Loading your visibility preference…
Sends your question to scholarly repositories. DOI lookup works when a DOI is in the question. Public papers cost no source USDC; unavailable papers and abstract-only reads stay visible.
Requires your authenticated funded browser session. Each live review expires after 60 seconds. Agreement admits this read within your existing cap; it does not sign a payment.
Look up free paper metadataResearch may search the public web; your question is sent to our search provider. The USDC source budget is separate from model and search operating costs.
How Keryx researches a question
Keryx compares source previews and prices under your cap, then explains what it reads or skips. Unused browser-session funds remain yours; prepaid reserves follow the package terms.
It reads available public or purchased material and writes an answer with citations to supporting sources. Unavailable content and thin evidence remain visible.
Eligible cited creators receive weighted USDC rewards on Arc mainnet. The answer and public ledger distinguish settled, pending, and simulated payments.
Inspect the evidence
Trust comes from what you can check.
Open source decisions and original references. Payment records distinguish settled, pending, failed and simulated states. A saved answer or a registry entry alone does not prove a payment or a useful result.

How to verify AI citations: a practical checklist
Check whether an AI citation exists, matches the claimed paper and supports the specific claim. A practical workflow for DOI checks, source passages and corrections.
Your words are the answer. Be paid like it.
Add an RSS feed you control, choose its access toll, and prove ownership. Keryx can pay for a read when it buys an article, then send a separate weighted reward if that article supports a cited answer. See each payment and its state in the public ledger. Payments use Arc mainnet USDC.
Before your first question
Do I need a wallet to try Keryx?
The sponsored public trial needs no wallet or USDC deposit. Keryx covers approved source spending and operating costs within its usage and spending limits. The form shows a notice when the trial is paused.
Can I submit confidential research?
Sponsored trial reports have public links. Use questions you can share publicly. Review the separate private-research flow and privacy terms before submitting confidential material; signing in alone does not make a trial report private.
Does every citation pay a publisher?
No. Public pages can be read without a source access toll. Creator rewards require qualifying evidence and verified payout authority. Sponsored operating fees, when eligible, are recorded separately and are not publisher payments.
Are demo reports or AI answers verified facts?
No. Synthetic examples are demonstrations, and historical testnet receipts stay labelled as testnet. AI answers can be incomplete or wrong: inspect the original sources, evidence limitations and payment state before relying on a report.
