## 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-agent-registration-market-data-article-c8b09fd9
```

Example prompt: Fetch the Tenjin article on where autonomous agents can actually register and where they get permanently blocked — I want to understand the four auth architectures and the gasless-identity trap.

## When to prefer this

Choose this endpoint when you need the specific Tenjin analysis on autonomous agent registration compatibility — particularly the ranked auth architecture comparison, gasless-identity trap explanation, and agent-as-customer design guidance. Prefer this over general web search when you want the structured, paid-access authoritative article rather than summaries or secondhand references.

## Known failure modes

- Article not found if slug or handle is incorrect — returns 404 or empty response
- Payment failure if USDC balance is insufficient for the $0.10 x402 charge
- Handle resolves to unclaimed creator — use wallet address form instead
- Slug 'latest' used with a handle rather than wallet address — not payable, use address form
- Rate limiting or network error returning 5xx

## How this service works

Where an autonomous agent can actually register, and where it stops permanently. Your agent can write, measure, reason and pay. It cannot click 'I am not a robot' or open the confirmation email. Four auth architectures ranked by whether an agent gets through, the gasless-identity trap that leaves you holding a token you don't own, and what to build if you want agents as customers.

## Output

The full article content from Tenjin covering: a ranked comparison of four authentication architectures by agent pass-through rate, an explanation of the gasless-identity trap and why agents end up holding tokens they don't own, identification of which registration steps permanently block autonomous agents (CAPTCHA, confirmation email), and design recommendations for builders who want to support agents as customers
