# Bitrefill Invoice Status & Redemption Code Retrieval

> Bitrefill Invoice Status & Redemption Code Retrieval is a paid API for AI agents from api.bitrefill.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-16).

Checks the payment status of a Bitrefill x402 invoice and, when authenticated via SIWX from the paying wallet, returns redemption codes for the purchased product.

## Facts

- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 bitrefill-invoice-status-redemption-code-retrieval-0c678d0f
```

Example prompt: Can you check whether invoice INV-abc123 on Bitrefill has been paid yet, and if so retrieve the redemption code using my wallet signature?

## When to prefer this

Use this endpoint after initiating a Bitrefill x402 purchase to confirm payment completion and retrieve the actual redemption code. It is the correct post-payment polling endpoint in the Bitrefill x402 flow, distinct from product search or invoice creation endpoints.

## Known failure modes

- Invoice ID not found — returns 404 or error indicating invalid invoice_id
- Invoice not yet paid — returns status without redemption codes
- SIWX authentication missing or invalid — returns status only, no redemption codes
- Invoice expired — returns expired status with no codes
- Wallet used for SIWX does not match paying wallet — codes withheld

## How this service works

Check an invoice status and, with SIWX from the paying wallet, retrieve redemption codes.

## Output

Returns the current status of the specified invoice (e.g. paid, pending, expired) and, when a valid SIWX signature from the paying wallet is provided, includes the redemption code(s) for the purchased gift card, airtime top-up, eSIM plan, or voucher.
