E. Shaw and any other 13F filer) or its SEC CIK. Returns the latest (or any `period`) 13F-HR: total value, number of positions, each position (issuer, CUSIP, value, shares, % of portfolio, options marked put/call) merged across sub-managers, and against the quarter before: new positions, positions sold out, the biggest adds and cuts, and a plain-English `summary`. Managers with over $100M in US equities file within 45 days of each quarter's end. Unknown funds are not charged. You are only charged when a result is returned: invalid input (400) and upstream failures (4xx/5xx) are not settled. Costs $0.01 USDC per call via x402. Paid per call with x402 inside MCP (see the server instructions).
