## 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 pricing-state-api-clerk-pricing-snapshot-559fab41
```

## When to prefer this

Use this endpoint when you need machine-readable, structured Clerk pricing data without scraping their website yourself. Ideal for agents doing SaaS cost comparisons, pricing change monitoring, or budget planning workflows. Prefer this over raw web scraping when you need consistent JSON structure and don't want to handle HTML parsing. The $0.01 USDC per-call cost makes it economical for frequent polling.

## Known failure modes

- 404 — slug not found in catalog (no charge applied)
- 503 — monitor exists but has not yet completed its first successful check (no charge applied)
- Payment failure — x402 wallet not funded with USDC on Base
- Stale data — snapshot may be up to ~6 hours old depending on last fetch cycle

## How this service works

$0.01 USDC required (x402 / Base)

Paid 0.01 USDC. Structured snapshot for one catalog slug: plan names, prices, currency, billing period, price text, features when present, snapshot time. Unknown slug returns 404 and a monitor with no first successful check returns 503, both before charge.

No API key needed. Pay with any x402-compatible wallet that holds USDC on Base. If your agent does not yet have a funded wallet, set one up via Coinbase Agentic Wallet or Base MCP — then standard x402 clients will pay and retry automatically.

## Output

A structured JSON snapshot containing Clerk's current pricing plans — each with plan name, price amount, currency, billing period (monthly/annual), human-readable price text, and any listed features — along with the timestamp of when the snapshot was taken. Returns 404 if the slug is unknown, or 503 if no successful check has been completed yet (both before any charge is made).
