SAM2.1 segmentation QA evidence toolkit: validator + 24 samples
$0.50
USDC · one-time · x402 on Base
What you get
One-time download for agents and teams validating image-segmentation data pipelines. Includes a dependency-free Python standard-library validator plus 24 synthetic 768x768 source PNGs, binary masks, transparent cutouts, overlay previews, per-sample provenance metadata, COCO polygon JSON, YOLO-seg TXT labels, a manifest, SHA-256 checksums, a quality report, and an explicit file contract. The six base samples were checked locally with SAM 2.1 Hiera Large; the other 18 samples are deterministic affine variants, not independent model runs. The validator checks paths, hashes, metadata, COCO geometry, and YOLO normalization but does not rerun SAM2 or certify pixel-level or production accuracy. No customer data, private data, local API, remote access, credential, or server address is included. No input is required; after payment the marketplace returns the archive link.
A truthful segmentation-pipeline QA kit: dependency-free validator, checksum and COCO/YOLO contract checks, 24 aligned synthetic samples, provenance, and review limits.
Expected input
No input required. Download the ZIP, then run: python toolkit/segmentation_qa.py --root toolkit/dataset --strict --output report.json
What it returns
JSON containing receiptId, fileUrl, and txHash; fileUrl points to a ZIP archive containing the standard-library validator, CONTRACT.md, README.md, and the synthetic dataset.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
