DeFi TVL Rankings

Top DeFi protocols ranked by total value locked (DefiLlama), with 1d/7d change — CEX/Chain/Bridge excluded so this is real DeFi. Pass chain= (e.g. base) to filter to protocols active on it, category= (e.g. Lending, Dexes) to narrow, limit= up to 50. tvlUsd is the protocol's GLOBAL TVL; chain filters presence, not per-chain TVL. The DeFi-rankings commodity, served cheap. Not financial advice.

Provider

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Live 402 challenge

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Show the prompt
Using Roundhouse, look up the x402 service DeFi TVL Rankings and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=DeFi%20TVL%20Rankings'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://402.com.tr/api/x402/defi-tvl, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
