How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
Returns a JSON object with a status field (e.g. 'ready') indicating whether the specified URL and path are permitted by the site's robots.txt rules, enabling agents to make go/no-go crawl decisions before fetching content.
Example use cases
Pre-scrape compliance check
“I want to scrape product prices from https://shop.example.com/products — can you first check if robots.txt allows my bot to access that path?”
RAG pipeline ingestion gate
“Before ingesting https://docs.acme.com/api/reference into our RAG system, verify that the robots.txt on that site permits crawling that URL.”
Multi-site crawler permission audit
“Check if https://news.site.com/articles is accessible to a generic crawler according to their robots.txt so I know whether to include it in my data pipeline.”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/web/robots-check?utm_source=zero.xyzWhen to prefer
Use this endpoint before any web scraping, crawling, or RAG ingestion workflow to confirm you have robots.txt permission for a target URL. Prefer this over manual robots.txt parsing when you need a machine-payable, programmatic compliance check integrated into an automated agent pipeline. Especially valuable when building responsible scraping agents that must respect site policies before extracting content.
Side effects
- URL is malformed or not a valid URI — input validation error
- Target site is unreachable or robots.txt cannot be fetched — network or timeout error
- Site has no robots.txt, which may be interpreted as open access
- Path not specified and defaults may not match intended crawl target
- User agent not specified, defaulting to generic crawler rules that may differ from intended bot identity
