## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stratalize-13f-holdings-delta-16181a52
```

Example prompt: Pull the quarter-over-quarter 13F holdings delta for Bridgewater Associates — use their CIK 1350694 — so I can see what positions they added, dropped, or resized between the two most recent filing periods.

## When to prefer this

Use this endpoint when you specifically need to compare two consecutive quarters of 13F-HR filings for an institutional manager and want pre-computed delta scaffolding. Prefer over raw SEC EDGAR queries when you need attested, signed responses with verifiability receipts. Ideal for compliance, due diligence, or investment research workflows requiring QoQ context on institutional holdings changes.

## Known failure modes

- Invalid or unrecognized CIK returns an error — verify the CIK matches an SEC EDGAR institutional filer
- Ticker not found or not associated with a 13F filer — not all institutions file by ticker
- Insufficient 13F history (e.g. manager only has one filing) means no prior quarter available for delta
- SEC EDGAR data lag may mean the most recent quarter is not yet ingested
- Payment of $0.5 USDC required per call via x402 protocol — unpaid requests will be rejected

## How this service works

Stratalize — attested finance, legal, healthcare, and compliance intelligence. Signed, independently verifiable receipt on every call (trust.stratalize.com/verify). Use when comparing institutional 13F-HR filing quarters for QoQ holdings change context. Returns current and prior quarter filing pairs with delta summary scaffolding.

## Output

A pair of current and prior quarter 13F-HR filing records for the specified institutional manager, along with a delta summary scaffold showing changes in holdings — positions added, removed, or resized — between the two quarters. Each response includes a signed, independently verifiable receipt from trust.stratalize.com.
