Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object confirming whether the supplied changefreq string is a recognized sitemap standard value, the original changefreq string, an overall pass/fail status, and an evidence block including whether any data was retained (always false), a SHA-256 hash of the input, and the number of external calls made (always zero).
Example use cases
SEO audit of sitemap frequency tags
“I'm auditing our site's sitemap and want to make sure every changefreq value we're using — like 'weekly' and 'always' — is actually recognized as a valid token. Can you validate them?”
Sitemap generator correctness check
“Our sitemap generator outputs 'bimonthly' as a changefreq — can you confirm whether that's a recognized value or if we need to fix it?”
Pre-submission sitemap validation
“Before I submit my sitemap to Google Search Console, can you verify that the changefreq value 'daily' is a standard, recognized directive?”
