How this service works
OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.
Output
A JSON object containing stress test results for the provided portfolio, likely including scenario-based risk metrics, drawdown estimates, vulnerability scores per asset, and overall portfolio resilience indicators under simulated adverse market conditions.
Example use cases
Crypto portfolio bear market simulation
“I have a mix of BTC, ETH, and SOL positions — run a stress test to show me how my portfolio would perform if the market dropped 40% like it did in 2022.”
DeFi holdings risk assessment
“Stress test my DeFi portfolio holdings and give me a breakdown of which positions are most vulnerable under a liquidity crisis scenario.”
Pre-trade risk check before rebalancing
“Before I rebalance, can you run a stress test on my current portfolio to see how the new allocation would hold up under a severe market shock?”
Technical details
Endpoint
GEThttps://api.losbeto.xyz/portfolio-stress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, paid-per-call portfolio stress test without standing up your own risk infrastructure. It is particularly useful for AI agents operating in crypto/DeFi contexts that already support x402 USDC micropayments on Solana or Base, and need on-demand scenario analysis rather than a continuously monitored risk service.
Side effects
- Missing or malformed portfolio properties input returns an error
- Invalid asset identifiers in portfolio configuration may cause partial or empty results
- Payment failure (insufficient USDC balance or wrong chain) blocks the request with HTTP 402
- Upstream data unavailability may cause timeout or incomplete stress scenarios
- Unsupported asset classes may be silently ignored or return null metrics
