How this service works
Risk x-ray for a whole watchlist or portfolio in one call. Pass `?tickers=AAPL,MSFT,NVDA` (up to 25; optional `?weights=`). Returns per-holding price, sector and cap, plus portfolio concentration (top-weight, Herfindahl, diversification score), sector concentration, market-cap distribution, weighted day performance and risk flags. Replaces dozens of per-holding calls. From x402stock
Output
Returns a structured portfolio analysis including: each holding's current price, day change percent, sector, market cap, and weight; portfolio-level day change percent; sector concentration HHI and label; market cap bucket distribution (mega/large/mid/small/micro); diversification score; top3 weight concentration; best and worst performing tickers today; and a list of risk flags (e.g. sector_concentration, few_holdings). Also indicates whether equal or custom weighting was applied.
Example use cases
Example prompt
“Can you run a portfolio x-ray on my three stocks — AAPL, MSFT, and NVDA — with equal weights, and tell me how diversified I am, which sectors I'm concentrated in, and which one moved the most today?”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/portfolio/xrayWhen to prefer
Use this endpoint when you need a holistic, multi-metric portfolio analysis (diversification, sector, market cap, risk flags, and performance) for a custom list of US stock tickers in a single call, rather than querying individual stock prices or metrics separately. Especially useful for AI agents that need structured, ready-to-interpret portfolio health summaries without building the analytics themselves.
Side effects
- Invalid or unrecognized ticker symbols return partial data or errors for those holdings
- Weights string length or format mismatch with tickers list causes validation error
- Missing required 'tickers' query parameter returns 400 error
- Payment in USDC not provided or rejected results in 402 Payment Required
- Market data may be delayed or unavailable outside trading hours
- Truncated or malformed query parameters may cause schema validation failure
