Search in plain words
Press ⌘K and type what you mean, such as “eth 2000 call” or “btc 24 sep”, to jump straight there.

FAQ
Frequently asked questions.
Short answers to what people ask most.
What is Weilo?
Weilo is a free, live analytics terminal for on-chain options and perpetuals. It shows market-wide volume, the trade tape, a wallet leaderboard, options flow by expiry, and a profile for every instrument and wallet.
Is Weilo free to use?
Yes. The terminal is public: there is no account, no wallet connection and no paywall.
Which markets does Weilo cover?
Options and perpetual futures on Derive, across every listed asset. You can filter by asset and instrument type, or look at the whole market at once.
How is volume counted?
Volume counts the taker side once per trade, so a single fill is never double-counted. The wallet leaderboard is the exception: it credits both sides, so makers and takers both rank.
How fresh is the data?
The data refreshes every 15 minutes, and every view shows when it was last updated.
Can I share what I am looking at?
Yes. Asset, period and instrument filters are part of the URL, so copying the address shares the exact view.
Can AI agents use Weilo?
Yes. Give your agent the link weilo.xyz/skill.md: it explains the public JSON API, what every field means and how to link to any view. Agents browsing the site also find it through /llms.txt.
Is Weilo financial advice?
No. Weilo is for research and educational purposes only. It does not recommend trades, and nothing on the site is financial advice.
