## 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 agentic-endpoints-testnet-buy-prepaid-credit-bundle-9077c195
```

Example prompt: Buy me $6 worth of prepaid API credits on agentic-endpoints-testnet for $5 USDC so I have a credit token I can reuse across paid calls without signing each one.

## When to prefer this

Choose this endpoint when you need to make multiple paid API calls on the same platform and want to avoid the overhead of signing a separate x402 payment for each individual call. It is especially valuable for agentic workflows with high call volume, or when you want a 20% cost saving by prepaying. Prefer this over per-call payment when you anticipate using more than one paid endpoint in a session.

## Known failure modes

- Payment of $5 USDC fails or is rejected — no token issued
- Insufficient USDC balance in calling wallet — HTTP 402 or payment error
- Network/worker error causing token not to be generated — HTTP 500
- Token already issued and not yet consumed — may return duplicate or error
- Invalid or missing payment authorization header — HTTP 401/402

## How this service works

Buy $6.00 of prepaid credit for $5.00 (20% bonus). Returns a credit token; send it as X-Credit-Token on any paid endpoint to be debited at list price with no per-call payment signature.

## Output

Returns a credit token (string) intended to be passed as the X-Credit-Token HTTP header on subsequent paid endpoint calls. The token represents $6.00 of prepaid credit, debited at list price per call, with no need for per-call payment signatures. The response likely includes the token value and remaining balance metadata.
