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.

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 |

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, aggregatedApydata1D: 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. |

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:
- Supply cap — is there room to deposit?
- Liquidity in the lending pool — enough to borrow the target amount?
- Buffer from liquidation: keep LTV well below max (suggest 10-15% safety margin)
- PT price drops toward par at maturity — liquidation risk actually decreases over time for PT collateral
- 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 |
