Our Take

The real problem here isn't that AI agents are dumb — it's that they're confidently wrong with no way to verify, because nobody's built easy plumbing to the 250k+ government datasets that actually matter. Katzilla did that. One API key gets you SEC EDGAR, FDA recalls, Federal Register, BLS, FRED, the works — and every response includes a SHA-256 hash so your agent can cite exactly where the number came from instead of hallucinating. The free tier (2,500 requests/month for Data tool, no card required) is generous enough to build and test with, and the MCP integration for Claude Desktop, ChatGPT and Cursor means it's actually built for how developers work right now. 72 users and an 89-point Product Hunt launch isn't huge, but this is the kind of infrastructure tool that gets traction once people realize they need it — and honestly, they should have needed it yesterday.

Unified API that provides access to over 250k datasets from 30+ US and foreign government agencies with structured JSON responses optimized for AI agent ingestion. Each response includes structured citations with source URL, retrieval timestamp, and SHA-256 hash.

Problem It Solves
AI agents hallucinate government numbers and provide stale, half-right data without citations. When answers matter most (investment memos, compliance checks, research reports), the data breaks because agents cannot access primary government sources or cite what they read.
Target Customer
AI developers building agents that need reliable government data, compliance teams, investment researchers, and analysts who need data from SEC EDGAR, FDA recalls, Federal Register, Congress.gov, clinical trials, BLS, FRED, NOAA, USGS, Census and other government agencies.
Use Cases
Investment memo preparation, Compliance checks, Research reports, AI agent data retrieval with verifiable sources
Pricing Details
2,500 requests/month free for Data tool (no card required), 1,000 requests/month free for Scrape tool
Differentiator
Every response includes structured citation with source URL, retrieval timestamp, and SHA-256 data hash - enabling AI agents to stop guessing and cite exactly where data came from. Single API key for 30+ government agencies.
Why Now
AI agents are being deployed in production but lack reliable access to primary government data sources. Each agency has its own auth, rate limits, and response shape - wiring up 30+ agencies takes weeks of glue code. Katzilla provides the plumbing so agents can access verified government data with citations.
