# WithZero CDN Large Static Site Deploy (Manifest-Based) > WithZero CDN Large Static Site Deploy (Manifest-Based) is a paid API for AI agents from agents.withzero.xyz, paid per call via MPP, price unknown, status unknown (last checked 2026-10-16). Deploys a large static site (up to 5,000 files / 500 MiB) using a manifest-diffing workflow: submit file paths with sizes and MD5 hashes, receive upload URLs only for new/changed files, PUT the bytes, then commit the deploy. ## Facts - Endpoint: POST https://agents.withzero.xyz/api/v1/cdn/deploys?utm_source=zero.xyz - Price: price unknown - Payment: MPP - Status: unknown - Last checked: 2026-10-16 - Activations on Zero: 0 - Provider: agents.withzero.xyz - Website: https://agents.withzero.xyz - Canonical page: https://www.zero.xyz/c/agents-withzero-xyz-withzero-cdn-large-static-site-deploy-manifest-ecc9d833 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_oifiWSuEV5GWB2jNWTKO8 Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agents-withzero-xyz-withzero-cdn-large-static-site-deploy-manifest-ecc9d833 -d '' ``` Example prompt: Deploy my static site build to WithZero — I have about 2,000 files totalling 180 MiB; send the manifest of paths, sizes, and MD5s, get upload URLs for anything new or changed, push those files, and commit the deploy under the slug 'my-docs-site'. ## When to prefer this Choose this endpoint when deploying static sites with a large number of files (hundreds to thousands) where incremental redeploys matter — the manifest-diffing approach ensures only changed files are uploaded, saving bandwidth and time. Prefer this over simpler single-file or small-site upload endpoints when your build output exceeds a few dozen files or when you need efficient CI/CD-style redeployment without re-uploading unchanged assets. ## Known failure modes - Manifest exceeds 5,000 files or 500 MiB limit — request rejected with 400 - MD5 mismatch between manifest and uploaded bytes — commit fails with validation error - Upload URL expires before PUT completes — requires re-fetching upload URLs - Missing or malformed file paths in manifest — 400 bad request - Payment not attached or insufficient — 402 response before processing begins - Slug conflict with an existing site owned by another identity — 403 or 409 ## How this service works Deploy a large static site (up to 5,000 files / 500 MiB) by manifest: send every path with its size and MD5, get upload URLs for only the files not already stored, PUT the bytes, then commit. Redeploys upload only what changed. ## Output Returns a list of presigned upload URLs for only the files not already stored on the CDN (based on MD5 diffing), a deploy ID to reference during the PUT phase and final commit, and after committing, a confirmation of the live deploy with its CDN URL and deploy status. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "slug", "files" ], "properties": { "slug": { "type": "string", "maxLength": 512, "minLength": 1, "description": "The site to deploy, served at /// — the same slug as a kind:site upload.
