This skill retrieves upcoming earnings announcements for US stocks using the Financial Modeling Prep (FMP) API. It focuses on companies with significant market capitalization (mid-cap and above, over $2B) that are likely to impact market movements. The skill generates organized markdown reports showing which companies are reporting earnings over the next week, grouped by date and timing (before market open, after market close, or time not announced).
Version history
Key Features:
This skill requires a Financial Modeling Prep API key.
Get Free API Key:
API Key Setup by Environment:
Claude Code (CLI):
export FMP_API_KEY="your-api-key-here"
Claude Desktop: Set environment variable in system or configure MCP server.
Claude Web: API key will be requested during skill execution (stored only for current session).
CRITICAL: Always start by obtaining the accurate current date.
Retrieve the current date and time:
Date Range Calculation:
Current Date: [e.g., November 2, 2025]
Target Week Start: [Current Date + 1 day, e.g., November 3, 2025]
Target Week End: [Current Date + 7 days, e.g., November 9, 2025]
Why This Matters:
Format dates in YYYY-MM-DD for API compatibility.
Before retrieving data, load the comprehensive FMP API guide:
Read: references/fmp_api_guide.md
This guide contains:
Detect API key availability based on environment.
Multi-Environment API Key Detection:
if [ ! -z "$FMP_API_KEY" ]; then
echo "✓ API key found in environment"
API_KEY=$FMP_API_KEY
fi
If environment variable is set, proceed to Step 4.
If environment variable not found, use AskUserQuestion tool:
Question Configuration:
Question: "This skill requires an FMP API key to retrieve earnings data. Do you have an FMP API key?"
Header: "API Key"
Options:
1. "Yes, I'll provide it now" → Proceed to 3.3
2. "No, get free key" → Show instructions (3.2.1)
3. "Skip API, use manual entry" → Jump to Step 8 (fallback mode)
3.2.1 If user chooses "No, get free key":
Provide instructions:
To get a free FMP API key:
1. Visit: https://site.financialmodelingprep.com/developer/docs
2. Click "Get Free API Key" or "Sign Up"
3. Create account (email + password)
4. Receive API key immediately
5. Free tier includes 250 API calls/day (sufficient for daily use)
Once you have your API key, please select "Yes, I'll provide it now" to continue.
If user has API key, request input:
Prompt:
Please paste your FMP API key below:
(Your API key will only be stored for this conversation session and will be forgotten when the session ends. For regular use, consider setting the FMP_API_KEY environment variable.)
Store API key in session variable:
API_KEY = [user_input]
Confirm with user:
✓ API key received and stored for this session.
Security Note:
- API key is stored only in current conversation context
- Not saved to disk or persistent storage
- Will be forgotten when session ends
- Do not share this conversation if it contains your API key
Proceeding with earnings data retrieval...
Use the Python script to fetch earnings data from FMP API.
Script Location:
scripts/fetch_earnings_fmp.py
Execution:
Option A: With Environment Variable (CLI):
python scripts/fetch_earnings_fmp.py 2025-11-03 2025-11-09
Option B: With Session API Key (Desktop/Web):
python scripts/fetch_earnings_fmp.py 2025-11-03 2025-11-09 "${API_KEY}"
Script Workflow (automatic):
Expected Output Format (JSON):
[
{
"symbol": "AAPL",
"companyName": "Apple Inc.",
"date": "2025-11-04",
"timing": "AMC",
"marketCap": 3000000000000,
"marketCapFormatted": "$3.0T",
"sector": "Technology",
"industry": "Consumer Electronics",
"epsEstimated": 1.54,
"revenueEstimated": 123400000000,
"fiscalDateEnding": "2025-09-30",
"exchange": "NASDAQ"
},
...
]
Save to file (recommended for use with report generator):
python scripts/fetch_earnings_fmp.py 2025-11-03 2025-11-09 "${API_KEY}" > earnings_data.json
Or capture to variable:
earnings_data=$(python scripts/fetch_earnings_fmp.py 2025-11-03 2025-11-09 "${API_KEY}")
Error Handling:
If script returns errors:
Once earnings data is retrieved (JSON format), process and organize it:
Load JSON data from script output:
import json
earnings_data = json.loads(earnings_json_string)
Or if saved to file:
with open('earnings_data.json', 'r') as f:
earnings_data = json.load(f)
Confirm data includes required fields:
Group all earnings announcements by date:
Within each date, create three sub-sections:
Data is already sorted by timing from the script, so maintain this order.
Companies are already sorted by market cap descending (script output):
This prioritization ensures the most market-moving companies are listed first.
Compute:
Use the report generation script to create a formatted markdown report from the JSON data.
Script Location:
scripts/generate_report.py
Execution:
Option A: Output to stdout:
python scripts/generate_report.py earnings_data.json
Option B: Save to file:
python scripts/generate_report.py earnings_data.json earnings_calendar_2025-11-02.md
What the script does:
The script automatically handles all formatting including:
