DataForSEO SERP API compatible

The call, before and after

# Before
curl https://api.dataforseo.com/v3/serp/google/organic/live/regular \
  -u "$DATAFORSEO_LOGIN:$DATAFORSEO_PASSWORD" -H "Content-Type: application/json" \
  -d '[{"keyword": "web scraping api", "location_code": 2840, "language_code": "en"}]'

# After
curl https://api.specstream.ai/dataforseo/v3/serp/google/organic/live/regular \
  -u "login:$SPECSTREAM_API_KEY" -H "Content-Type: application/json" \
  -d '[{"keyword": "web scraping api", "location_code": 2840, "language_code": "en"}]'

With DataForSEO's Python client, dataforseo-client 2.1.11, the change is the configuration: Configuration(username="any", password=SPECSTREAM_KEY, host="https://api.specstream.ai/dataforseo"). Your SERP calls then run as before.

What the route reads, and what it refuses

Read and applied: keyword, location_code or location_name, language_code or language_name, depth up to 200, target, tag, se_domain, on both the regular and the advanced form.

Refused, in DataForSEO's own codes: two tasks in one call get 40000, depth over 200 gets the task's 40501, and a wrong 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 version, status_code, status_message, time, cost, tasks_count, tasks_error and tasks[], each task with id, status_code, cost, result_count, path, data and result[]. Each result carries keyword, type, se_domain, location_code, language_code, check_url, datetime, item_types, se_results_count, pages_count, items_count and items[].

Every organic item carries type, rank_group, rank_absolute, page, position, domain, title, description, url, breadcrumb, website_name and the is_* flags. These are present and empty: spell, refinement_chips, and an item's xpath, pre_snippet, extended_snippet, images, rating, price, highlighted, links, faq, extended_people_also_search, about_this_result, related_search_url, timestamp and rectangle.

Pay per task, with no minimum

On DataForSEO the first top-up is at least $50. On SpecStream a new account starts with $10 of credit and no card, each task of up to 10 results costs $0.005, each started block of 10 more adds $0.006, and the cost field shows the price of each call. A busy call gets DataForSEO's own 40202 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. The full comparison is on the DataForSEO alternative page.
