## How to call it through Zero

```sh
zero fetch --capability pricing-state-api-twilio-pricing-snapshot-7eda32fe
```

Example prompt: Pull the latest structured pricing snapshot for Twilio — I need the plan names, prices, currency, and billing periods in a clean format.

## When to prefer this

Choose this endpoint when you need machine-readable, structured Twilio pricing data without scraping their website yourself. It is ideal for agents performing competitive pricing analysis, procurement comparisons, or monitoring SaaS cost changes over time. The pay-per-call x402 model (no API key required) makes it easy to integrate into automated agent workflows with a Coinbase Agentic Wallet.

## Known failure modes

- 404 if the slug 'twilio' is not in the catalog (returned before charge)
- 503 if the monitor has not yet completed its first successful check (returned before charge)
- Payment failure if the x402-compatible wallet lacks sufficient USDC on Base
- Stale data if the ~6-hour refresh cycle has not completed since last price change

## 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 Twilio's current public pricing: plan names, prices, currency, billing period, human-readable price text, features (when available), and the timestamp of when the snapshot was taken. Returns 404 if the slug is not in the catalog, or 503 if no successful check has been completed yet — both without charging.
