2 SCVD Evidence Agent
scvd.store is an evidence observatory for agentic commerce — x402 today, cross-protocol by design: independent signed observation of what other people's endpoints, artifacts and payments actually did, with the gaps counted against itself. This agent is the observatory's delegated face: it independently checks x402 endpoints, signed offers and receipts, and signed readiness history, and returns dated, bounded, machine-verifiable evidence. Three read-only tasks, free, no account, no conversation. It never says whether to trust a merchant or which endpoint to use; it is a specialist a planner delegates to when it needs evidence, and every answer states what it does not establish and where to reproduce it. Not an escrow, a guarantor, or a dispute court: those absorb the risk between payment and delivery and need a balance sheet. We observe that gap, sign what we saw, and publish it — including the gaps we count against ourselves.

  • **SEO that executes, not just reports.** [BlogSEO](https://www.blogseo.io) connects your AI assistant to your whole SEO workflow: keywords, content calendar, articles, on-page scoring and publishing to your CMS. ## What you can do - **Keywords**: list tracked keywords with Google Search Console positions, research new ones from seed keywords, refresh metrics, expand topic clusters, find cannibalization and compare rankings between periods. - **Content calendar**: read the schedule, add articles with a brief and a target keyword, reschedule, edit or remove pending articles, get headline suggestions. - **Articles**: read and list articles, update the headline, slug, meta description, cover image and alt text, edit content with AI, then publish or sync to WordPress, Shopify, Webflow, a custom webhook or the hosted blog. - **SEO checks**: on-page SEO score, competitor benchmark and AI improvements for an article or pasted content, plus domain rating, backlink profile and keyword density for any page. - **Multiple websites**: built for agencies and owners running several sites. Pick which websites the assistant can use on the consent screen. ## Example prompts - "Show my keywords ranking between position 5 and 15 with the most impressions, and what to change on each page to reach page 1." - "Schedule an article for next Monday targeting 'cold email deliverability' and brief it to compare Gmail and Outlook filtering." - "Score my latest article and apply the top three fixes." ## Access and safety Sign in with OAuth, no API key to paste.
