## 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 402-com-tr-credit-token-purchase-594c6199
```

Example prompt: I want to buy a $5 prepaid credit bundle for x402 so I can make lots of API calls without signing each one — get me a credit token using the 5-tier.

## When to prefer this

Use this endpoint when an AI agent or automated system needs to make many rapid calls to x402-priced services and wants to avoid per-call signature overhead and settlement latency. Ideal for high-frequency agents firing many checks per minute. Prefer the $20 tier for heavy usage (20% bonus) and the $5 tier for moderate usage (10% bonus).

## Known failure modes

- Payment not received or x402 settlement failed — no token issued
- Invalid tier value provided — only 1, 5, or 20 accepted
- Token issued but lost by caller — cannot be recovered (shown once only)
- Balance expired after 180 days — token no longer valid
- Insufficient USDC balance in caller's wallet to cover the $5 call price

## How this service works

Buy a prepaid balance in a single x402 settlement and get a secret credit token. Send it as the `x-credit-token` header on any paid service and each call debits its price from your balance — no per-call signature, no settlement latency. Built for agents that fire many checks a minute. Tiers: $0.25 (starter), $1, $5 (+10%), $20 (+20%). The token is shown once; balance lasts 180 days.

## Output

A secret credit token (shown once) that represents the purchased prepaid balance, usable as the x-credit-token header on subsequent x402-compatible API calls. The token carries the credited amount (with tier bonus: +10% for $5, +20% for $20) and remains valid for 180 days.
