Here are the top 3 Fresh APIs and Tools for AI Builders recently launched in the past few weeks...

1. CoinGecko Crypto Treasury API - September 19, 2025

Details: https://cryptobriefing.com/coingecko-launches-api-for-crypto-treasuries-data-access/

CoinGecko launched treasury tracking endpoints that show which governments and companies hold crypto. Perfect for building investment tracking apps, market sentiment tools, or crypto portfolio analyzers.

Money opportunities:

Build treasury tracking dashboards for crypto funds
Create alerts when major holders buy/sell
Develop corporate crypto adoption reports for consulting firms

How to tap in:

Use their new /treasuries/bitcoin endpoint to track institutional holdings. Build automated reports showing who's accumulating or dumping.

Sample prompt:

Build me a crypto treasury tracker that monitors when governments and companies change their Bitcoin holdings. I want to detect when major institutions buy or sell, calculate the total institutional ownership percentage, and send alerts when holdings change by more than 10%.

2. Google Trends API Alpha - September 2025

Details: https://developers.google.com/search/blog/2025/07/trends-api

Google finally released programmatic access to Trends data with 5 years of consistent data. Unlike the website, this gives you scalable access to search interest data.

Money opportunities:

Build trend-based content strategy tools for agencies
Create market research dashboards for businesses
Develop SEO opportunity finders based on search trends

How to tap in:

Apply for alpha access at developers.google.com/search/apis/trends. Focus on research/journalism use cases since they're not prioritizing SEOs yet.

Sample prompt:

Create a content opportunity finder that uses Google Trends API to identify trending topics in my industry. I want it to compare search volume across different regions, predict which trends are growing, and suggest content topics before they peak.

3. HubSpot Date-Based API v2025-09 - September 2025

Details: https://developers.hubspot.com/changelog/new-and-improved-apis-fall-spotlight-2025

HubSpot switched to date-based versioning (like /2025-09/) instead of v1, v2, v3. This makes API changes predictable and gives you 18 months minimum support.

Money opportunities:

Build CRM integrations with guaranteed stability
Create marketing automation tools for agencies
Develop customer data sync services

How to tap in:

Migrate existing integrations to the new versioning system. Build tools that leverage the improved Commerce payments CRUD operations and enhanced Campaigns API.

Sample prompt:

Help me migrate my HubSpot integration from v3 to the new 2025-09 date-based API. I need to update my CRM sync tool that handles contact management, deals tracking, and campaign analytics. Show me how to handle the new versioning system and take advantage of the improved Commerce payments features.
