R25 EA

[cl-mayowa]

Closes #OPDATA-5148

Description

This EA exposes nav endpoint that fetches latest NAV via R25’s REST API and returns a single numeric result with timestamps.

......

Changes

• Added nav endpoint and transport for R25 endpoint
• Checked for response status failure
• Added authentication via API key
• Added tests to verify implementation

Steps to Test

1. Export api key and secret

export API_KEY=<api_key>
export API_SECRET=<api_secret>

2. Start endpoint locally

cd packages/sources/r25
 yarn build && yarn start

3. Test nav endpoint

curl --location 'http://localhost:8080' \
--header 'Content-Type: application/json' \
--data '{
    "data": {
        "endpoint": "nav",
        "chainType": "polygon",
        "tokenName": "rcusdp"
    }
}'

expected response

{
    "result": 1.0176661592,
    "data": {
        "result": 1.0176661592
    },
    "timestamps": {
        "providerDataRequestedUnixMs": 1764374203131,
        "providerDataReceivedUnixMs": 1764374204545,
        "providerIndicatedTimeUnixMs": 1764313200000
    },
    "statusCode": 200,
    "meta": {
        "adapterName": "R25",
        "metrics": {
            "feedId": "{\"chainType\":\"polygon\",\"tokenName\":\"rcusdp\"}"
        }
    }
}

4. run unit and integration tests

Quality Assurance

• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant infra-k8s configuration file.
• If a new adapter was made, or an existing one was modified so that its environment variables have changed, update the relevant adapter-secrets configuration file.
• If a new adapter was made, or a new endpoint was added, update the test-payload.json file with relevant requests.
• The branch naming follows git flow (feature/x, chore/x, release/x, hotfix/x, fix/x) or is created from Jira.
• This is related to a maximum of one Jira story or GitHub issue.
• Types are safe (avoid TypeScript/TSLint features like any and disable, instead use more specific types).
• All code changes have 100% unit and integration test coverage. If testing is not applicable or too difficult to justify doing, the reasoning should be documented explicitly in the PR.
