## When to prefer this

Choose this endpoint when you need AI-curated, real-time stablecoin market intelligence without a long-term API subscription — ideal for pay-per-use agents, one-off DeFi research queries, or workflows that need current stablecoin metrics without managing API keys. Particularly suited for Base-native agents that can pay micropayments via x402 USDC.

## Known failure modes

- Payment not included or insufficient — returns HTTP 402 with payment requirements
- Invalid or malformed properties filter — returns 400 bad request
- Stablecoin market data temporarily unavailable — returns 503
- Network or Base blockchain connectivity issues causing payment verification failure
- Rate limiting or quota exceeded for high-frequency callers

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns AI-powered market intelligence for stablecoin assets, likely including metrics such as yields, liquidity depth, trading volume, market cap, and DeFi protocol data for major stablecoins. Response is provided after a $0.001 USDC micropayment via the x402 payment protocol.
