get_markets — SQL-backed Market Query

Queries from local SQLite database (0 API calls, instant response). Data refreshes every 5 minutes.

Column Names (flat schema)

All columns use a flat naming convention. Nested details.* fields are prefixed with details_:

Column	Type	Filterable	Description
address	TEXT	✓	Market address (= LP token address)
chainId	INTEGER	✓	Chain ID
name	TEXT	✓	Market name
expiry	TEXT	✓	ISO 8601 expiry date
pt	TEXT	✓	PT token ID ("chainId-address" format)
yt	TEXT	✓	YT token ID
sy	TEXT	✓	SY token ID
underlyingAsset	TEXT	✓	Underlying asset ID
isNew	INTEGER	✓	1 if new market
isPrime	INTEGER	✓	1 if prime market
details_liquidity	REAL	✓	AMM liquidity in USD
details_totalTvl	REAL	✓	Total TVL in USD
details_tradingVolume	REAL	✓	24h trading volume USD
details_underlyingApy	REAL	✓	Variable APY (decimal)
details_swapFeeApy	REAL	✓	Swap fee APY
details_pendleApy	REAL	✓	PENDLE emissions APY
details_impliedApy	REAL	✓	Fixed/implied APY (decimal)
details_aggregatedApy	REAL	✓	Total LP APY
details_maxBoostedApy

Filter Operators

=, !=, >, <, >=, <=, LIKE — filters are AND-combined. points and externalProtocols are JSON blobs and cannot be used as filter fields; apply post-fetch filtering in your reasoning after parsing them.

---

points Column — Point Reward Programs

Each market row includes a points JSON string. Parse it to get PointMetadataEntity[]:

interface PointMetadataEntity {
  key: string;             // reward program identifier, e.g. "eigen", "sats"
  type: "multiplier" | "points-per-asset";
  pendleAsset: "basic" | "lp"; // "lp" = LP holders earn; "basic" = PT/YT holders earn
  value: number;           // multiplier magnitude or points-per-asset rate
  perDollarLp: boolean;    // if true, value is per dollar of LP
}

When to use: surface markets that reward users with external protocol points (EigenLayer, Babylon, etc.) on top of Pendle yield.

Fetch-then-filter pattern for points:

1. get_markets({ limit: 100, sort: { field: "details_impliedApy", direction: "desc" } })
2. For each row, JSON.parse(row.points ?? "[]")
3. Filter rows where parsed array length > 0
4. Rank by value (multiplier magnitude) or by implied APY

Interpreting point rewards:

type	pendleAsset	Meaning
multiplier	basic	PT/YT holders earn value× the base points rate
multiplier	lp	LP holders earn value× the base points rate
points-per-asset	basic	PT/YT holders earn value points per asset per day
points-per-asset	lp	LP holders earn value points per dollar of LP per day (if perDollarLp: true)

---

externalProtocols Column — External Yield Integrations

Each market row includes an externalProtocols JSON string for quick inspection on a single market. For filtering and ranking across markets, use get_external_protocols instead (SQL-backed, instant).

The JSON shape:

interface MarketExternalProtocolsEntity {
  pt:      ExternalProtocolMetadataEntity[];  // protocols that accept PT as collateral
  yt:      ExternalProtocolMetadataEntity[];  // protocols that accept YT
  lp:      ExternalProtocolMetadataEntity[];  // protocols that accept LP
  crossPt: ExternalProtocolMetadataEntity[];  // cross-chain PT integrations
}

Prefer get_external_protocols over parsing JSON from get_markets whenever you need to filter, sort, or compare protocols across multiple markets.

Common Query Patterns

Active markets sorted by fixed yield:

{
  "filter": [{"field": "expiry", "op": ">", "value": "2026-03-22T00:00:00.000Z"}],
  "sort": {"field": "details_impliedApy", "direction": "desc"},
  "limit": 10
}

Markets by name pattern:

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

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"}
}

---

get_chains — Supported Chains

Returns the list of blockchain network chain IDs where Pendle is deployed. Takes no parameters. Data refreshes every 5 minutes.

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 Pendle-specific tokens (PT, YT, SY, LP) by chainId + address. Returns name, symbol, decimals, tags, expiry.

Note: This only covers Pendle tokens. For standard ERC-20s (USDC, WETH), 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. It merges 3 API calls internally and returns comprehensive data.

---

get_history — Time Series

Historical APY, TVL, and price data for a market. Use fields to select specific metrics and timeFrame for granularity (hour/day/week).

---

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

get_external_protocols — External Protocol Query

Queries the market_external_protocols table (0 API calls, instant). Data is exploded from MarketExternalProtocolsEntity at sync time — one row per (market, slot, protocol). Set includeMarket: true to JOIN the markets table and get market_name, market_expiry, details_impliedApy, details_underlyingApy, details_aggregatedApy in each result.

Filterable Columns

Column	Type	Description
chainId	INTEGER	Chain ID
market	TEXT	Market address
slot	TEXT	pt, yt, lp, or crossPt
protocol_id	TEXT	Protocol identifier, e.g. aave, morpho, euler
protocol_name	TEXT	Human-readable protocol name
protocol_category	TEXT	e.g. lending, restaking
liquidity	REAL	USD liquidity in this integration
borrowApy	REAL	Borrow APY (decimal)
supplyApy	REAL	Supply/collateral APY (decimal)
totalSupply	REAL	Total supplied amount
supplyCap	REAL	Supply cap
maxLtv	REAL	Max loan-to-value ratio

JOIN-only Sort Fields (require includeMarket: true)

market_name, market_expiry, details_impliedApy, details_underlyingApy, details_aggregatedApy

Common Query Patterns

All lending protocols that accept PT as collateral, best supply APY first:

{
  "filter": [{"field": "slot", "op": "=", "value": "pt"},
             {"field": "protocol_category", "op": "=", "value": "lending"}],
  "sort": {"field": "supplyApy", "direction": "desc"},
  "includeMarket": true
}

PT markets on Arbitrum usable as Aave collateral:

{
  "filter": [{"field": "chainId", "op": "=", "value": 42161},
             {"field": "slot", "op": "=", "value": "pt"},
             {"field": "protocol_id", "op": "=", "value": "aave"}],
  "includeMarket": true
}

Best borrow rate against LP (leveraged LP strategy):

{
  "filter": [{"field": "slot", "op": "=", "value": "lp"}],
  "sort": {"field": "borrowApy", "direction": "asc"},
  "includeMarket": true,
  "limit": 10
}

Highest LTV for PT collateral (max leverage):

{
  "filter": [{"field": "slot", "op": "=", "value": "pt"},
             {"field": "maxLtv", "op": ">", "value": 0}],
  "sort": {"field": "maxLtv", "direction": "desc"},
  "includeMarket": true
}

All integrations for a specific market:

{
  "filter": [{"field": "market", "op": "=", "value": "0x..."}],
  "includeMarket": true
}

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
points non-empty	Market has external point rewards	Factor in effective APY of points on top of base yield — can dominate for high-multiplier programs
externalProtocols.pt non-empty	PT accepted as collateral	Loop possible: deposit PT → borrow → buy PT. Effective APY ≈ impliedApy / (1 - LTV) - borrowApy × LTV / (1 - LTV). See Leverage Strategy Details below.
externalProtocols.lp non-empty	LP accepted in external protocol	LP collateral loop: extra yield layer on top of LP APY. Higher risk than PT loop due to IL.
externalProtocols.borrowApy available	Lending market for this PT	If impliedApy > borrowApy: loop is profitable. If impliedApy < borrowApy: loop destroys value — do not recommend.

### Tokens: PT={pt} YT={yt} SY={sy}

### Point Rewards  ← omit section if points array is empty

|------------|----------|------------|------------|---------|-----------|
| PT         | {name}   | X.XX%      | X.XX%      | XX%     | $X        |
| LP         | {name}   | X.XX%      | —          | —       | $X        |

Display rules:

• Omit Point Rewards section entirely if JSON.parse(points) is an empty array or null.
• Omit External Protocol Integrations section if all four slot arrays (pt, yt, lp, crossPt) are empty.
• Show — for optional APY/LTV fields that are absent.
• For crossPt, label the Token Slot column as "Cross-PT".

Error Handling

Tool errors return structured JSON with error.code and error.retryable. If retryable: true, wait and retry. Check error.action 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 tokensIn and tokensOut. These are the addresses the market's SY wrapper natively accepts for minting/redeeming:

• If the user's token is in tokensIn → 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.
• tokensOut 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 with slot=pt and 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. supplyCap from get_external_protocols — 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 maxLtv (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 with slot=lp.

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
supplyCap nearly full	No — may not be able to deposit PT
isVolatile = true	Caution — underlying price movement can trigger liquidation
