# Checkout.com: the 360 agent-readiness check

Checkout.com scores 73 of 100 on Ora's agent-readiness scan, a B, read 9 November 2026. Of the five surfaces an agent acts on, Ora found 2: a public API, OAuth. A home page worth copying, in front of an API with no specification.

On 9 November 2026 the public site at checkout.com scored 73 of 100 on [Ora's](https://ora.ai/?utm_source=agentmcpdirectory.com&utm_medium=referral&utm_campaign=check) agent-readiness scan, a B, in Ora's Payments & Fintech category. Ora probes a site the way an agent would: it requests pages with the agents' own user agents, reads robots.txt, looks for the files agents read, and tries the API, MCP and payment surfaces. This check reads the act layer first, because that is what the directory records, then the door, what an agent can read, and whether the company is found and recommended. Ora's one-line summary: Checkout.com offers strong developer SDKs and documentation discovery, but needs an OpenAPI specification for agent integration.

## The score

| Layer | Asks | Points | Share |
| --- | --- | --- | --- |
| Usability | Can agents use it | 39 of 63 | 62% |
| Access | Can agents read it | 47 of 61 | 77% |
| Discovery | Can agents find and recommend it | 14 of 16 | 88% |
| Payments | Can agents pay | 0 of 0 | none apply |
| Total | Grade B | 73 of 100 | 73% |

## What an agent can do

The surfaces an agent acts on: an API it can find and call, an MCP server, an agent card, OAuth metadata, a command line. This is the layer the directory records, so it comes first. 2 checks in this group do not apply to this site and are left out.

In the directory, Checkout.com sign-in required, tools not seen, not counted; the connector run of 4 November 2026 is on [the entry page](https://agentmcpdirectory.com/directory/checkout-com/). Ora's MCP server check for the same domain reads partial; the two look for different things, the directory for a server that answers a handshake and lists tools, Ora for a server it can find from the site.

## Payments

The agent payment protocols Ora probes for. A site that sells nothing has nothing here, and Ora scores the layer out of zero when none applies.

## 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 Checkout.com, with what Ora observed. The wording of each fix is Ora's; [the 28 checks it runs on an MCP server](https://agentmcpdirectory.com/mcp-checks/) are listed with their layer and tier.

-   OpenAPI spec published: fail, 0 of 7, about 3.8 points to gain. Ora saw: No OpenAPI/Swagger specification found
-   Scoped permissions: fail, 0 of 5, about 3.5 points to gain. Ora saw: No declared OAuth scopes, security schemes, or scoped-permission documentation found
-   WebMCP support: fail, 0 of 5, about 3.5 points to gain. Ora saw: No WebMCP support detected - no document.modelContext / navigator.modelContext usage found
-   JSON error responses: fail, 0 of 4, about 2.8 points to gain. Ora saw: API does not return JSON error responses (or no API detected)
-   CLI tool available: fail, 0 of 3, about 2.1 points to gain. Ora saw: No CLI tool found

## Our read

Checkout.com, the payment processor and not the checkout page of a shop, has a home page worth copying and an act layer worth finishing. The page gives 10,450 characters at a 7.2 percent text ratio with one H1, twelve H2s and twenty-one H3s under a complete Organization block, the site returns markdown when an agent asks for it and checkout.com serves an llms.txt. The MCP server at support.checkout.com/mcp answers and requires authentication, OAuth authorization server metadata sits beside it at /mcp/oauth, the REST documentation scores 7 of 7 and SDKs are in npm, Go and rubygems. Ora found no OpenAPI specification and no declared scopes, about 7 points, endpoints that do not answer errors as JSON, and no CLI. The brand search was run on a common word and placed the domain third. A processor whose customers integrate it by API should publish the file that describes the API.

## Test your own surfaces

The scan above is free and needs no account: enter a domain at [ora.ai](https://ora.ai/?utm_source=agentmcpdirectory.com&utm_medium=referral&utm_campaign=check) and read the same four layers for your own site. For an MCP server, Ora scans the server URL itself and runs 28 of its 132 public checks on it, which is why it is the check this directory recommends; [the reasons, the limits and the alternatives](https://agentmcpdirectory.com/test-your-mcp-server/) are on their own 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.

```bash
npx ax@0.10 audit https://example.com --min-score 70
