Carrefour on the pay layer: the 360 agent-readiness check
Carrefour scores 60 of 100 on Ora's agent-readiness scan, a C, read 14 Nov 2026. The six payment checks did not apply to carrefour.com on this read, which is how Ora treats a site it does not read as a shop. A C earned by having almost nothing for the checklist to test.
On 14 Nov 2026 the public site at carrefour.com scored 60 of 100 on Ora's agent-readiness scan, a C. Carrefour is the French grocery group, selling online in its home market and abroad, so this check reads the Payments layer first: the six checks that look for x402, MPP, UCP, ACP and AP2 on the domain, the same protocols this site's matrix tracks row by row. The other layers follow, with every check Ora ran and what it saw. Ora's one-line summary: Carrefour offers strong product discovery and search indexing, but lacks WebMCP support for agent integration.
The score
| Layer | Points | Share | What the layer asks |
|---|---|---|---|
| Discovery | 10 of 11 | 91% | Can agents find and recommend it |
| Access | 13 of 39 | 33% | Can agents read it |
| Usability | 9 of 14 | 64% | Can agents use it |
| Payments | 0 of 0 | none apply | Can agents pay |
| Total | 60 of 100 | 60% | Grade C |
The pay layer
Ora did not run the six payment checks against carrefour.com on this read: it marks them not applicable on a site it does not read as a shop, so the layer has no maximum and costs nothing. A retailer that sells online can still publish any of the five protocols; the matrix says which processors and platforms carry each one. Each protocol links to its matrix row, where the processors and platforms that carry it are dated and sourced.
| Payment check | Result | Points | Matrix row | What Ora saw |
|---|---|---|---|---|
| x402 | Does not apply | 0 of 2 | x402 in the matrix | No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| MPP | Does not apply | 0 of 2 | MPP in the matrix | No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| UCP | Does not apply | 0 of 3 | UCP in the matrix | No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| ACP | Does not apply | 0 of 3 | ACP in the matrix | No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| ACP delegate payment | Does not apply | 0 of 3 | ACP in the matrix | No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| AP2 | Does not apply | 0 of 3 | AP2 in the matrix | No commerce signals detected - agent-payment protocols are optional for non-commerce sites |

Our read
Carrefour's 60 is a C earned by having little to check: the Usability layer has a maximum of 14 and the Access layer 39, because corporate carrefour.com publishes neither an API nor a developer portal, and no MCP server, so the rows that fail elsewhere drop out of the denominator. The door is open to ChatGPT-User, OAI-SearchBot and Claude-User, robots.txt allows the search and training crawlers and the sitemap carries 1,407 entries; the home page gives 780 characters without an H1, with neither JSON-LD nor an llms.txt. Ora read no commerce signals on the corporate domain of Europe's largest food retailer, so the six payment checks did not apply on this read, the shops living on country domains the scan did not visit. The WebMCP estimate of 15.9 points is large only because so few checks apply. The brand search ran on the page title, Welcome at Carrefour, and placed the domain third. The score measures what a site attempts.
Test your own checkout
The scan above is free and needs no account: enter a domain at ora.ai and read the same layers for your own site, with the six payment checks mapped to this matrix on the Ora Payments page. The command below runs the same audit from a terminal and exits with 1 under the score you set, so it can gate a deploy. Why Ora, and its limits.
