Measured tools (6)

• health read-only

  Liveness and capability check for yieldhunter (yieldhunter.eth). Returns service status, schemaVersion, scoringVersion, feature flags, and the list of available tools. Use this first to verify connectivity. If yields+pegs vintage is missing or at/over YH_STALE_DEGRADE_SECONDS (default 2h), health may refresh DefiLlama market caches once (same adapters as list_yields; not a list_yields tool call). Kill switch on: health still answers, refresh skipped. Research estimates only — non-custodial; never holds keys or executes transactions. Copy-paste path starts here, then list_yields. Example input: {}

• list_yields read-only

  Rank stablecoin yield opportunities on Ethereum, Base, and Arbitrum using multi-factor **risk-adjusted** scoring (not raw APY). chains/chainIds: those three only (aliases eth/ETH/Ethereum, arb/ARB, BASE) — any unsupported or blank value (solana, optimism, "") is VALIDATION_ERROR, not a silent default-universe fallback. sourceChainKey: same keys/aliases; blank or unknown keys are VALIDATION_ERROR (bridge cost is not estimated). Default ranking is risk-adjusted score, not highest APY. For headline yield order, use sortBy=net_apy. Default is risk-adjusted ranking with balanced weights. Optional params are policy controls for visiting agents. Default when omitted: sortBy=risk_adjusted, sortOrder=desc, riskAppetite=balanced (v1.1 weights), no minScore, no category filter, diversity=soft (max 2 markets per protocol in presented top-k). Primary composite key: compositeRiskAdjusted (protocol risk, depeg/counterparty, liquidity, yield quality base vs incentive, net yield after gas/bridge). Opportunities may include stability signals: apyChange24h is pool-level DefiLlama apyPct1D when present as a number (including 0 = observed flat change); null/missing means unknown/not provided for that pool (e.g. some Pendle markets) — not the same as 0, never invent 0; tvlChange24hPct is protocol-level DefiLlama change_1d (shared across markets of the same protocol — not this pool's TVL flow; missing stays null); large APY jumps warn only. Also exitRisk/exitRiskReason (size-vs-pool liquidity heuristic only: pool TVL vs notionalUsd + liquidity confidence — not on-chain withdraw, not queue/cap/pause/lockup, not transfer whitelist/eligibility/redemption, not an execution gate; unknown ≠ safe; medium often means liquidity confidence medium, not “small pool”; low is strict; when knownIssues mention transfer/eligibility do not treat low as free exit; soft warnings on high/unknown, plus low/medium if those issues are present; does not change default risk-adjusted ranking). Optional policy knobs: sortBy (risk_adjusted|net_apy|gross_apy|tvl), sortOrder, riskAppetite (conservative|balanced|aggressive), minScore (0–100 after appetite; practical bands ~≥85 treasury default, ≥80 selective; 90 is rare/very strict — a few top L2 blue-chips may clear it), categories / excludeCategories (lending|rwa|other), diversity (soft|off — default top prefers protocol diversity; set off for every market from one protocol), includeFactors (boolean, default false — when true each opportunity has scores.factors compact map without a second tool call), maxRewardShare (0–1 optional incentive-share gate only — max reward/total; e.g. 0.3 treasury, 0.25 stricter; unknown share excluded when set; does not remove high base-only APY farms — pair with minScore/riskAppetite/excludeCategories for capital preservation). Prefer this when capital preservation and sustainable yield matter more than headline APY. Research only — never executes transactions or holds keys. Copy-paste path (after health {}): { "assets": ["USDC"], "sortBy": "risk_adjusted" } Then contrast #1 vs #2 (risk-adjusted winner vs next row — often higher rate / thinner liquidity / other chain). Do not contrast against the max-APY row in the ten. Examples: (a) Treasury/conservative: { "riskAppetite": "conservative", "minScore": 85, "excludeCategories": ["rwa"], "maxRewardShare": 0.3, "minTvlUsd": 10000000, "limit": 10 } (b) Default research (v1.1): { "assets": ["USDC"], "sortBy": "risk_adjusted" } (c) Yield-seeking: { "sortBy": "net_apy", "riskAppetite": "aggressive", "chains": ["base"], "assets": ["USDC"], "limit": 15 } (d) With factor breakdown: { "assets": ["USDC"], "limit": 5, "includeFactors": true }

  Parameters:

  • limit — integer — Max results to return (default 10, max 25). Example: 10
  • assets — array — Stablecoin symbols to match in pool symbol, e.g. ["USDC","USDT"]
  • chains — array — Filter chains: ethereum | base | arbitrum (aliases eth/ETH/Ethereum, arb/ARB, BASE; or Llama names). Default when field omitted: all three. Blank, whitespace, or unsupported values (solana, optimism, "") are VALIDATION_ERROR — not a silent fallback. Example: ["base","ethereum"]
  • sortBy — string — Sort key: "risk_adjusted" (default) | "net_apy" | "gross_apy" | "tvl"
  • chainIds — array — Optional numeric chain ids: 1, 8453, 42161 only. Any other id is VALIDATION_ERROR (not a silent default-universe fallback).
  • minScore — Minimum compositeRiskAdjusted after appetite weights (0–100). Omitted = no filter
  • diversity — string — Presented top-k protocol diversity: "soft" (default, max 2 per protocol) | "off" (plain score order, every market)
  • minTvlUsd — number — Minimum TVL in USD (default 1000000). Example: 5000000
  • protocols — array — Optional protocol slugs, e.g. ["aave-v3","morpho-blue"]. Blank entries are VALIDATION_ERROR (not treated as all protocols).
  • sortOrder — string — Sort direction: "desc" (default) | "asc"
  • categories — array — Include only these categories: "lending" | "rwa" | "other"
  • horizonDays — number — Holding horizon in days for gas/bridge amortization (default 30). Example: 30
  • notionalUsd — number — Notional USD size for net-yield cost amortization and exitRisk TVL multiples (default 10000). Example: 10000
  • riskAppetite — string — Scoring weight profile: "balanced" (default/v1.1) | "conservative" | "aggressive"
  • includeFactors — boolean — If true, each opportunity includes scores.factors compact map (protocolRisk, depegCounterparty, liquidity, yieldQuality, costAdjusted). Default false — omits heavy factors[] rationales.
  • maxRewardShare — Incentive-share gate only: max reward/total of gross APY, 0–1 (e.g. 0.3 treasury, 0.25 stricter). Does not remove high base-only APY farms. Capital preservation still needs minScore/riskAppetite/excludeCategories. Omitted = no filter. Unknown share excluded when set.
  • sourceChainKey — string — Agent's current chain for bridge cost estimate: ethereum | base | arbitrum (aliases: eth, ETH, Ethereum, arb, ARB, BASE). Blank/whitespace is VALIDATION_ERROR (omit the field to default). Unknown keys (solana, foo) return VALIDATION_ERROR — no invented bridge fee.
  • excludeCategories — array — Exclude these categories, e.g. ["rwa"]

  Side-by-side comparison of 2–5 opportunities by risk-adjusted score. Pass list_yields opportunities[].id values as poolIds or opportunityIds. Returns ranked list, compact comparison table fields (including protocolSlug for get_protocol_risk), winnerId, and rationale bullets (including when raw APY leader differs from risk-adjusted winner). sourceChainKey is ethereum|base|arbitrum only (unknown → VALIDATION_ERROR; no invented bridge fee). Research only — non-custodial. Example: { "poolIds": ["pool-id-a", "pool-id-b", "pool-id-c"], "horizonDays": 30 }

  Parameters:

• explain_score read-only

  Agent-readable explanation of why an opportunity received its risk-adjusted score. Chain: pass list_yields opportunities[].id as poolId, opportunityId, or id (aliases for the same key). Returns a summary paragraph, factor bullets with weighted contributions, net-yield notes, an exitRisk heuristic line (liquidity-only — not on-chain withdraw or transfer/eligibility; medium often confidence-driven, not pool size; extra bullet when knownIssues note transfer restrictions), plus id and protocolSlug (same as list_yields; pass protocolSlug to get_protocol_risk). sourceChainKey is ethereum|base|arbitrum only (unknown → VALIDATION_ERROR; no invented bridge fee). Prefer this when you need to justify a ranking to a human or another agent. Research only — non-custodial. Example: { "opportunityId": "43641cf5-a92e-416b-bce9-27113d3c0db6", "horizonDays": 30 } Also accepts poolId or id with the same value.

• get_protocol_risk read-only

  Protocol-level risk card (age, audit signals, curated known issues, category, score 0–100). Chain: pass list_yields opportunities[].protocolSlug as protocol or protocolSlug. Display names also resolve case- and space-insensitively via DefiLlama protocol metadata (e.g. "Compound V3" → compound-v3, "Curve" → curve-dex, "Euler V2" → euler-v2). Unknown names return NOT_FOUND naming the field, with example {"protocolSlug":"aave-v3"} and up to 3 closest slugs. Higher score = lower protocol risk. Uses curated priors plus DefiLlama metadata when available. Research only — non-custodial. Example: { "protocol": "aave-v3" } Also accepts protocolSlug or a display name such as "Compound V3".

  Parameters:

  • protocol — string — Protocol slug (DefiLlama project id) or display name, e.g. "aave-v3" or "Compound V3". Prefer list_yields opportunities[].protocolSlug.
  • protocolSlug — string — Alias for protocol — list_yields opportunities[].protocolSlug (display names also resolve).
