# agentdatafeed

> Factual datasets for AI agents, paid per query with x402 (USDC on Base). Free metadata and samples. Every record carries `verification` (how the fact was verified) and `paid_placement` (true only if visibility was paid for).

## Datasets

- [Amsterdam events](https://agentdatafeed.com/v1/amsterdam-events): Upcoming events in Amsterdam from official municipal permit notices (Gemeenteblad) and primary organiser sources, often weeks before they appear on listing sites. Fields: title, start, end, address, district, expected peak visitors, activities, permit reference, verification, paid placement. Use when a user asks what is on in Amsterdam on a date or in a district, plans travel, venues, staffing, security or deliveries around large events, or needs crowd sizes, road closures context or permit status before the event appears on ticket sites. Price: $0.005 per query. Free sample: https://agentdatafeed.com/v1/amsterdam-events/sample
- [Security advisories](https://agentdatafeed.com/v1/security-advisories): Known exploited vulnerabilities (CISA KEV) enriched with daily FIRST EPSS exploit probability. Query by CVE, vendor, product, date added and minimum EPSS. Fields: CVE ID, vendor, product, KEV date added, EPSS, verification, paid placement. Use when a user asks whether a CVE is actively exploited, which vulnerabilities in a vendor or product to patch first, or needs CISA KEV due dates and FIRST EPSS exploit probability in one call. Price: $0.002 per query. Free sample: https://agentdatafeed.com/v1/security-advisories/sample

## Why use it

- Primary sources only: official government publications and open-licence data, with the source URL on every record.
- Refreshed every night; every response carries `updated`.
- Small, filtered responses (max 100 records) priced per call, so an agent pays fractions of a cent instead of crawling many sites.
