eBay on the pay layer: the 360 agent-readiness check

In short

eBay scores 30 of 100 on Ora's agent-readiness scan, a D, read 14 Nov 2026. The six payment checks did not apply to ebay.com on this read, which is how Ora treats a site it does not read as a shop. A read that got no page back, and an MCP package on npm without a handshake.

On 14 Nov 2026 the public site at ebay.com scored 30 of 100 on Ora's agent-readiness scan, a D, in Ora's E-commerce category. eBay is the global marketplace for new and used goods, selling in more than 190 markets, 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.

The pay layer

Ora did not run the six payment checks against ebay.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 marketplace 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.

The six Payments checks Ora runs, on ebay.com, read 14 Nov 2026. A protocol not found costs nothing, and a check marked does not apply was not run against the site.

The fixes worth most points

Ora attaches an estimate to each failing or partial check: how many points the site would gain by passing it. These are the 5 with the largest estimates for eBay.

Developer portal
Fail, 0 of 5, about 5.1 points to gain. Ora saw: No developer portal found.
Public API/docs linked from homepage
Fail, 0 of 4, about 4 points to gain. Ora saw: No public API or documentation page linked from homepage.

Fail, 0 of 5, about 3.3 points to gain. Ora saw: No OAuth 2.0 or OpenID Connect support detected.

Our read

eBay's read never got past the door, though not because the door was shut: Ora's request for the home page got no page back, the agent user agents could not be tested and robots.txt could not be fetched, so the door, content, policy and structured-data rows are unverified rather than failed, and the Access layer reads 0 of 45. Ora found no commerce signals on a marketplace with more than a billion live listings, so the six payment checks did not apply on this read. What it did find is on the act layer: a first-party MCP package on npm, @ebay/npm-public-api-mcp, credited without a live handshake, and a GraphQL endpoint at api.ebay.com with introspection gated. It found neither an OpenAPI specification nor OAuth discovery, neither a developer portal nor declared scopes, and neither a sitemap nor an llms.txt. The domain ranks fourth for its own name and matched a Wikidata item without a Wikipedia article. A second scan decides whether the 30 is the site or the day.

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.
