Is there a crypto lending rates API?

Yes. The Yield API returns live and historical lending rates for 610+ assets across 55+ CeFi and DeFi providers — for example GET /api/v1/rates/USDC?category=lending — with per-rate freshness and source signals. The same data powers the lending rates comparison pages.

Is there a staking rewards API?

Yes. Staking reward rates are served from the same endpoint with category=staking, covering validators, exchanges and liquid staking providers, normalized to the same JSON schema as lending and borrowing rates.

Can I get crypto rates for a specific asset?

Yes. Requesting an asset without a category filter — for example GET /api/v1/rates/ETH — returns every rate category for that asset in a single call, lending, staking and borrowing side by side, which is the shape most apps and AI agents want for per-coin views.

Does the API cover both CeFi and DeFi?

Yes. Every rate is classified CeFi or DeFi and fixed or flexible, so you can filter or compare across both in one response instead of stitching together separate sources.

Can AI agents use the Yield API?

Yes. The REST API has a public OpenAPI spec and a free tier, and the same data layer is exposed as MCP tools for agents — connect via the hosted MCP endpoint or the @bitcompare/mcp-server npm package.

Freshness & trust

Know how fresh and trustworthy every rate is.

Every rate carries freshness, source and confidence — so you can trust what you ship.

How often rates refresh

Rates refresh continuously, typically every 5 minutes, and each carries a freshness signal.

What "verified" means

Verified rates are confirmed against the provider's own source, not estimated.

How source is captured

Each rate records its source type — provider API, partner feed or manual review.

What confidence signals mean

A confidence label flags how reliable a rate is, so you can filter low-confidence data.

Why rates differ

Rates vary by region, asset, tier, lockup, balance and provider terms — exposed where available.

Everything you need to integrate.

Docs, schema and agent-ready surfaces — built for developers and AI agents alike.

FAQ

Frequently asked questions

Is there a crypto lending rates API?: Yes. The Yield API returns live and historical lending rates for 610+ assets across 55+ CeFi and DeFi providers — for example GET /api/v1/rates/USDC?category=lending — with per-rate freshness and source signals. The same data powers the lending rates comparison pages.
Is there a staking rewards API?: Yes. Staking reward rates are served from the same endpoint with category=staking, covering validators, exchanges and liquid staking providers, normalized to the same JSON schema as lending and borrowing rates.
Can I get crypto rates for a specific asset?: Yes. Requesting an asset without a category filter — for example GET /api/v1/rates/ETH — returns every rate category for that asset in a single call, lending, staking and borrowing side by side, which is the shape most apps and AI agents want for per-coin views.
Does the API cover both CeFi and DeFi?: Yes. Every rate is classified CeFi or DeFi and fixed or flexible, so you can filter or compare across both in one response instead of stitching together separate sources.
Can AI agents use the Yield API?: Yes. The REST API has a public OpenAPI spec and a free tier, and the same data layer is exposed as MCP tools for agents — connect via the hosted MCP endpoint or the @bitcompare/mcp-server npm package.
