🚀 altFINS Builder Challenge: Build with Our API & MCP - Win Startup Plan 1-Year (valued at $948)
We’re launching a builder challenge to showcase what’s possible with the altFINS API and MCP server.
Whether you’re already using API / MCP or just exploring, this is your chance to build something real, get it in front of crypto community, and win a full year of altFINS Startup Plan (10 winners).
Turn your 1,000 free API credits into 300,000 monthly credits with Startup API plan for 1 year.
🎯 The Challenge
Use the altFINS API and/or altFINS MCP server to build a product, tool, or piece of content that demonstrates real value for crypto traders and investors.
You decide the format. Some directions to consider:
-
AI Agent: A trading assistant, signal bot, or research agent powered by altFINS data (great fit for the MCP server + Claude/GPT/other LLMs)
-
Dashboard: A custom analytics dashboard, screener UI, or portfolio tracker pulling altFINS metrics
-
Algorithm / Strategy: A backtested trading strategy, alert system, or screener logic built on altFINS signals, patterns, or technical analysis data
-
Research / Analysis: A deep-dive market report, sector analysis, or quantitative study using altFINS data
-
Educational Content: A tutorial, course, or blog series teaching others how to build with altFINS
-
Surprise us: Anything else that creatively leverages our data
The MCP server makes it especially easy to plug altFINS directly into Claude, Cursor, no boilerplate, just natural-language access to live market data.
Try vibe coding with Manus, Codex, Claude Code, Lovable or other coding tools to create web apps, websites or dashboards using altFINS API.
