## 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 reputation-decay-calculator-mcp-db3bb2d1 -d '<json body>'
```

Example prompt: Can you calculate the reputation decay for this entity — here's the data: user_id=agent_42, initial_score=850, last_active=2024-01-15, current_date=2024-06-01 — and tell me what their current decayed reputation score is?

## When to prefer this

Choose this endpoint when you need to apply a temporal decay function to an existing reputation or trust score, particularly in agentic systems, social graphs, or leaderboard contexts where inactivity should reduce standing. Prefer this over static score storage or manual recalculation when you want an automated, consistent decay model applied to structured reputation data.

## Known failure modes

- Missing or malformed 'data' field returns a validation error
- Unparseable date or score values in the data string cause processing failure
- Ambiguous decay model parameters may result in a default or fallback computation
- Network timeout or service unavailability returns a 402/503 error
- Empty data string results in null or zero output

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a computed reputation score after applying a time-based decay function to the input data, likely including the decayed score value, the decay delta, and possibly intermediate metrics like decay rate or time elapsed.
