get_markets — Market Query

Queries Pendle markets with structured filters, sorting, and pagination. Only safe, whitelisted markets are returned.

Important: By default, only address and chainId are returned. Use the include parameter to request additional fields (e.g. include: ["name", "details_impliedApy"] or include: ["all"] for everything). Hard-capped at 50 rows.

Available Fields

Field	Description
address	Market contract address (default)
chainId	Blockchain chain ID (default)
name	Market display name
symbol	Market symbol
expiry	Maturity date (ISO 8601)
pt	Principal Token address
yt	Yield Token address
sy	Standardized Yield token address
underlyingAsset	Underlying asset address
protocol	Protocol name (e.g. Aave, Lido)
categoryIds	Category IDs (JSON array)
details_liquidity	Pool liquidity in USD
details_totalTvl	Total TVL in USD
details_tradingVolume	Trading volume in USD
details_underlyingApy	Underlying asset APY
details_swapFeeApy	Swap fee APY earned by LPs
details_pendleApy	PENDLE incentive APY for LPs
details_impliedApy	Market implied APY (fixed yield if buying PT)
details_aggregatedApy	Total aggregated APY for LPs
details_maxBoostedApy	Max boosted APY with vePENDLE
details_ytFloatingApy	YT floating APY (variable yield)
details_lpRewardApy	LP reward APY
details_ptDiscount	PT discount to underlying (positive = discount)
details_voterApy	vePENDLE voter APY
details_totalPt	Total PT in pool
details_totalSy	Total SY in pool
details_totalActiveSupply	Total active LP supply

Input Parameters

Param	Type	Description
filter	array	Array of {field, op, value} objects (AND-combined)
sort	object	{field, direction: "asc" | "desc"}
include	array	Additional fields to include beyond address + chainId. Use ["all"] for everything.
limit	number	Max rows (default 20, max 50)
skip	number	Rows to skip for pagination
one	boolean	Return single row instead of array

Filter Operators

=, !=, >, <, >=, <=, LIKE — filters are AND-combined. LIKE is case-insensitive: plain text does substring match, use % and _ for pattern match.

Common Query Patterns

Active markets sorted by fixed yield:

{
  "filter": [{"field": "expiry", "op": ">", "value": "2026-03-30T00:00:00.000Z"}],
  "sort": {"field": "details_impliedApy", "direction": "desc"},
  "include": ["name", "expiry", "details_impliedApy", "details_liquidity"],
  "limit": 10
}

Markets by name pattern:

{
  "filter": [{"field": "name", "op": "LIKE", "value": "%ETH%"}],
  "include": ["name", "details_impliedApy"]
}

High-liquidity markets on a specific chain:

{
  "filter": [
    {"field": "chainId", "op": "=", "value": 42161},
    {"field": "details_liquidity", "op": ">", "value": 1000000}
  ],
  "sort": {"field": "details_liquidity", "direction": "desc"},
  "include": ["name", "details_liquidity", "details_impliedApy"]
}

get_chains — Supported Chains

Returns the list of blockchain network chain IDs where Pendle is deployed. Takes no parameters.

Always call get_chains when the user asks which chains Pendle supports — do NOT rely on a hardcoded list, as Pendle deploys to new chains over time.

---

get_asset — Pendle Token Lookup

Look up metadata for a Pendle token (PT, YT, SY, LP) or any underlying asset by chainId + assetAddress. Returns id, address, chainId, name, symbol, decimals, baseType, types, expiry, underlyingAsset, accountingAsset, and rewardTokens.

Note: This covers Pendle tokens and assets in the registry. For looking up standard ERC-20s by symbol (e.g. "USDC"), use resolve_token instead.

---

get_market — Deep Dive

For a single market deep-dive with full APY breakdown, pool metrics, and accepted input/output tokens, use get_market(chainId, marketAddress). Returns comprehensive data including:

• Token addresses: pt, yt, sy, underlyingAsset, accountingAsset
• Input/output tokens: inputTokens, outputTokens
• Reward tokens: rewardTokens
• APY data (nested data object): impliedApy, underlyingApy, underlyingInterestApy, underlyingRewardApy, ytFloatingApy, lpRewardApy, pendleApy, swapFeeApy, ptDiscount, voterApy, aggregatedApy, maxBoostedApy
• Pool metrics: liquidity, totalTvl, tradingVolume, tradingVolume7D
• Pool composition: totalPt, totalSy, totalActiveSupply
• Status: status, isWhitelisted, isWhitelistedPro, categoryIds

---

get_history — Market Snapshot

Returns current market data plus a 1-day-ago snapshot for comparison. Use this to assess recent APY trends and changes.

Parameters: chainId, marketAddress

Returns:

• currentData: impliedApy, underlyingApy, ytFloatingApy, ptDiscount, liquidity, totalTvl, tradingVolume, tradingVolume7D, swapFeeApy, pendleApy, aggregatedApy
• data1D: impliedApy, underlyingApy, liquidity, tradingVolume (1 day ago)

Compare currentData vs data1D to show APY movement direction.

---

get_external_protocols — External Protocol Integrations

Returns external protocol integrations (Aave, Morpho, Euler, restaking) for Pendle markets.

Parameters: chainId (optional), marketAddress (optional). If both provided, returns protocols for that specific market. If omitted, returns all protocols.

Common uses:

• Find which markets have PT accepted as collateral
• Compare supply/borrow APY across lending protocols
• Check max LTV for leverage strategies
• Identify LP collateral opportunities

---

Core Concepts

Token	Symbol Pattern	Role
PT (Principal Token)	PT-XYZ-DDMMMYYYY	Fixed yield — redeems 1:1 at maturity
YT (Yield Token)	YT-XYZ-DDMMMYYYY	Leveraged variable yield — decays to 0
SY (Standardised Yield)	SY-XYZ	Wrapped yield-bearing token
LP	PLP-XYZ-DDMMMYYYY	Pool share = market address

---

Yield Strategy Insights

Always include one of these after data display:

Condition	Interpretation	Advice
implied APY > underlying APY	Market expects yield to fall	PT opportunity — lock in fixed rate
implied APY < underlying APY	Market expects yield to hold/rise	YT opportunity — leveraged exposure
Near maturity (< 30 days)	PT converges to par	Hold PT -> redeem 1:1; LP IL reverses
LP APY > implied APY	LP outperforms pure PT	LP earns fees + PENDLE on top of fixed rate
External protocols accept PT	PT accepted as collateral	Loop possible: deposit PT -> borrow -> buy PT. See Leverage Strategy Details below.
External protocols accept LP	LP accepted in external protocol	LP collateral loop: extra yield layer on top of LP APY. Higher risk than PT loop due to IL.

Display rules:

• Omit External Protocol Integrations section if no protocols are available.
• Show — for optional APY/LTV fields that are absent.

Error Handling

Tool errors return structured JSON. Check the error message for guidance.

---

Supported Chains

Use get_chains to get the current list of supported chain IDs. Do NOT hardcode chain IDs — Pendle deploys to new chains over time.

---

Token Compatibility

Use get_market to check inputTokens and outputTokens. These are the addresses the market's SY wrapper natively accepts for minting/redeeming:

• If the user's token is in inputTokens -> direct deposit, no extra swap.
• If not -> the Pendle aggregator may still route through an intermediate swap (e.g., USDT -> USDC -> PT). Flag this as "via aggregator" and note added slippage risk.
• outputTokens governs withdrawal paths — check before recommending an exit.

Leverage Strategy Details

PT Looping

Concept: Use PT as collateral in a lending protocol, borrow stables, buy more PT, repeat.

Requirements: PT must appear in get_external_protocols results with maxLtv > 0.

Effective APY formula (single-loop approximation):

effectiveApy ~ impliedApy / (1 - LTV) - borrowApy * LTV / (1 - LTV)

Example — PT impliedApy = 8%, LTV = 0.75, borrowApy = 5%:

effectiveApy ~ 8% / 0.25 - 5% * 0.75 / 0.25
             = 32% - 15% = 17% effective fixed APY

Risk checklist before recommending:

1. Supply cap — is there room to deposit?
2. Liquidity in the lending pool — enough to borrow the target amount?
3. Buffer from liquidation: keep LTV well below max (suggest 10-15% safety margin)
4. PT price drops toward par at maturity — liquidation risk actually decreases over time for PT collateral
5. Borrow rate must stay below impliedApy for the loop to be profitable; check get_history for rate stability

Exit path: Repay loan -> withdraw PT -> sell PT or hold to maturity.

---

LP Collateral Loop

Concept: Deposit LP into a lending protocol, borrow stables, re-deploy capital into the same market (add liquidity again).

Requirements: LP must appear in get_external_protocols results.

Effective APY (simplified):

effectiveApy ~ aggregatedApy + (aggregatedApy - borrowApy) * LTV / (1 - LTV)

Higher risk than PT looping: LP value is more volatile (IL risk from APY swings). Use conservatively.

---

When to Suggest Looping

Condition	Suggest loop?
impliedApy - borrowApy > 3%	Yes — comfortable margin
impliedApy - borrowApy between 1-3%	Conditional — only if rate is historically stable
impliedApy < borrowApy	No — loop is immediately loss-making
Supply cap nearly full	No — may not be able to deposit PT
