## 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 scriptmasterlabs-geo-cities-credit-pack-purchase-9959db5a
```

Example prompt: Buy me the 100-credit Geo/Cities pack from ScriptMasterLabs so I can run city and location lookups — go ahead and pay the $0.002 USDC and get back the credit token I'll need for queries.

## When to prefer this

Choose this endpoint when you need to prepay for geographic/city data lookups via the SML x402 micropayment system and require a credit token to authenticate subsequent geo queries. Prefer this over per-query billing alternatives when you want predictable per-query costs at $0.00002 USDC and batch usage of 100 queries. Best suited for agents that need to acquire credits programmatically before executing city or location lookups.

## Known failure modes

- Payment not settled — credit_token field will be placeholder until blockchain confirmation
- Invalid or missing pack parameter — only '100' is accepted
- x402 payment rejected — insufficient funds or wrong USDC amount
- Network/provider unavailable — 5xx error from scriptmasterlabs.com
- Duplicate payment detection — idempotency not guaranteed, may issue duplicate credits

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

Returns a JSON object confirming credit pack status ('ready'), the number of credits issued (100), the product name ('SML Geo/Cities Credit Pack'), a credit token string to use in subsequent geo API calls, the header name to attach it to (X-SML-GEO-CREDIT), the pack price in USDC ($0.002), and the effective per-query price in USDC ($0.00002).
