CongressInvests vs Goldprice.dev

CongressInvests tracks U.S. congressional stock trades from official Senate EFD and House Clerk disclosures, refreshed every six hours, with per-ticker trade history, a global feed, and a Pro-only AI-generated trend narrative (sentiment plus notable member patterns, cached 24 hours per ticker). The core REST API is keyless for up to 100 requests/day; a $29/month Pro plan adds an X-Api-Key header for webhook alerts, the AI trend endpoint, and higher limits. It ships official Python and Node.js SDKs and markets itself against paid-only competitors like QuiverQuant and Unusual Whales.

Goldprice.dev is a commodity-pricing API returning live XAU/XAG/copper spot prices across 31 currencies (cross-checked via exchangerate.dev with an ECB fallback), COMEX gold futures and GLD ETF data, and over a decade of daily XAU/USD history, with every price citing its source and published methodology. Access is anonymous and keyless by default at a modest rate limit; a free API key raises throughput, and paid tiers add per-country physical dealer pricing, a volatility/probability surface, a real-time SSE/WebSocket feed, and an MCP server on every plan. A live Origin-header probe against the real API host (api.goldprice.dev) found no Access-Control-Allow-Origin header, so CORS resolves to `no` — the stored `unknown` was unresolved, not confirmed open.
