## 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 tenjin-stablecoin-payments-census-article-c748534a
```

Example prompt: Pull up that Tenjin article on the 317,621 stablecoin payments census — I want to see the full breakdown of USDC payment activity on Base, including the median transaction size and the included dataset.

## When to prefer this

Choose this endpoint when you need empirical, measured data on real on-chain stablecoin payment activity — specifically the complete 30-day USDC/Base payment census with reproduction script. Prefer it over general DeFi dashboards or aggregators when you want a self-contained, verifiable dataset with methodology included rather than live aggregate stats.

## Known failure modes

- Article slug or handle not found — returns 404
- Payment not confirmed before content delivery — returns 402 if x402 payment flow fails
- Network or gateway timeout
- Handle resolves to unclaimed creator with no published article at this slug

## How this service works

317,621 stablecoin payments in 30 days, and every single one was USDC. A complete census of a payment network where every transaction settles on-chain: 317,621 paid calls in 30 days, 100.00% denominated in USDC, 100.00% on Base. Median payment $0.009 — half are under a cent, below the fixed component of card interchange. Small, extremely concentrated, and measured rather than asserted. Dataset and reproduction script included.
