How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
A normalized list of blockchain networks where the queried stablecoin is deployed, potentially including chain names, chain IDs, contract addresses, and deployment metadata. Response is edge-cached and sourced from aggregated public on-chain data providers.
Example use cases
Multi-chain stablecoin deployment audit
“Give me a full list of all chains where USDC is currently deployed so I can decide which networks to support in my DeFi app.”
L2 stablecoin availability check
“I'm building on Base and Arbitrum — can you check which of those chains have major stablecoins like USDT and DAI available on-chain?”
Cross-chain yield strategy research
“I'm researching stablecoin yield strategies across chains — can you pull which networks support DAI so I know where liquidity exists?”

Endpoint
GEThttps://x402.santyvv.com/api/defi/stablecoin-chains?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need stablecoin-to-chain mapping data without setting up an account or API key, and are comfortable paying $0.01 USDC per call via the x402 micropayment protocol on Base. Ideal for agents that need on-demand, keyless access to normalized DeFi chain data with edge caching and multi-source fallback, especially in automated or ephemeral workflows where credential management is impractical.
Side effects
- Payment not received or insufficient USDC balance — returns HTTP 402 with payment requirements
- Invalid or unsupported stablecoin identifier — may return empty list or 400 error
- Upstream data provider unavailable — fallback sources used but may result in partial data
- Rate limit or network congestion on Base — payment transaction may fail or delay
- Malformed request parameters — returns 400 bad request
