Pendle Backend Data API
REST API for offchain Pendle data — markets, assets, prices, user positions, transactions, points, and governance. Cross-chain endpoints (`GET /v2/markets/all`, `GET /v1/assets/all`, `GET /v1/prices/assets`) return data spanning every supported chain in one call and are the recommended entry points for new integrations. Chain-scoped endpoints (`/v3/{chainId}/markets/{address}/historical-data`, `/v5/{chainId}/transactions/{address}`) provide deep market history with optional APY breakdown and per-address transaction history. The pricing response includes a partial-success `errors` array so callers can handle non-fatal missing-asset cases without retrying.
