# AssetCheck x402 API

AssetCheck is deterministic game asset quality control for autonomous agents and release pipelines. Use it for sprite QC, texture validation, asset pack preflight, release validation, duplicate asset detection, file collision detection, game asset packaging, and generated asset QC.

## Paid endpoints

- POST https://assetcheck-agent-economy.miguel-117.workers.dev/v1/check/manifest — $0.001 USDC via x402 — Deterministic game asset QC for sprite validation, texture validation, asset pack preflight, release validation, duplicate asset detection, file collision detection, game asset packaging, and generated asset QC before an agent ships a build. Submit a complete manifest for PASS/WARN/FAIL release QC.
- POST https://assetcheck-agent-economy.miguel-117.workers.dev/v1/check/asset-pack — $0.001 USDC via x402 — Deterministic game asset QC for sprite validation, texture validation, asset pack preflight, release validation, duplicate asset detection, file collision detection, game asset packaging, and generated asset QC before an agent ships a build. Preflight an asset pack before packaging or publishing.
- POST https://assetcheck-agent-economy.miguel-117.workers.dev/v1/check/duplicates — $0.001 USDC via x402 — Deterministic game asset QC for sprite validation, texture validation, asset pack preflight, release validation, duplicate asset detection, file collision detection, game asset packaging, and generated asset QC before an agent ships a build. Detect duplicate assets from caller-provided content hashes.
- POST https://assetcheck-agent-economy.miguel-117.workers.dev/v1/check/path-collisions — $0.001 USDC via x402 — Deterministic game asset QC for sprite validation, texture validation, asset pack preflight, release validation, duplicate asset detection, file collision detection, game asset packaging, and generated asset QC before an agent ships a build. Detect case-insensitive file collisions and unsafe paths.
- POST https://assetcheck-agent-economy.miguel-117.workers.dev/v1/check/sprite-metadata — $0.001 USDC via x402 — Deterministic game asset QC for sprite validation, texture validation, asset pack preflight, release validation, duplicate asset detection, file collision detection, game asset packaging, and generated asset QC before an agent ships a build. Validate sprite dimensions, sheets, grids, and raster metadata.

All paid endpoints accept JSON with a required files array. Each file may include path, size, width, height, hash, and decodeError. Optional options include tileWidth, tileHeight, maxDimension, and requirePowerOfTwo. Responses are assetcheck.agent.receipt.v1 receipts with PASS, WARN, or FAIL status.
