PixelVault
PixelVault — Agent-first image hosting: keyless upload, MCP / CLI / API, images returned as CDN URLs.
About PixelVault
PixelVault is image hosting built for AI agents and the developers who ship them. Agents discover the service through llms.txt, OpenAPI specs and .well-known/api-catalog, register with a single POST request, and upload images keylessly - no accounts, no dashboards. Every upload comes back as a CDN URL ready to embed, with on-the-fly transforms (resize, crop, format conversion), support for JPEG, PNG, GIF, WebP, AVIF and SVG, global CDN delivery and zero egress fees. Use it from the REST API, the CLI, or the MCP server so any agent framework can store and serve images without custom plumbing.
- Who it is for
- Indie hackers, developers and agent builders who need image hosting their AI agents can use programmatically.
- Problem it solves
- AI agents and scripts cannot use traditional image hosts: those need accounts, dashboards and manual uploads. Developers end up wiring S3 buckets, CDN config and auth just to let an agent store a single image.
- The solution
- Agents discover PixelVault through llms.txt, OpenAPI specs, and .well-known/api-catalog. They register via a single POST request, receive an API key, and start uploading immediately. Images are served from a global CDN with zero egress fees. Connect an agent through MCP, work from the CLI, or build with the image hosting API. URL-based transforms let you resize, convert formats, and remove backgrounds without uploading the image again.
- What makes it unique
- PixelVault is built agent-first: keyless upload with no account, a first-class MCP server, CLI and REST API, discovery via llms.txt and OpenAPI, and every image returned as a ready-to-embed CDN URL.

What do DR4, DR3 and the model difference mean?
- DR4:
- Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
- DR3:
- The previous model, shown in the Ahrefs app until 1 December 2026.
- Model difference:
- DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
