BitcoinYield API

One entry per asset with its best current yield across DeFi and CeFi, its A-D risk grade and a link to the full comparison. best_apy is a percent. No key required. Optional asset, stablecoin and max_risk (A to D: only offers graded at or below that letter) filters.

Every normalized live yield opportunity (platform, asset, product type, chain, APY, base/reward split, TVL, risk grade). Filter with asset, provider (platform), type, limit.

Narrow /api/v1/prices to exactly the yield you want. asset is the symbol or slug (usdc, btc), provider is the platform (aave-v3, nexo), and type is how the yield is produced, one of defi_lending, savings, defi_lp, farm, defi_vault, liquid_staking, restaking, fixed, synthetic, backstop, private_credit, rwa_fund, cefi_earn, or structured_option (the methodology explains each).

curl -H "Authorization: Bearer by_live_..." \

Connect any MCP client (Claude, Cursor, or an autonomous agent) to the hosted server over Streamable HTTP (protocol 2026-07-28, with the earlier handshake still supported). Tool: list_yields returns the best current yield per asset across DeFi and CeFi with its risk grade, optionally capped with max_risk. Nothing to install.
