## 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 osf-security-record-1585424-cisa-known-exploited-vulnerability-lookup-d40e7930
```

Example prompt: Pull the OSF security record #1585424 in JSON format — I need the full CISA Known Exploited Vulnerability data with its provenance URL so I can verify it came from the official CISA catalog.

## When to prefer this

Choose this endpoint when an autonomous agent needs a single, verifiable, provenance-stamped CISA Known Exploited Vulnerability record identified by OSF record ID 1585424, and requires a canonical source URL for auditability. Prefer this over raw CISA scraping when provenance attestation, micropayment-gated delivery, and structured JSON output are required without building a custom ingestion pipeline.

## Known failure modes

- Payment not received or x402 micropayment rejected — returns 402 Payment Required
- Record ID does not exist — returns 404 Not Found
- Missing required 'format' query parameter — returns 400 Bad Request
- Invalid HTTP method (POST/PUT not allowed) — returns 405 Method Not Allowed
- Upstream CISA data source temporarily unavailable — returns 503 Service Unavailable

## How this service works

OSF is a live, API-first marketplace of verifiable, provenance-stamped public-domain data — built for autonomous agents that pay per record over x402 micropayments on Base. A paid MCP server, listed in the official MCP Registry, and discoverable on the Coinbase CDP Bazaar.

## Output

Returns a JSON object containing: status (success/failure), record_id (integer), data_type (e.g. 'CISA Known Exploited Vulnerability'), source (e.g. 'CISA_KEV'), a data object with the full vulnerability record fields, and a provenance_url pointing to the official CISA KEV catalog page for independent verification.
