The serpstack reference, on SpecStream
The call, before and after
# Before
curl "https://api.serpstack.com/search?access_key=$SERPSTACK_KEY&query=mcdonalds"
# After
curl "https://api.specstream.ai/serpstack/search?access_key=$SPECSTREAM_API_KEY&query=mcdonalds"serpstack's own Python example is a plain requests.get call, so the change is the address and the key in that one line: requests.get("https://api.specstream.ai/serpstack/search", {"access_key": SPECSTREAM_KEY, "query": "mcdonalds"}).
What the route reads, and what it refuses
Read and applied: query, num, page, period (last_hour, last_day, last_week, last_month, last_year, or custom with period_start and period_end as YYYY-MM-DD), gl, hl, safe, type=news, sort=date on news, and pagination.next_page_url for the next page.
Refused, in serpstack's own error body: type=images gets 400 with code 314, engine=bing gets 311, an unknown period gets 316, and a call with no access_key gets 401. Every parameter was measured on production on Nov 10, 2026, and the full pass table lists each one and its result.
Every field that comes back
The reply has request with success, processed_timestamp and total_time_taken, search_parameters with engine, query, type, page and num, search_information with total_results, time_taken_displayed, query_displayed and no_results_for_original_query, organic_results[] or news_results[], and pagination with current_page, next_page_url and other_page_urls.
The route does not return request.search_url, search_parameters device, google_domain, hl and gl, did_you_mean, showing_results_for, detected_location, a news item's thumbnail_url, nor ads, answer_box, knowledge_graph, local_results, related_questions, related_searches, inline_images and top_stories.
One price a search, and no overage
On serpstack Basic each search over the 5,000 in the plan costs $0.023992. On SpecStream every call of up to 10 results costs $0.005, each started block of 10 more adds $0.006, and there is no plan to renew. A busy call gets 429 with Retry-After and charges nothing. Credit you buy never expires.
The most accurate web search API, in about one second
On SimpleQA Verified the SpecStream Search API scores 97.9 F-score on all 1,000 official questions, 978 of them correct. On WideSearch it scores 64.0 item F1 and 43.4 row F1 on all 200 official tasks. The Extract API scores 0.908 F1 on WCXB. Every score and its method is on the benchmarks page.
Every drop-in route runs the fast search. Measured on production on November 9, 2026, its median was 0.82 s at 1 search a second and 1.07 s at 20 a second, the 95th percentile stayed between 1.09 and 1.73 s, and it answered 718 of 720. There is no limit per key and no daily limit.
You decide what is kept, on each key
Create the key with zero_retention and a search made with it keeps no request text and no answer after the reply. 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
The same key reads up to 20 pages or documents a call with the Extract API at $0.80 per 1,000 pages, and a page with no text is not charged. Deep Search returns every match for a request in plain words as structured rows, at 5¢, 15¢ or $1 a row, with a source URL on every value.

How to migrate, step by step
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. Set the address to https://api.specstream.ai/serpstack/search where your code has https://api.serpstack.com/search, and send the SpecStream key as access_key. In Python:
import requests
URL = "https://api.specstream.ai/serpstack/search" # was https://api.serpstack.com/search
reply = requests.get(URL, {"access_key": SPECSTREAM_KEY, "query": "mcdonalds", "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:
const url = new URL("https://api.specstream.ai/serpstack/search");
url.search = new URLSearchParams({ access_key: process.env.SPECSTREAM_KEY, query: "mcdonalds" });
const data = await (await fetch(url)).json();
for (const result of data.organic_results) console.log(result.title, result.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.
