## 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 cambrian-x402-influencer-credibility-api-adc26b50

Example prompt: Can you check how credible the influencer @elonmusk is on social media — I want to know if they're trustworthy before we consider a brand partnership?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use credibility signal for a specific social media influencer without committing to a subscription. It is ideal for autonomous agents running brand safety checks, fraud detection pipelines, or influencer vetting workflows where you only pay $0.05 per lookup. Prefer this over full social analytics platforms when you need lightweight credibility scoring rather than deep engagement analytics.

## Known failure modes

- Unknown or non-existent influencer handle returns empty array or 404
- Payment failure or insufficient USDC balance blocks the request
- Missing required query parameters returns a validation error
- Rate limiting if too many requests are sent in quick succession
- Stale or unavailable social data may return incomplete credibility signals
