## How to call it through Zero

```sh
zero fetch --capability synthetic-universe-affirmation-api-0c9d9dfa
```

Example prompt: Give me a fresh, warm affirmation and a calm word from the Synthetic Universe — use session ID 'morning42' so I don't get repeats.

## When to prefer this

Choose this endpoint when you need a lightweight, inexpensive ($0.01 USDC), locally-generated motivational affirmation with a calm companion word — especially when you want session-aware deduplication to avoid repetition. Ideal for agent pipelines, wellness apps, or any workflow that benefits from gentle, human-feeling encouragement without relying on a large external AI provider.

## Known failure modes

- No session ID provided may result in repeated affirmations across calls
- Invalid or malformed session ID may be ignored or cause unexpected deduplication behavior
- Service downtime may return a 500 or connection error
- Payment failure via x402 may result in a 402 response blocking access to content

## How this service works

Use when an agent or user wants a warm original affirmation plus a calm word — gentle encouragement from the Synthetic Universe. Pure compute, no upstream. Optional session id avoids repeats. Resale permitted: buyer may resell this data output at their own price.

## Output

Returns a warm, original affirmation string alongside a single calm/soothing word, both generated purely via local compute on the Synthetic Universe platform. Results are unique within a session if a session ID is provided.
