Logfire (Pydantic)

GigaFlow queries Logfire's FusionFire Query API. Bundled transform — gigaflow/transforms/logfire.yml handles pydantic-ai/Logfire spans.

Prerequisites

• A Logfire read token (Logfire → project → Settings → Read tokens).
• Your project's API base, e.g. https://logfire-us.pydantic.dev/<org>/<project> (the org segment is your Logfire org/username slug).

Connect (API)

PID=$(curl -s -X POST "$GIGAFLOW_BACKEND_URL/projects/" -H "Authorization: Bearer $GIGAFLOW_API_KEY" \
  -H 'Content-Type: application/json' -d '{"name":"my-logfire-project"}' | python3 -c 'import sys,json;print(json.load(sys.stdin)["project_id"])')

curl -X PUT "$GIGAFLOW_BACKEND_URL/projects/$PID/transform" -H "Authorization: Bearer $GIGAFLOW_API_KEY" \
  -H 'Content-Type: text/plain' --data-binary @gigaflow/transforms/logfire.yml

curl -X POST "$GIGAFLOW_BACKEND_URL/datasources/" -H "Authorization: Bearer $GIGAFLOW_API_KEY" \
  -H 'Content-Type: application/json' -d "{
    \"project_id\": \"$PID\",
    \"name\": \"my-logfire\",
    \"source_type\": \"logfire\",
    \"connection_url\": \"https://logfire-us.pydantic.dev/<org>/<project>\",
    \"api_key\": \"<logfire read token>\"
  }"

Optional: set service_name_filter on the datasource to restrict sync to one service (Logfire is the only source that honours it).

Run

gigaflow sync
gigaflow compute "SELECT trace_id FROM trace_metrics WHERE run_id IS NULL"
gigaflow inspect <trace_id>
