# Get SRR by Collection contract address and Token Id

to get SRR data

<mark style="color:blue;">`GET`</mark> `<base_url>/port/api/v1/collection/{collectionContractAddress}/srr/{tokenId}`

Please replace `<base_url>` as explained [here](/readme/url-per-environment.md).

{% hint style="info" %}
**Recommended: query the subgraph directly**

This endpoint proxies a single SRR record from the [Startrail subgraph](/subgraph/subgraph.md). For most use cases — and especially when you need richer filtering, batching, or low latency — query the subgraph directly. The endpoint does **not** include the metadata JSON; fetch it from the [Startrail IPFS CDN gateway](/subgraph/ipfs-cdn-gateway.md) at `https://cdn.startrail.io/ipfs/<metadataDigest>`.
{% endhint %}

| ----------------------------------------- | ------ | -------------------------------------------------------------------------- |
| tokenId<mark style="color:red;">\*</mark> | string | TokenId of SRR. Example: 59531933                                          |
| collectionContractAddress                 | string | Ethereum address:, for example: 0xb3c438dCe59d2A1b6994E437d879ae00f24F2d34 |

{% tabs %}
{% tab title="200: OK " %}
Single SRR record sourced from the subgraph (without the IPFS-resident `metadata` JSON, `customHistories` or aggregated `transfers`). See [Description of SRR Data](/get-srr-api/description-of-srr-data.md) for the field reference.
{% endtab %}

{% tab title="404: Not Found" %}
The collection/tokenId pair is not present in the subgraph.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.startrail.io/get-srr-api/get-srr-by-token-id.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
