Prerequisites: You need an Allium API key. Get one from app.allium.so/settings/api-keys.
Setup
X-API-Key header for authentication against the base URL https://api.allium.so/api/v1/beam.
Filter USDC transfers on Base
Create the pipeline config
Create a pipeline that streams ERC20 transfers on Base, filtered by token address using a Redis set filter, and outputs to a managed Kafka topic.The response returns the full
BeamConfig with a generated id.Get the transform UID
Fetch the config to extract the auto-generated transform UID — you’ll need it to manage filter values.
Add filter values
Add the USDC contract address on Base. Use lowercase — values are normalized in the system.Expected:
{ "added": 1 }Check deployment health
healthy_workers should match total_workers. If workers are still starting, wait a few seconds and retry.What’s next
- Update your pipeline — modify the config with
PUT /api/v1/beam/{config_id}, then redeploy. No need to teardown first. - Monitor metrics — use
GET /api/v1/beam/{config_id}/deploy/metrics?time_range=1h&aggregated=truefor a throughput summary. - Add more filter values — post additional addresses to the filter values endpoint at any time (no redeploy needed).
