FlyPython lets your agent extract structured web data and react when meaningful fields change: prices, stock, jobs, headlines, rankings, docs, and more.
No browser farms. No polling loops. Just Python, structured data, and signed webhook events.
{
"event": "page.changed",
"url": "https://example.com/product",
"change_type": "price_drop",
"confidence": 0.97,
"diff": {
"price": { "before": 129.00, "after": 99.00 },
"stock": { "before": "in_stock", "after": "in_stock" }
},
"summary": "Price dropped 23%. Stock unchanged."
}Not just “the page changed.”
“Price dropped 23%. Stock unchanged.”
Field-level structured diffs, classified and delivered as webhook events.

Extract structured data from a URL
JSON schema for structured extraction. Leave empty for auto-detection.
How It Works
FlyPython handles the web-reading loop so your agents and automations can work with stable events instead of brittle page checks.
Give FlyPython a URL and a schema. It returns typed JSON, markdown, and page metadata your agent can use immediately.
Run checks hourly, daily, or on your own cadence. Dynamic noise like timestamps, tokens, ads, and tracking IDs is filtered before diffing.
When a meaningful field changes, FlyPython sends a signed webhook with before/after values, confidence, and a short summary.
Each event includes the changed fields, before/after values, a confidence score, and a human-readable summary. Delivery is signed, retried, and logged.

url="https://example.com/product",
schema={"price": "number", "stock": "string"},
webhook="https://myagent.com/events",
schedule="0 */6 * * *",
)
