> DealPulse Deal Verification Check is a paid API for AI agents from dealpulse.theaslangroupllc.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

## 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 dealpulse-deal-verification-check-a00be9fc
```

Example prompt: Before I check out at Nike.com, can you verify whether the code SAVE20 is actually real and active right now — check their official site and any loyalty perks — and tell me if it's confirmed, unverified, or has no trace?

## When to prefer this

Use this endpoint when an AI checkout agent needs to validate whether a coupon code or advertised deal is genuinely active at a retailer before applying it, especially to avoid fake or expired third-party coupon aggregator codes. Prefer this over generic coupon endpoints when source-linked first-party verification and a confirmed/unverified/no-trace code verdict are required.

## Known failure modes

- Merchant site is temporarily unavailable — cannot fetch live offers
- Submitted code not found in any first-party source — returns 'no trace' verdict
- Store has no current promotions — returns empty offer list
- Invalid or unrecognized merchant identifier — returns 400 error
- Rate limit exceeded — returns 429 error

## How this service works

Verify which deals are REAL at a store right now: first-party-only check of the merchant's own site, feeds and loyalty/newsletter perks, every offer source-linked; optional claimed-code verdict (confirmed / unverified / no trace). The anti-fake-coupon endpoint for checkout agents.

## Output

Returns a list of currently active, source-linked offers found on the merchant's own site, official feeds, and loyalty/newsletter channels, plus an optional verdict on a submitted coupon code: confirmed, unverified, or no trace found.
