## 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 x402-bazaar-rank-twitter-tagged-services-5ac6a3d2
```

Example prompt: Show me the top x402 services tagged with Twitter, ranked by how many paying wallets used them in the last 30 days — I want real usage numbers and the snapshot hash so I can verify the data.

## When to prefer this

Use this endpoint when you need ranked, usage-verified discovery of x402 services specifically in the Twitter/social category, and you want real 30-day telemetry (calls and paying wallets) rather than self-reported metadata. Prefer this over generic x402 directory lookups when you need a reproducible, auditable snapshot with a receipt hash — especially useful for agent workflows that need to select or compare Twitter-adjacent x402 APIs by actual market activity.

## Known failure modes

- No services indexed under the twitter tag — returns empty services array with count 0
- Stale snapshot if the indexer hasn't refreshed recently — generatedAt timestamp will reveal lag
- Cloudflare Worker cold-start latency on first request
- Upstream x402scan indexer outage causes stale or missing data
- Malformed response if scoring revision schema changes
