| Tool | Description | Behaviour |
|---|---|---|
| extract_data | Extract structured data from a web page, returned as JSON matching a JSON Schema you supply, via Backfill Extract. The service fetches the URL (a plain fetch first, with escalation when the plain fetch returns a bot wall or a JavaScript shell) and extracts the data described by the schema. Extraction is always a paid call (x402, USDC on Base: $0.15 fresh, $0.05 for a cached result), so a call over MCP returns an error directing you to the paid HTTP API at POST https://backfill.top/v1/extract; payment is never attempted over MCP. | Not declared |
| fetch_page | Fetch a web page and return its readable content as clean markdown, via Backfill Fetch. The service fetches the URL (a plain fetch first, with escalation when the plain fetch returns a bot wall or a JavaScript shell) and extracts the content. Calls are answered free when the fetch is free — a plain fetch inside the daily allowance, or a cache hit inside the free cache allowance. When serving the page would require payment (x402, USDC on Base), the call returns an error directing you to the paid HTTP API at POST https://backfill.top/v1/fetch; payment is never attempted over MCP. | Not declared |
