SEO analysis, SEO toolkit: audit, keywords, social preview

$0.02 per call · failed calls are never charged · no account or API key needed

One call for an on-page SEO analysis of a URL: the SEO audit (title and description lengths, canonical, headings, alt text, structured data, score, issues), the top keywords and two-word phrases with their density, the social preview (OpenGraph, Twitter card), the favicon, and robots.txt access with its sitemaps. Server HTML only. Cheaper than the tools one by one. Use before publishing, for an SEO report or to compare a competitor's page.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/pack/seo-toolkit?url=https%3A%2F%2Fwww.wikipedia.org%2F"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/pack/seo-toolkit?url=https%3A%2F%2Fwww.wikipedia.org%2F&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
