## 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 oceanalt-prepaid-decision-credits-27d611d8 -d '<json body>'
```

Example prompt: Buy me a prepaid bundle of 100 OceanAlt decision credits so my payment agent can start screening transactions — I want the credit token sent back so I can store it.

## When to prefer this

Choose this endpoint when you need to prepay in bulk for OceanAlt AI-agent payment-decision calls rather than paying per-call; ideal when running a long-lived agent that will make many payment screening requests over a year, as the prepaid bundle avoids per-call settlement overhead and gives a stable bearer token for agent configuration.

## Known failure modes

- Payment settlement failure — USDC payment not confirmed, no token issued
- Token already issued for this settlement — idempotency violation, duplicate purchase attempt
- Invalid or missing required POST body fields — 400 Bad Request
- Credits endpoint temporarily unavailable — 503 or timeout
- Token lost after first display — shown_once:true means no retrieval endpoint exists

## How this service works

Prepaid credits for the sanctions and AML pre-payment decision: 100 calls to /api/x402/decision for one settlement, valid 365 days.

## Output

Returns a JSON object containing a one-time-shown credit_token string (prefixed 'oac_') to be sent as the X-OceanAlt-Credit header on future /api/x402/decision calls, the integer credits count (100), an ISO 8601 expires_at timestamp roughly 365 days out, and a shown_once boolean confirming the token will not be returned again.
