api record

Web3Juice is research data on about 17,000 DeFi yield pools (lending, vaults, liquidity and staking on 100+ chains), refreshed about every 15 minutes. Start with summarize_yields for market questions ("what does USDC lending pay?") or search_pools to find pools; pass returned pool ids unchanged to get_pool, get_pool_history or compare_pools. In tool arguments and structured data, rates are fractions (0.05 = 5%); text summaries show percentages. Unknown means unknown, never zero. Source measurement time and Web3Juice retrieval time are different. This is data, not financial advice: do not tell…

_ is it live, free and safe measured by this hub
Is web3juice live?
Yes — it answered the hub's last check (checked 47m ago). It answered 100% of checks over the last 30 days.
Is web3juice free to use?
Yes — the hub reached it with no key and no payment.
What tools does web3juice have?
7 tools: get_pool, get_pool_history, compare_pools, get_methodology, summarize_yields, search_pools, get_data_sources.
Is web3juice safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • summarize_yields open 47m ago

    Market overview for any filter: number of pools, total TVL, median, middle-half and TVL-weighted APY, grouped by chain (default), protocol or strategy, with the largest pool in each group. Rates in filters are fractions (0.05 = 5%).

  • search_pools open 47m ago

    Find DeFi yield pools (lending, vaults, liquidity, staking) by token, chain, protocol, APY and TVL. Returns a ranked table with pool ids. Rates are fractions (0.05 = 5%). Defaults: 10 rows, largest TVL first, pools with at least $100,000 TVL, data under 60 minutes old. Stablecoin filters check token labels, not peg safety. Page with the returned cursor.

  • get_pool unknown never probed

    Full detail for one pool id: APY split into base and reward-token yield, TVL, when the source measured it and when Web3Juice retrieved it, contract and token addresses, deposit and source links, withdrawal evidence and the experimental assessment. Links and labels come from the source and are unverified.

  • get_pool_history unknown never probed

    APY trend for one pool over 7, 30 (default) or 90 days: median, low, high, latest and the dated samples. Uses saved data only (the provider history cache, else Web3Juice snapshots); nothing is fetched. No history means unknown, not zero.

  • get_methodology unknown never probed

    How the experimental evidence assessment works: dimensions, weights, caps and why most pools show "not scored". A score is not a safety guarantee.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id f3549a831089153b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f3549a831089153b/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/f3549a831089153b/badge.svg)](https://brick.blue/agent/f3549a831089153b?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
