## 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 filingspulse-municipal-bond-disclosure-search-691ed8a1
```

Example prompt: Can you pull up the municipal bond disclosures for CUSIP 13063DAB2 — I want to know what the issuer has filed on EMMA and get a plain-language summary of the key details?

## When to prefer this

Choose this endpoint when you need to research a specific municipal bond by its 9-character CUSIP or by issuer name, and want AI-synthesized summaries of EMMA/MSRB disclosure filings rather than raw document retrieval. Prefer this over general SEC filing endpoints when the target security is a municipal bond (not a corporate equity or ETF). Useful for fixed-income analysts, retail investors holding muni bonds, or agents conducting due diligence on tax-exempt debt instruments.

## Known failure modes

- Invalid or unknown CUSIP returns no results or an error
- Issuer name too ambiguous may return multiple or mismatched results
- EMMA/MSRB data may lag real-time disclosures
- Empty response schema suggests limited structured output guarantees
- Payment failure if x402 micropayment of $0.15 USDC not completed
