# astrasync.shop

> AstraSync's reference agentic-commerce merchant. Real-money digital goods. AI agents only — no human-facing checkout. Eight agentic-commerce protocols + an MCP server.

Identity gateway: **AstraSync verification-gateway 2.4.6** (endpoint ASTRAE-UZ0Osh4meLKZxV16sLmWuw on https://staging.astrasync.ai/api). Tiered catalog model: anonymous callers see RRP + basic fields; verified ASTRA-ids see offers/discounts/promotions; verified ASTRA-ids with shopping.purchase scope can transact.

## Buying as an agent

Eight protocols accepted. Each maps to a single POST endpoint:

- ACP (OpenAI / Stripe ACP): https://astrasync.shop/api/checkout/acp
- AP2 (Google Agent Payments): https://astrasync.shop/api/checkout/ap2
- A2A (Linux Foundation): https://astrasync.shop/api/checkout/a2a
- UCP (Google / Shopify): https://astrasync.shop/api/checkout/ucp
- MPP (Stripe Machine Payments): https://astrasync.shop/api/checkout/mpp
- VI (Mastercard Verifiable Intent): https://astrasync.shop/api/checkout/vi
- Agent Pay (Mastercard): https://astrasync.shop/api/checkout/agent-pay
- TAP (Visa Trusted Agent Protocol): https://astrasync.shop/api/checkout/tap

Checkout requires a verified ASTRA-id reaching accessLevel `standard` (or `read-only` per current policy). Anonymous / unverified callers receive 401 + structured guidance pointing at https://astrasync.ai/register.

## MCP

For platform agents, an MCP server is exposed at https://astrasync.shop/mcp. Three tools: list_products, get_product, start_checkout. Discovery: https://astrasync.shop/.well-known/mcp.json. The hosted Anthropic Skills file at https://astrasync.shop/skill.md is a drop-in primer for Claude chat agents.

Session model: stateless — each JSON-RPC request is independent.
