def av_get(function, **params):
    if not API_KEY:

| datatype | json / csv | Default: json |

| interval | 1min, 5min, 15min, 30min, 60min, daily, weekly, monthly | Depends on endpoint |

Rate Limits

• Free tier: 25 requests/day (as of 2026)
• Premium plans: higher limits, real-time data, intraday access
• Quota or entitlement messages may arrive in JSON even with HTTP 200; check Note and Information as well as HTTP status.
• A short delay cannot satisfy a daily quota. Cache results, track the account request budget, and stop when exhausted. Verify current limits and endpoint entitlements in [official support](https://www.alphavantage.co/support/) and [API documentation](https://www.alphavantage.co/documentation/).

Error Handling

data = av_get("GLOBAL_QUOTE", symbol="AAPL")

# Check for API errors
if "Error Message" in data:
    raise ValueError(f"API Error: {data['Error Message']}")
if "Note" in data:
    print(f"Rate limit warning: {data['Note']}")
if "Information" in data:
    print(f"API info: {data['Information']}")

When to Use

Use this skill when tackling tasks related to its primary domain or functionality as described above.

Limitations

• Quotes may be end-of-day or delayed depending on entitlement. Report timestamps and adjustment basis; market-data retrieval is not investment advice. API responses and empty reports need schema checks before indexing.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
