Prerequisites

The user must set the environment variable ONLYFANSAPI_API_KEY with their API key from https://app.onlyfansapi.com/api-keys.

If the key is not set, remind the user:

Export your OnlyFansAPI key:
  export ONLYFANSAPI_API_KEY="your_api_key_here"

API Basics

• Base URL: https://app.onlyfansapi.com
• Auth header: Authorization: Bearer $ONLYFANSAPI_API_KEY
• All dates use URL-encoded format: YYYY-MM-DD HH:MM:SS
• If not specific time is specified use start of day or end of day (for date range ending date)
• Pagination: use limit and offset query params. Check hasMore or _pagination.next_page in responses.
• Whenever possible use User-Agent with value: OnlyFansAPI-Skill
• Try your best to infer schema from the example response of the endpoint. Eg "data.total.total" for earnings scalar value from endpoint.

Workflows

1. Get revenue of all models for the past N days

Steps:

1. List all connected accounts:

   curl -s -H "Authorization: Bearer $ONLYFANSAPI_API_KEY" \
     "https://app.onlyfansapi.com/api/accounts" | jq .
   

   Each account object has "id" (e.g. "acct_xxx"), "onlyfans_username", and "display_name".

2. For each account, get earnings:

   START=$(date -u -v-7d '+%Y-%m-%d+00%%3A00%%3A00')  # macOS
   # Linux: START=$(date -u -d '7 days ago' '+%Y-%m-%d+00%%3A00%%3A00')
   END=$(date -u '+%Y-%m-%d+23%%3A59%%3A59')
   
   curl -s -H "Authorization: Bearer $ONLYFANSAPI_API_KEY" \
     "https://app.onlyfansapi.com/api/{account_id}/statistics/statements/earnings?start_date=$START&end_date=$END&type=total" | jq .
   

   Response fields:

   • data.total — net earnings
   • data.gross — gross earnings
   • data.chartAmount — daily earnings breakdown array
   • data.delta — percentage change vs. prior period

3. Summarize: Present a table of each model's display name, username, net revenue, and gross revenue. Sum the totals.

2. Which model is performing the best

Use the same workflow as above. Rank models by data.total (net earnings) descending. The model with the highest value is the best performer.

Optionally also pull the statistics overview for richer context:

curl -s -H "Authorization: Bearer $ONLYFANSAPI_API_KEY" \
  "https://app.onlyfansapi.com/api/{account_id}/statistics/overview?start_date=$START&end_date=$END" | jq .

This adds subscriber counts, visitor stats, post/message earnings breakdown.

3. Which Free Trial Link has the highest conversion rate (subscribers → spenders)

1. List free trial links:

   curl -s -H "Authorization: Bearer $ONLYFANSAPI_API_KEY" \
     "https://app.onlyfansapi.com/api/{account_id}/trial-links?limit=100&offset=0&sort=desc&field=subscribe_counts&synchronous=true" | jq .
   

   Key response fields per link:

   • id, trialLinkName, url
   • claimCounts — total subscribers who claimed the trial
   • clicksCounts — total clicks
   • revenue.total — total revenue from this link
   • revenue.spendersCount — number of subscribers who spent money
   • revenue.revenuePerSubscriber — average revenue per subscriber

2. Calculate conversion rate:

   conversion_rate = spendersCount / claimCounts
   

   Rank links by conversion rate descending.

3. Present results as a table: link name, claims, spenders, conversion rate, total revenue.

4. Which Tracking Link has the highest conversion rate

1. List tracking links:

   curl -s -H "Authorization: Bearer $ONLYFANSAPI_API_KEY" \
     "https://app.onlyfansapi.com/api/{account_id}/tracking-links?limit=100&offset=0&sort=desc&sortby=claims&synchronous=true" | jq .
   

   Key response fields per link:

   • id, campaignName, campaignUrl
   • subscribersCount — total subscribers from this link
   • clicksCount — total clicks
   • revenue.total — total revenue
   • revenue.spendersCount — subscribers who spent
   • revenue.revenuePerSubscriber — avg revenue per subscriber
   • revenue.revenuePerClick — avg revenue per click

2. Calculate conversion rate:

   conversion_rate = revenue.spendersCount / subscribersCount
   

3. Present results as a table: campaign name, subscribers, spenders, conversion rate, total revenue, revenue per subscriber.

5. Which Free Trial / Tracking Link made the most money

Use the same listing endpoints above. Sort by revenue.total descending. Present the top links with their name, type (trial vs. tracking), total revenue, and subscriber/spender counts.

Multi-Account (Agency) Queries

For agency-level queries that span all models, always:

1. First fetch all accounts via GET /api/accounts
2. Loop through each account and gather the relevant data
3. Aggregate and present combined results with per-model breakdowns

Earnings Type Filters

When querying GET /api/{account}/statistics/statements/earnings, the type parameter filters by category:

• total — all earnings combined
• subscribes — subscription revenue
• tips — tips received
• post — paid post revenue
• messages — paid message revenue
• stream — stream revenue

When In Doubt

If you are unsure about an endpoint, parameter, response format, or how to accomplish a specific task with the OnlyFans API:

1. First, consult the LLM-friendly documentation:

   curl -s "https://docs.onlyfansapi.com/llms-full.txt" | head -n 500
   

   This contains the complete API documentation in a format optimized for AI consumption.

2. Browse the API Reference: https://docs.onlyfansapi.com/api-reference

   • Over 100 endpoints covering most OnlyFans functionality
   • Organized by category: Account, Chats, Messages, Fans, Media, Payouts, Posts, Statistics, Webhooks, and more

3. Key API endpoint categories available:

   • Chats & Messages: List chats, send messages, send mass messages, PPV support

Error Handling

• If ONLYFANSAPI_API_KEY is not set, stop and ask the user to configure it.
• If an API call returns a non-200 status, show the error message and HTTP status code.
• If _meta._rate_limits.remaining_minute or remaining_day is 0, warn the user about rate limits.
• If an account has "is_authenticated": false, note that the account needs re-authentication.

Output Formatting

• Always present data in markdown tables for readability.
• Include currency values formatted to 2 decimal places.
• When showing percentages (conversion rates, deltas), format as XX.X%.
• For multi-model summaries, include a Total row at the bottom.
