About Mocktail

Self-hosted mock API server + dashboard in one ~25 MB binary. Define endpoints, generate realistic data, test errors and latency, and inspect live traffic. Model the responses your app expects, headers, delays, even the flaky 401, and let Mocktail keep the data lively. Keep responses fixed, generate fresh values on every request ( uuid, email, price, name ), or swap real fields for fake data when you need to anonymize a response. Create an endpoint, hit Test right from the dashboard, and watch it land in the live stream, method, status, latency, and the exact response and headers served.

About Stock News API

REST API for relevance-scored, ticker-linked financial news: a real-time stock news API for trading bots, AI agents, and dashboards. Free tier, no credit card. Every article arrives scored for relevance and linked to tickers, so a trading bot or an agent backend can filter the wire at request time. Filter server-side Symbol, category, minimum relevance and delta polling are query params, so the wire is cut before it costs you a token. Enough to evaluate the feed and build a prototype.
