How this service works
Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
Output
A JSON object containing a count of URLs checked, a results array with one entry per URL (ok, url, changed boolean, first_seen boolean, current_hash, previous_hash), and the price in USD charged for the call.
Example use cases
Track competitor pricing page updates
“Watch these three competitor pricing pages for me — https://rivalA.com/pricing, https://rivalB.com/pricing, https://rivalC.com/pricing — and let me know which ones have changed content since the last check.”
Monitor docs site for new releases
“Check all these documentation URLs at once and tell me which ones have been updated or are appearing for the first time: https://docs.mylib.io/changelog, https://docs.mylib.io/api-reference, https://docs.mylib.io/migration-guide.”
Verify regulatory page stability
“I need to confirm that none of these compliance and legal pages have been quietly modified — can you batch-check https://regulator.gov/rules/section-12, https://regulator.gov/notices/2024, and https://regulator.gov/faq for any content changes?”
Technical details
Endpoint
GEThttps://scanpay-edge.alextaghiashvili.workers.dev/api/v1/urlwatch-batch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check multiple URLs for content changes in a single paid call rather than polling each individually. It is ideal for agent workflows that periodically monitor a fixed set of pages (pricing, docs, regulatory notices) and need a hash-based diff signal without storing state themselves. Prefer it over single-URL watchers when you have 2+ URLs to check simultaneously and want to minimize per-call costs.
Side effects
- Invalid or unreachable URL returns ok:false for that entry
- Missing required 'urls' query parameter causes a 400-level error
- Payment not settled via x402 returns 402 Payment Required
- Rate limits or Cloudflare Worker timeouts may cause partial results
- Very large URL batches may exceed request limits
