Jina DeepSearch alternative in 2026

The price is fixed before the run

A DeepSearch run spends tokens on every search, page read and reasoning round, and Jina's page says the more steps it takes, the more tokens it uses. You learn the count when the stream ends. budget_tokens sets a maximum, and when the budget runs out first Jina returns the answer it has, which may not have passed its own quality checks.

A SpecStream report costs $0.10, $0.30 or $1.00 by depth. The reply to the POST shows it as price_usd, so a product that resells research can price its own plan per report. The price is taken once, at delivery.

A written report with the passage behind each sentence

DeepSearch answers in chat form and lists the URLs it visited. SpecStream writes a report: report.content carries a [1] marker after each cited sentence, report.citations gives that sentence the URL of its page, the time SpecStream read it and the passage that supports it, and report.sources lists every page read in the run. A reviewer opens the page and finds the passage in seconds.

No connection to hold open

DeepSearch runs inside one request, and Jina strongly recommends streaming because the request can take a long time. POST /v1/research answers 202 at once. Your code reads GET /v1/research/{id} until status is completed, follows the server-sent events, or gets a call on its webhook. An Idempotency-Key header makes a retry return the same report, so a dropped connection never buys a second one.

Your Reader and Search calls keep their code

Teams that use DeepSearch often call r.jina.ai and s.jina.ai too. Set the address to https://api.specstream.ai/jina-search and a search answers in Jina's shape for $1 per 1,000 searches of up to 10 results. Set it to https://api.specstream.ai/jina and a page read costs $0.80 per 1,000 pages, with no charge for a page with no text. The same key runs the Search API, which scores 97.9 F-score on all 1,000 SimpleQA Verified questions. The benchmarks page shows each run. See research reports and Jina Reader pricing.

Linkup Research

SpecStream writes a report for $0.10 to $1.00. Linkup Research costs $0.25, $0.50, $1.50 or $2.50 a request by reasoningDepth. A SpecStream standard report costs $0.30, under Linkup's M depth at $0.50.

Parallel Task API

Parallel prices Task runs per 1,000 by processor: pro at $100 and ultra at $300. A SpecStream quick report costs the same $0.10 as a pro run, and a deep report at $1.00 comes with the passage behind each cited sentence.

Tavily Research

Tavily Research bills 4 to 110 credits a request on mini and 15 to 250 on pro, at $0.008 a credit pay as you go. That is $0.032 to $0.88 on mini and $0.12 to $2.00 on pro, known after the run. A SpecStream report has one price per depth, shown as price_usd when the report starts.
