## 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-claude-pricing-snapshot-f8690d8e
```

Example prompt: What are Claude's current pricing plans, costs, and features? Pull the latest structured snapshot so I can see plan names, prices, billing periods, and any listed features.

## When to prefer this

Use this endpoint when you need structured, machine-readable SaaS pricing data for Claude specifically, without scraping Anthropic's website yourself. Prefer this over manual web scraping when you need plan-level detail (names, prices, billing period, features) in a consistent JSON format, refreshed approximately every 6 hours. Ideal for agents doing pricing comparisons, budget analysis, or monitoring for price changes.

## Known failure modes

- 404 if the catalog slug does not exist — no charge applied
- 503 if the monitor has never completed a successful check — no charge applied
- Payment failure if the x402 wallet lacks sufficient USDC on Base
- Network or upstream errors from the pricing page fetcher

## 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 object containing plan names, prices, currency, billing period, price text, available features (when present), and the timestamp of when the snapshot was taken. Returns 404 for unknown slugs and 503 if no successful check has been completed yet — both returned before any charge is applied.
