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
Returns a JSON object containing stress test results for the submitted portfolio, including scenario-based risk metrics, simulated drawdowns, vulnerability scores, and potentially correlation breakdowns under adverse market conditions.
Example use cases
Crypto portfolio crash scenario
“Stress test my portfolio with positions in BTC, ETH, and SOL against a 2022-style bear market crash scenario and show me the worst-case drawdown figures.”
Risk assessment before DeFi rebalance
“Before I rebalance my DeFi positions, can you run a stress test on my current holdings to see which assets are most exposed to a sudden liquidity crisis?”
Institutional risk report generation
“I need a stress test report on our fund's multi-chain crypto portfolio showing how it performs under three different adverse market scenarios — maximum drawdown, correlation spike, and a stablecoin depeg event.”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/portfolio-stress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quantitative, scenario-based stress testing of a crypto portfolio — especially useful before rebalancing, entering high-risk positions, or generating risk reports. At $4.16 per call it is priced for substantive analysis rather than lightweight queries. Prefer this over simpler price-check or balance endpoints when you need multi-scenario risk modeling rather than real-time prices.
Side effects
- Missing or malformed portfolio properties input returns a 400 error
- Insufficient USDC payment ($4.16 required) results in a 402 Payment Required response
- Empty or null properties field may return an incomplete or default analysis
- Unsupported asset types may be silently excluded from the stress test
- Network latency on Solana or Base payment rails may cause timeout
