## 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-resend-pricing-snapshot-a522c439
```

Example prompt: Can you pull the latest structured pricing snapshot for Resend — I need the plan names, prices, billing period, and any features listed, all in one go?

## When to prefer this

Use this endpoint when you need machine-readable, structured SaaS pricing data for Resend specifically, without scraping or parsing HTML yourself. Ideal for agents doing competitive analysis, cost estimation, or pricing change monitoring. Prefer this over raw web scraping when you need normalized fields (plan name, price, billing period) in a consistent schema, and when you have an x402-compatible wallet for the $0.01 USDC micropayment.

## Known failure modes

- 404 if slug 'resend' is not found in catalog (returned before charge)
- 503 if monitor has no first successful check yet (returned before charge)
- Payment failure if x402-compatible wallet lacks USDC on Base
- Stale data if the ~6-hour refresh cycle hasn't run recently

## 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 of Resend's pricing page, including plan names, prices, currency, billing period, human-readable price text, available features per plan when present, and the timestamp of when the snapshot was taken. Returns 404 if the slug is unknown, or 503 if the monitor has not yet completed its first successful check — both before any charge is applied.
