x402
x402 Safe Stablecoin Yields — DeFi Due-Diligence Pool Screener is a paid API for AI agents from x402-data-api.sigrunner.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-20).
Returns a curated, pre-screened list of stablecoin yield pools (from DefiLlama) filtered for safety: TVL > $5M, APY 1–25%, enriched with protocol age and hack history, sorted safest-first.

How this service works
Vetted stablecoin yields: top stablecoin pools (DefiLlama, TVL>$5M, APY 1-25%) joined with each protocol's age and hack history, safest-yield first; optional ?chain= & ?limit=. No required params. Use when an agent needs where to park stablecoins with due-diligence already applied.
Output
A JSON object containing an array of pools, each with: project name, chain, stablecoin symbol, APY (number), TVL in USD (integer), protocol age in days, and a boolean indicating whether the protocol has been hacked before. Results are pre-filtered (TVL > $5M, APY 1–25%) and sorted safest-first.
Example use cases
Idle treasury stablecoin allocation
“I've got idle USDC in our treasury and want to earn yield safely — can you find me the top 5 vetted stablecoin pools on Ethereum that have never been hacked and have been around a while?”
Cross-chain yield comparison for a DeFi agent
“Compare the safest stablecoin yield opportunities across all chains and show me the top 15, ranked by safety first — I need protocol age and hack history included.”
Arbitrum stablecoin yield scouting
“What are the best stablecoin pools on Arbitrum right now? I want yields that have already been screened for TVL and hack risk, give me up to 20 results.”
Technical details
Endpoint
GEThttps://x402-data-api.sigrunner.workers.dev/defi/safe-yields?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to make a stablecoin yield allocation decision and wants due diligence already applied — specifically when you need hack history and protocol age baked into the ranking rather than raw APY lists. Prefer this over generic DeFi yield APIs (like the sibling top-pools endpoint) when safety filtering and risk metadata matter. Best when the agent doesn't want to run its own TVL or hack-history filters.
Side effects
- Invalid chain parameter returns empty pool list or error
- Limit exceeding 30 is clamped or rejected
- DefiLlama data source temporarily unavailable causes stale or empty response
- Network timeout from Cloudflare Workers edge if upstream DeFi data is slow
