Beefy API

Last Update: August 2023

This page provides further details about the functionality and operation of Beefy's REST API, which powers our web application, dashboard and pages on third party sites.

You can access the API at https://api.beefy.finance/, and the public repository is available on the Beefy GitHub. The API is maintained under the MIT license, with further details available on the GitHub repo.

Endpoints

Our API offers a range of public endpoints covering the full selection of data required for our web app, backend and dashboard, as well as some third party services.

Beefy Vault Endpoints

Endpoints developed for use by the Beefy Application to display vaults' live characteristics and performance to our users.

GET /vaults

Provides live information about each Beefy vault, including retired (eol) vaults.

The information includes fields for the relevant vault's name/ID, chain, token, underlying assets, related contracts and current status. It also includes the "risks" field, which lists the vault's features taken from the matrix of risk factors used to calculate a vault's safety score.

// Sample response for the /vaults endpoint (e.g. Polygon aTriCrypto3 vault)

Field Notes:

  • id - the unique identifying string assigned to each vault, including separate versions of the same vault.

  • tokenAddress - the contract address for the main deposit asset, typically an LP token.

  • earnedTokenAddress - the contract of the token which is earned by the strategy used by the vault. For most Beefy vaults, this is the same as the vault contract, because the strategy is autocompounding. For earnings pool vaults (which don't autocompound), this will be the native token of the chain or protocol that the vault relates to.

  • earnContractAddress - the address of the Beefy vault contract which handles deposits and withdrawals and issues the mooVault token to users.

  • status - shows whether a vault is live ("active") or retired ("eol").

  • assets - the underlying assets at the base of the relevant vault's stack (typically the assets included in the LP that the vault is built on).

  • strategyTypeID - indicates what type of strategy is being utilised by the vault (e.g. "single" asset, "lp", "multi-lp", etc).

  • risks - a list of the vault's applicable features taken from the matrix of factors used to calculate a vault's safety score.

  • network - the relevant blockchain that the vault resides on.

  • createdAt - the block of the relevant blockchain where the vault was created.

  • strategy - the address of the strategy contract currently in use by the vault.

  • lastHarvest - the block of the relevant blockchain where the vault was last harvested - i.e. where profits were collected from the strategy (and autocompounded, if applicable).

  • pricePerFullShare - the current average price (denominated in the deposit asset, e.g. the underlying LP token) for each whole share of the vault's total issued share capital, reflecting the total value invested into the vault over its life divided by the number of shares of the vault issued.

Subgraph

Please note that Beefy does not currently operate or maintain any subgraphs for our protocol.

Our friends at Messari have developed a subgraph for our presence on BSC chain, which is available at https://api.thegraph.com/subgraphs/name/messari/beefy-finance-bsc, and on The Graph's website (ID: QmfEtMEgjik9FSZdqAmp2DkNFG4M9TK4Go8uyCUj8EVxY6). Beefy has had no role in the development or maintenance of this subgraph. Please direct any questions or requests for assistance in relation to this subgraph directly to Messari.

Other Data

For any readers seeking further information about Beefy and our protocol's performance, please head to the #📊-beefy-data channel in our Discord server. We'll be happy to answer any questions you may have there and you're welcome to inspect the history of our discussions in that channel for further background into our data work.

You'll also find in that channel a collection of weekly reports on the breakdown of our $BIFI token across our different chains and vaults, which are lovingly prepared by core contributor EPETE.
