SpecStream and serpstack side by side
| SpecStream | serpstack | |
|---|---|---|
| What you change | One line. https://api.specstream.ai/serpstack/search in place of https://api.serpstack.com/search, and a SpecStream key as access_key in the address.

Signals such as funding rounds, new executives and layoffs at specstream.ai/signals | Search engine 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 |

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 serpstack to SpecStream
Your serpstack call, answered at a new address
SpecStream answers GET /search in serpstack's own JSON at https://api.specstream.ai/serpstack. Only the address and the key change, so the parser that reads organic_results today keeps working.
curl -G "https://api.specstream.ai/serpstack/search" \
-d "access_key=$SPECSTREAM_API_KEY" -d num=10 --data-urlencode "query=Nvidia earnings"query, num, page, period (last_hour to last_year, or custom with period_start and period_end), gl, hl, safe and type=news keep their meaning. serpstack's own examples are plain HTTP calls, so there is no SDK setting to find.
$5 per 1,000 searches with no plan to outgrow
On serpstack Basic, $29.99 buys 5,000 searches for the month, and the next 1,000 cost $23.99. On SpecStream $29.99 pays for 5,998 searches that never expire, and the 6,000th costs the same $0.005 as the first. A call stopped by a 429 charges nothing.
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.
About one second a search, with no limit per key
Every drop-in 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. There is no limit per key and no daily limit; a busy call 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, and its answer is not reused for another call. spend_cap_cents is the most the key can spend.
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 serpstack 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 serpstack
Change one line. https://api.specstream.ai/serpstack/search answers the call your code sends to https://api.serpstack.com/search today, in the same JSON, so your parser stays as it is. Send a SpecStream key as access_key. A new account gets $10 of credit, no card, which covers 2,000 searches.
# Before
curl -G "https://api.serpstack.com/search" -d "access_key=$SERPSTACK_KEY" --data-urlencode "query=$QUERY"
# After
curl -G "https://api.specstream.ai/serpstack/search" -d "access_key=$SPECSTREAM_API_KEY" --data-urlencode "query=$QUERY"Each result keeps position, title, url, domain, displayed_url and snippet, and pagination.next_page_url leads to the next page. A call of up to 10 results is one search at $0.005. Every parameter and reply field is in the serpstack migration guide. The steps:
1. Create a key under Agents & API in the workspace, and set a spending limit on it.
2. Point the address at https://api.specstream.ai/serpstack/search. In Python:
import requests
reply = requests.get(
"https://api.specstream.ai/serpstack/search", # was https://api.serpstack.com/search
params={"access_key": SPECSTREAM_KEY, "query": "Nvidia earnings", "num": 10},
timeout=30,
)
reply.raise_for_status()
for result in reply.json()["organic_results"]:
print(result["position"], result["title"], result["url"])3. In JavaScript, a news search:
const url = new URL("https://api.specstream.ai/serpstack/search");
url.search = new URLSearchParams({ access_key: process.env.SPECSTREAM_KEY, query: "Nvidia earnings", type: "news", sort: "date" });
const data = await (await fetch(url)).json();
for (const item of data.news_results) console.log(item.uploaded_utc, item.source_name, item.title, item.url);4. Follow pagination.next_page_url for the next page, and read 429 as a call to send again after Retry-After. It is not charged.
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.
