Two paths depending on your setup: Vertex AI Extensions for Gemini model integration, or Vertex AI Agent Builder for conversational agents.

Option A — Vertex AI Extensions

1. Upload the OpenAPI spec to GCS

curl -o dpx-openapi.yaml \
  https://raw.githubusercontent.com/untitledfinancial/dpx-integrations/main/amazon-bedrock/openapi-bedrock.yaml

gsutil cp dpx-openapi.yaml gs://YOUR_BUCKET/dpx-openapi.yaml

2. Deploy the extension

gcloud ai extensions create \
  --display-name="DPX Protocol" \
  --description="DPX settlement rail — oracle, quotes, ESG, rail health" \
  --manifest-name=dpx_protocol \
  --open-api-gcs-uri=gs://YOUR_BUCKET/dpx-openapi.yaml \
  --project=YOUR_PROJECT \
  --region=us-central1

Or import manually: Vertex AI Studio → Extensions → Create → Import OpenAPI spec from GCS

Option B — Vertex AI Agent Builder

1. Agent Builder → Create Agent → Conversational agent
2. Tools → Create Tool → OpenAPI
3. Paste the live spec URL: https://api.untitledfinancial.com/openapi.json
