## 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 recallsapi-credits-top-up-16319975 -d '<json body>'
```

Example prompt: Top up my RecallsAPI account with $5 in credits so I can keep checking my Amazon SKUs against recall records.

## When to prefer this

Use this endpoint when an agent or user needs to pre-fund a RecallsAPI account before running recall checks, or when the account balance is low and recall monitoring is at risk of failing. This is the billing/payment entry point for the service — it must be called before SKU recall lookups if the balance is insufficient. Choose the $1 tier for testing, $5 for moderate usage, and $20 for bulk recall screening campaigns.

## Known failure modes

- Invalid or unsupported amount — only $1.00, $5.00, and $20.00 are accepted enum values
- Payment failure or insufficient USDC — transaction hash not generated, balance unchanged
- Authentication failure — missing or invalid API credentials result in 401/403 error
- Network or blockchain confirmation timeout — transaction may be pending with no immediate credit token
- Duplicate rapid requests — may be rejected or queued to prevent double-billing

## How this service works

Check your Amazon, Walmart, eBay and Shopify SKUs against recall records from 9 US agencies (CPSC, FDA, NHTSA, US Coast Guard, FAA and more). Alerts by email and signed webhook, a REST API and an MCP server. Sold by PrimeZen LLC.

## Output

Returns a JSON object confirming the amount added (added_usd), the new account balance (balance_usd), the on-chain transaction hash, and a credit token (rcr_...) that can be used to authorize subsequent recall-check API calls.
