Summary of the Secure SNA endpoints. Full request and response schemas live in the API Reference.

| Method | Path                                                            | Purpose                                                       |
| ------ | --------------------------------------------------------------- | ------------------------------------------------------------- |
| `POST` | `/v1/number-verification/secure-sna-checks`                     | Create a check                                                |
| `GET`  | `/v1/number-verification/secure-sna-checks/{check_id}`          | Get a check                                                   |
| `GET`  | `/v1/number-verification/secure-sna-checks`                     | List checks (paginated; supports RSQL filtering)              |
| `POST` | `/v1/number-verification/secure-sna-checks/{check_id}/code`     | Complete a check by submitting the verification code          |
| `GET`  | `/v1/number-verification/secure-sna-checks/{check_id}/redirect` | Device-facing verification URL (the `url` returned on create) |

## Common requirements

All endpoints require:

* HTTPS.
* An OAuth2 Bearer token with the `secure_sna` scope on the `Authorization` header.
* The `{data_residency}` host prefix matching your workspace region (`eu.api.idlayr.com` or `us.api.idlayr.com`). See [Data residency](/get-started/concepts/data-residency.md).

## Common response headers

* `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` — see Rate limits in the API Reference.
* On `429`, a `Retry-After` header indicates seconds before retrying.

## Common error responses

`400` invalid phone number, `400` country not supported, `401` unauthorized, `404` check not found, `405` method not allowed (POST for code redemption attempted before the device redirect was performed), `409` IP/MSISDN mismatch, `412` not a mobile IP, `429` rate limit reached. Full error taxonomy on the [Error codes](/products/number-verification/secure-sna/error-codes.md) page.

* The [Integration backend page](/products/number-verification/secure-sna/integration/backend.md) walks through creating and completing a check with cURL.
* The full API Reference will carry the complete request/response schemas for each endpoint (linked from here once published).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.idlayr.com/products/number-verification/secure-sna/endpoints.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
