Trend Seeker Public API - Integrate Business Idea Data Into Your Apps

Today we're releasing the Trend Seeker Public API - a RESTful API that gives developers direct access to our database of validated business ideas, market signals, and trend data.

Whether you're building a startup research tool, a newsletter that curates business opportunities, or an internal dashboard for your team - you can now pull real-time data from our pipeline programmatically.

What the API provides

The API exposes the same data that powers trend-seeker.app:

• Business ideas - each validated against real online discussions, with evidence scores, categories, and confidence tiers
• Source posts - the actual Reddit threads and forum posts that surfaced each idea
• Market metrics - competition level, monetization potential, and opportunity scores (Pro tier)
• Categories and keywords - for filtering and discovery

Free vs Pro

The API is available to everyone, with the same free/pro split as our website:

Free tier (no key required)

• 10 requests per minute
• 20 results per page, browse up to 100 ideas
• Basic fields: title, tagline, categories, confidence tier, date
• Up to 5 source posts per idea

Pro tier (included with Pro subscription)

• 120 requests per minute
• 100 results per page, no offset limits
• Full data: evidence scores, market metrics, validation scores, all fields
• Up to 100 source posts per idea
• Solution approach and "why now" analysis for premium ideas

Getting started

The simplest way to try it:

curl "https://api.trend-seeker.app/v1/ideas?limit=5"

That returns the top 5 business ideas with basic fields. No authentication needed.

For full access, generate an API key from your account settings and pass it as a Bearer token:

curl "https://api.trend-seeker.app/v1/ideas?limit=10&categories=saas" \
  -H "Authorization: Bearer tskr_your_api_key"

Available endpoints

• GET /v1/ideas - list ideas with filters (categories, keywords, date range, validation score, sorting)
• GET /v1/ideas/:id - full idea detail
• GET /v1/ideas/:id/posts - source posts for an idea
• GET /v1/categories - all categories with counts

Full documentation with response examples, parameter details, and error codes is available at the API docs page.

Technical details

The API is a standalone Rust service running on our k3s cluster, separate from the main backend. Rate limiting is handled via Redis with a sliding window counter. API keys are SHA-256 hashed at rest - we never store plaintext keys.

The service connects to the same PostgreSQL database as our main app, so data is always up to date. New ideas appear in the API as soon as they're processed by our pipeline.

What you can build with this

Some ideas for what you could do with this data:

• Build a Slack bot that posts new high-scoring business ideas to your team channel
• Create a custom dashboard filtering ideas by your specific niche
• Feed trending ideas into your own newsletter or content pipeline
• Track category trends over time for market research
• Integrate idea discovery into your existing startup tooling

If you build something interesting with the API, we'd love to hear about it.
