. num sets the results from 1 to 100.
import requests
reply = requests.get(
"https://api.specstream.ai/v1/web-search",
params={"q": "Who is the CEO of Mistral AI", "num": 10},
headers={"Authorization": f"Bearer {SPECSTREAM_KEY}"},
).json()["data"]
print(reply["answer"])
for source in reply["sources"]:
print(source["url"], source["title"], source["snippet"])3. Where your code reads the organic results, read sources (each with url, title and snippet), or call POST https://api.specstream.ai/serper/search and read organic[], whose items carry position, title, link and snippet.
import requests
reply = requests.post(
"https://api.specstream.ai/serper/search",
headers={"X-API-KEY": SPECSTREAM_KEY},
json={"q": "Who is the CEO of Mistral AI", "num": 10, "page": 1},
).json()
for result in reply["organic"]:
print(result["position"], result["title"], result["link"], result["snippet"])4. Set a spending limit on the key. A call of up to 10 results costs $0.005, and num=100 costs $0.059.
When your product needs the whole dataset in place of a results page, write the request in plain words. SpecStream reads it back as the conditions every row must meet and the facts to bring back, quotes the most it can cost, and delivers the rows after you approve.
