Booking.com on the pay layer: the 360 agent-readiness check
Booking.com scores 37 of 100 on Ora's agent-readiness scan, a D, read 14 Nov 2026. The six payment checks did not apply to booking.com on this read, which is how Ora treats a site it does not read as a shop. A notice asking the agent to enable JavaScript, and a robots.txt that is a web page.
On 14 Nov 2026 the public site at booking.com scored 37 of 100 on Ora's agent-readiness scan, a D, in Ora's Travel & Hospitality category. Booking.com is the largest online travel agency in the world by bookings, 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: Keeps agents at arm's length: no MCP server, no OpenAPI spec, and the homepage renders no text without JavaScript.

The pay layer
Ora did not run the six payment checks against booking.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 travel seller 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 x402 payment protocol support detected. 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 MPP (Machine Payments Protocol) support detected. 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 UCP (Universal Commerce Protocol) signals detected. 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 ACP (Agentic Commerce Protocol) signals detected. No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
The other layers, check by check
Every check Ora ran on booking.com, grouped by layer, with the result, the points and what Ora recorded where its wording passes this site's gate.
Discovery: 8.5 of 13
| Check | Result | Points | What Ora saw |
|---|---|---|---|
| ARD discovery | Fail | 0 of 1 | No /.well-known/ard.json, no same-site rel="ard" link, and no legacy /.well-known/ai-catalog.json |
| Developer resource discoverability | Pass | 4 of 4 | Pass, no detail recorded. |
| Brand name discoverability | Partial | 1 of 3 | booking.com ranks #6 for "booking" (searched your brand name alone: no main product term from your homepage qualified) |
| robots.txt AI crawler policy | Partial | 0.5 of 1 | robots.txt answered an HTML page instead of rules. Crawlers find no rules in it and read the whole site, so your AI crawler policy is not stated. Serve a plain-text robots.txt |
| NPM/PyPI SDK package | Fail | 0 of 1 | No NPM or PyPI SDK package found |
| Agent platform configs | Fail | 0 of 1 | Could not locate a public repo containing agent configs or rules. If our probes missed it, AI coding agents likely will too - link the repo from your homepage or docs so it's discoverable. |

| ChatGPT app listed | Pass | 2 of 2 | Pass, no detail recorded. |

| llms.txt exists | Pass | 1 of 1 | Found the llms.txt at https://developers.booking.com/llms.txt. |
| llms.txt formatting | Partial | 1 of 2 | The llms.txt at https://developers.booking.com/llms.txt is well-formatted with markdown links, but at 99,808 characters it exceeds the 30,000-character recommendation for a navigation index. |

Our read
Booking.com opens the door to all four agent user agents and shows them a notice asking them to enable JavaScript: the home page renders zero characters of text without it, so the content row fails and no JSON-LD is read. robots.txt answers with an HTML page instead of rules, so the policy rows cannot be met, and there is no sitemap. Ora read no commerce signals on the largest online travel agency in the world, so the six payment checks did not apply on this read. The act layer is the part that works: developers.booking.com is a real portal with its own llms.txt, an OAuth endpoint sits at login.booking.com, though the API has no machine-verifiable surface, its endpoints do not answer errors as JSON, and Ora found neither an OpenAPI specification nor an MCP server, and no declared scopes. The domain ranks sixth for the word booking. An llms.txt for developers and no home page an agent can read; the template is the fix.
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.
