## 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-x402-ecosystem-analysis-article-3cb2a02c
```

Example prompt: Pull up the Tenjin article about x402 being a Base and USDC monoculture — the one showing that 2,803 of 2,832 services accept only one chain, and that testnet listings are sitting in the production catalog.

## When to prefer this

Choose this endpoint when you need authoritative, data-driven analysis of the x402 payment protocol's real-world chain and currency distribution, specifically the Base/USDC monoculture finding and testnet catalog risk, as reported by Tenjin's research journalism. Prefer it over generic web searches when you need structured, paywall-gated research on x402 ecosystem statistics.

## Known failure modes

- Slug or handle not found returns 404
- Payment not completed or x402 payment rejected results in 402 with payment required details
- Network timeout if Tenjin blog is unreachable
- Testnet or invalid USDC payment address could result in lost funds with no content returned

## How this service works

x402 is a Base/USDC monoculture: 2,803 of 2,832 services accept exactly one chain. The protocol is chain-agnostic; the market is not. 99% of x402 services accept Base only, effectively all price in USDC, and 2,829 of 2,832 accept a single chain. Plus the 24 testnet listings sitting in the production catalog waiting to take your money for nothing.

## Output

Full article content from Tenjin analyzing x402 protocol ecosystem distribution: documents that 2,803 of 2,832 x402 services accept exactly one chain, that ~99% accept Base only, that virtually all price in USDC, and that 24 testnet listings appear in the production catalog posing a financial risk to users.
