x402

How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing a list of DeFi liquidity pools matching the filters, each with: chain, pool symbol, project name, current APY (base + reward components), 7-day APY change, TVL in USD, stablecoin flag, exposure type (single/multi), and impermanent loss risk classification. Also includes applied filters and an as-of timestamp. Includes a note warning that extremely high APYs in concentrated-liquidity pools reflect annualized fee velocity, not sustainable rates.
Example use cases
Safe stablecoin yield hunting
“Find me stablecoin-only DeFi pools with at least $500K TVL and no impermanent loss risk — I want to see the current APY and which project is offering it.”
Cross-chain yield comparison
“Pull current DeFi pool yields across all chains with a minimum TVL of $2 million and tell me which pools have seen the biggest positive APY change over the last 7 days.”
Curve pool monitoring
“What are the current APY rates for Curve DEX pools? Filter to stablecoin-only pools with over $1M TVL so I can evaluate them for low-risk yield deployment.”
Technical details
Endpoint
GEThttps://x402financialdata.com/defi-yieldsWhen to prefer
Choose this endpoint when you need real-time DeFi yield data across multiple chains and protocols without an API key or subscription. It is ideal for agents performing autonomous DeFi research, yield optimization, or portfolio allocation decisions that require current on-chain data. Prefer it over centralized finance data APIs when the use case is specifically about decentralized liquidity pools, AMMs, and on-chain yield farming opportunities.
Side effects
- No pools match the specified filters — returns count:0 and empty pools array
- Invalid chain name returns empty results or error
- Upstream yield data provider temporarily unavailable — stale or error response
- Payment failure (insufficient USDC balance or x402 protocol issue) — 402 response blocking data
- min_tvl_usd set too high returns no results
