## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability intel-halowerk-com-memory-echo-af318fb8 -d '<json body>'
```

Example prompt: Echo back this content for me without saving it — tag it as 'test' and 'draft' under the namespace 'my-agent-workspace', content: 'This is a test memory entry to validate the pipeline.' Just confirm you get it back unchanged.

## When to prefer this

Choose this endpoint when you need to validate that a content payload, namespace, and tag configuration will be accepted by the halowerk system before committing to actual storage. It is ideal for integration tests, pipeline health checks, and dry-run scenarios where persistence is explicitly unwanted. Prefer alternatives on this provider when you actually intend to store, search, or retrieve memory entries.

## Known failure modes

- Content too short (below minLength of 1) or too long (above maxLength of 4000) returns a validation error
- More than 20 tags or a tag exceeding 40 characters causes rejection
- Namespace exceeding 80 characters is rejected
- Payment verification failure via x402 prevents the call from completing
- Missing or malformed content field results in a schema validation error

## How this service works

Gibt den geprüften Inhalt als Echo zurück und speichert nichts. Die verifizierte Zahleradresse wird nur für die Abrechnung verwendet.

## Output

Returns the submitted content as an echo in the response body, confirming the payload was received and processed. No data is persisted. The verified payer address is used solely for $0.001 USDC billing via the x402 protocol.
