How this service works

Technical details
Endpoint
POSThttps://true402.dev/api/v1/robots-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to verify whether a target website permits automated crawling before attempting to scrape or access it. Particularly useful for compliance-aware web agents that need to respect robots.txt policies. Prefer over manual robots.txt fetching when you want a pay-per-call, machine-native approach with no API key setup.
Side effects
- Invalid or malformed URL returns validation error
- Site unreachable or domain does not exist returns connectivity error
- Site has no robots.txt — response may indicate absence
- Payment failure via HTTP 402 if USDC wallet balance is insufficient
- Timeout if target site is slow to respond
