How to Find Fitness Influencers Programmatically (No Scraping, No API Keys)

#fitness #api #ai #python

I've been building AI agents that do influencer research, and the boring part was always finding the right accounts. Scraping Instagram was either slow, fragile, or got us rate-limited. Paid APIs wanted annual contracts.

Then I found a pay-per-request approach. No account setup, no monthly fees — just pay per search with USDC.

Here's how it works.

The Use Case

I'm building a fitness app that wants to find micro-influencers in the gym/workout niche — specifically women in the US with 10K-100K followers. The old approach: scrape hashtags, filter manually, hope nothing breaks. The new approach: one API call.

The Code

import httpx

response = httpx.get(
    "https://api.socialintel.dev/v1/search",
    params={
        "query": "fitness influencer",
        "country": "United States",
        "gender": "woman",
        "followers_min": 10000,
        "followers_max": 100000,
        "limit": 20
    }
)

# First call returns a free sample to validate data quality
print(response.json())

The first call returns a free sample so you can validate the data quality before paying. Paid calls ($0.10 each) use the x402 protocol — your AI agent handles the payment automatically.

Sample Output

{
  "results": [
    {
      "username": "...",
      "followers": 87400,
      "category": "Fitness & Wellness",
      "gender": "woman",
      "country": "United States",
      "email": "contact@...",
      "is_verified": false
    }
  ]
}

Real accounts, real follower counts, real contact emails where available.

Filters Available

country — "United States", "United Kingdom", "Germany", etc.
gender — "man" or "woman"
followers_min / followers_max — any range
city — specific cities like "Los Angeles" or "New York"
category — fitness, yoga, nutrition, sports, etc.

Why x402 Instead of Traditional API Keys?

The x402 protocol (built by Coinbase) lets AI agents pay for API calls directly — no human in the loop. Your agent discovers the endpoint, sees the price ($0.10), pays in USDC, gets the data. No monthly billing, no rate limit surprises.

For fitness app development: prototype today, scale tomorrow. You only pay for searches you run.

Try It Free First

The free endpoint gives you a preview without payment — useful for testing your filters:
