list_rwa_yieldsread-onlyLists tokenized real-world asset deployments (tokenized US treasuries, credit, funds) with current APY and TVL, from public DefiLlama data. Filter by chain or kind. Information only, not advice.
get_rwa_assetread-onlyReturns every deployment of one tokenized asset symbol (e.g. BUIDL, USDY, OUSG) across chains, with total TVL and curated description.
rwa_market_summaryread-onlyTotals for the tokenized treasury market: distinct tokens, total TVL, median APY, top tokens by TVL, plus totals for other tokenized real-world assets.
compare_yield_to_tokenized_treasuriesread-onlyGiven an APY the user currently earns (e.g. a bank savings rate), computes the simple-interest difference versus the highest-yielding liquid tokenized treasury over a horizon. Returns arithmetic and assumptions only; it does not recommend.
list_stablecoin_yieldsread-onlyWhere USDC, USDT, DAI, USDe and other stablecoins earn yield right now: single-asset pools on lending markets and vaults (credit and basis venues on Pro) (DefiLlama data, excludes tokenized treasuries, which have their own tools). Each row carries its protocol category group (lending, vault, credit, basis), base vs reward APY, 30-day mean APY and TVL. Default: pools with at least $10M TVL, highest
stablecoin_yield_summaryread-onlyPer stablecoin: venues, total TVL, median APY, best venue overall and best collateralized-lending venue; totals by category group; and the median tokenized treasury APY for comparison. Pools with at least $10M TVL by default.
list_tokenized_equitiesread-onlyTokenized equities on public chains (xStocks, bStocks, Ondo Global Markets, Robinhood, Dinari, Coinbase and others): token price, market cap, 24h volume, the underlying ticker, chains, and (on Pro) premium or discount to the latest underlying quote. Filter by issuer, kind (stock, pre-ipo, etf), underlying or chain. Information only, not advice.
get_tokenized_equityread-onlyAll tokenized versions of one underlying stock (e.g. TSLA) across issuers: market caps, volumes, chains, the most liquid wrapper, and (on Pro) the premium/discount range versus the underlying quote.
tokenized_equity_summaryread-onlyTotals for tokenized equities: token count, market cap and 24h volume; breakdown by issuer and by kind; top underlyings by combined market cap (top 5 on Free, 10 on Pro); on Pro, how many tokens have an underlying quote and the median absolute premium.
rwa_issuer_termsread-onlyHand-curated terms for a tokenized treasury token: who may invest (US persons?), minimum, structure (summary on Free; Pro adds what backs it, domicile, redemption method and timing, fees, yield mechanics and source URLs). Covers BUIDL, USYC, USDY, OUSG, USTB, TBILL, STBT, BENJI. Null means not stated by the source.
rwa_historyread-onlyDaily snapshots of total TVL and TVL-weighted APY for one symbol, optionally on one chain, over the last N days (default 30; Free and anonymous plans see 7, Pro the full history). universe "rwa" (tokenized assets, default) or "stablecoin" (stablecoin pools). Includes the change from first to last day.
rwa_changesread-onlyCompares the latest market with the snapshot from N days ago (default 1): APY and TVL change per deployment, biggest movers first, plus new and vanished deployments. universe "rwa" (default) or "stablecoin".
create_alertCreates a rule that is checked every hour after the data refresh. When any matching deployment crosses the threshold, YieldCave POSTs a JSON payload to your HTTPS webhook (Slack, Discord, Zapier, your own server). Fires at most once per 24 hours per rule. universe "rwa" (tokenized treasuries, default) or "stablecoin" (stablecoin pools with at least $10M TVL; omit symbol for all major stablecoins).
list_alertsread-onlyLists active alert rules (webhook hosts only, never full URLs).
delete_alertcan modifyDeletes an alert by id.
create_api_keyCreates a free YieldCave API key (300 calls/day, 3 alerts, 7 days of history) tied to an email address. The key is shown once. Send it on every request as an x-api-key header or Authorization: Bearer. One key per email.
my_usageread-onlyShows the caller's plan, calls used today, remaining allowance, alert allowance, depth limits, and what each plan includes.
