Embrace Spans API
The Spans API allows you to query your spans using TraceQL. To get started, take a look at Grafana Integration guide. The API implements the Tempo HTTP API, for more information you can read here.
Prerequisites
- Embrace Spans API Token. This is a different token than the Metrics API token and from the Custom Metrics token. Contact an Embrace onboarding specialist to get this token for your organization. Once you receive the token, you can proceed independently retrieving spans information.
info
If you want to get a feel of the API, you can use the Sandbox token: dc8b04fb11874ee19a6ac1ced98da486
This token will get artificial data for you to test the API and see how it works.
API Endpoints
All the endpoints have the same authentication and authorization method and url. Use the Spans API token provided by an Embrace onboarding specialist to get spans information.
URL:https://api.embrace.io/spans
Authorization
Headers:
Authorization: we are going to use a Bearer token to authorize and authenticate our requests. i.e.:Authorization: Bearer 7bd49186fed24af699cf93069fc64f03.
/search
This endpoint allows you to search for spans based on a TraceQL query. Parameters:
q = (TraceQL query): Url encoded TraceQL query.limit= (integer) Optional. Limit the number of search results. Default is 20start= (unix epoch seconds) Optional. Along withenddefine a time range from which span should be returned.end= (unix epoch seconds) Optional. Along withstart, define a time range from which spans should be returned. Providing both start and end will change the way that Tempo searches. If the parameters are not provided, then it will search the most recent spans.spss= (integer) Optional. Limit the number of spans on the results. The default value is 3. To speed up the search, you can filter using thespan.emb.app_idattribute.
Search for spans using TraceQL

Search a specific span using the span id
To search for a specific span you need to add in the query parameter the span id you want to search for
using the span.emb.span_id attribute.
curl -G 'https://api.embrace.io/spans/api/search' \
--header 'Authorization: Bearer TOKEN' \
--data-urlencode 'q={span.emb.span_id="1f8ecc91e9c89cc4" && span.emb.app_id="SpanA"}' | jq

/traces
To get a specific trace you can use the /traces endpoint. You need to provide the trace id in the url:
curl 'https://api.embrace.io/spans/api/traces/4d67df900d474c740eb302939b596c3d' \
