Pay only for what you use. Transparent pricing with no hidden fees. Start free, then add a plan whenever you want premium sources at a lower cost per credit.

​
Plans

Everything runs on credits. $1 = 1 credit, and a single credit balance is shared across every API - Search, Answer, Contents, and DeepResearch. Higher plans simply give you more credits per dollar and unlock specialised and proprietary data sources.
Start free. New accounts get $10 in free credits ($20 with a work email), usable across every source so you can try the full catalog first. New organisations also get 50% off their first month for the first 24 hours after signup.

Per-retrieval pricing (CPM)

Search and Answer price on CPM - cost per thousand retrievals. Set max_price to cap spend per query (sources priced above the cap are excluded, and the response returns a 206 partial-success warning). If you don’t set it, Valyu returns the best results regardless of source cost.
Data source typePer 1k retrievalsWhat you get
Open databases$0.50Full-text arXiv, Wikipedia, PubMed, and more
Web search$1.50Fresh, full-text web content
Financial & market data$8.00Real-time equities, crypto, market data
Proprietary databases$30-50Licensed journals, books, premium sources
Contents API charges $0.001 per successfully extracted URL, plus $0.001 if you add summarisation or structured extraction. Failed URLs are free. Answer API bills search data (CPM rates above, capped by data_max_price) plus $12 per million tokens for AI processing.
Contents - 10 URLs, 2 failed: 8 × $0.001 = $0.008.Answer - basic web query: ~10 results × $1.50/1k ($0.015) + ~2k tokens × $12/1M ($0.024) = ~$0.039.Answer - academic with structured output: ~8 results × $8/1k ($0.064) + ~3k tokens × $12/1M ($0.036) = ~$0.10.

​
DeepResearch pricing

Fixed price per task - no extra search or content charges. DeepResearch plans, searches, verifies, and writes a cited report.
ModeCostTypical runtime
Fast$0.10~5 min
Standard$0.50~10-20 min
Heavy$2.50up to ~90 min
Max$15.00up to ~180 min
Optional tools (off by default, enabled via tools) add per-use surcharges: screenshots $0.05/URL (max 15), code execution $0.10/run, deliverables $0.10 each after the first, charts free. Failed tool calls aren’t charged, and PDF output isn’t a deliverable.
Every completed task returns the total and an itemized breakdown. Surcharge fields are omitted when 0.
