How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns current stablecoin market capitalization data, likely including total market cap figures and possibly per-stablecoin breakdowns (e.g. USDC, USDT, DAI). Response schema is minimal/undocumented; expect a JSON object with market cap values.
Example use cases
DeFi dashboard stablecoin overview
“Pull the latest stablecoin market cap data so I can display the total stablecoin market size on my DeFi analytics dashboard.”
Macro crypto market analysis
“I'm writing a market report — what's the current combined market cap of stablecoins across the market right now?”
Stablecoin dominance monitoring
“Check the stablecoin market cap for me so I can track whether stablecoin dominance is growing or shrinking versus the broader crypto market this week.”

Endpoint
GEThttps://acp-x402-discovery.onrender.com/x402/stablecoin-mcap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need stablecoin market cap data and are operating in a crypto-native, x402-payment-enabled environment settled in USDC on Base. It is a micro-cost ($0.001 USDC) pay-per-call option suitable for agents that already integrate x402 payment flows. Prefer established data providers (CoinGecko, CoinMarketCap) if you need richer schema documentation, high reliability, or traditional API key authentication.
Side effects
- Payment failure if USDC balance on Base is insufficient or x402 payment not properly configured
- 402 Payment Required if payment header is missing or malformed
- Empty or stub response due to low crawl quality and undocumented schema
- Service unavailability on Render free-tier hosting (cold starts, downtime)
- Rate limiting or access errors if the upstream data source is unavailable
