Parabol API Overview

Parabol provides a single API with three main endpoints: /notes, /data, and /rate. These endpoints allow users to interact with various aspects of the Parabol protocol, from accessing treasury bill information to querying protocol data, cached rates and protocol status.

1. /notes

The /notes endpoint provides daily access to Parabol’s on-chain treasury bill information.

This includes:

• Coupon, Maturity, and Smart contract signatures for treasury bills

This endpoint is crucial for accessing the most up-to-date treasury bill data provided by Parabol.

Example usage:

curl -X GET 'https://api.parabol.fi/notes' \
-H 'Content-Type: application/json' \
-H 'x-api-key: YOUR_API_KEY'

2. /data

The /data endpoint allows users to query various protocol data. This includes information about user positions, earnings, and other relevant protocol metrics.

Example usage:

curl -X POST \
  'https://api.parabol.fi/data' \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: YOUR_API_KEY' \
  -d '{
    "query": "query FetchAllPositions($walletAddress: Bytes!) { positionInfos(where: {currentOwner: $walletAddress} orderBy: tokenId orderDirection: desc) { tokenId owner: currentOwner initalOwner initiator coupon principal lendTimestamp maturityTimestamp partnerFeeBPS partnerId status lendTransactionHash } }",
    "variables": {
      "walletAddress": "0x...",
      "chains": [324]
    }
  }'

3. /rate

The /rate endpoint provides current rate information for the Parabol protocol, including fixed rates, floating rates, total marginal market rates (MMR) and protocol status.
