How this service works
Deterministic, letter-scoped preview of /api/deals/subscription-letter ($2.00): runs the same rule engine and reports whether a demand letter is supportable, its type (refund_demand | gift_letter | obstruction_letter), and the computed refund/exposure numbers. No letter text, no LLM. For full duties-in-force + violations + actions/defenses detail see /api/deals/subscription-rights ($0.05).
Output
Returns a deterministic verdict on whether a demand letter is supportable (yes/no), the classified letter type from the enum (refund_demand | gift_letter | obstruction_letter), and the computed refund or exposure dollar figures. No letter text is generated and no LLM is involved.
Example use cases
Pre-check subscription refund claim viability
“I've been charged for a gym membership I tried to cancel three times — can you check if a refund demand letter for that subscription is actually supportable and tell me the letter type and refund amount it would produce?”
Assess exposure before escalating dispute
“Before I spend money on a full subscription rights report, can you do a quick letter pre-check on my Adobe Creative Cloud billing dispute so I know the exposure numbers and whether it's worth pursuing?”
Classify demand letter type for a subscription trap
“I signed up for a free trial that turned into a paid subscription without a clear cancel option — run a subscription letter check and tell me whether this comes out as a refund_demand, gift_letter, or obstruction_letter and how much I could claim.”
Technical details
Endpoint
GEThttps://dealpulse.theaslangroupllc.com/api/deals/subscription-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap ($0.25) deterministic preview of whether a subscription demand letter is viable and what the financial figures look like, before committing to the full rights report at /api/deals/subscription-rights ($0.05 but with more detail) or the full letter generation at /api/deals/subscription-letter ($2.00). Ideal when you want a go/no-go signal and rough numbers without generating actual letter text.
Side effects
- Insufficient subscription detail provided — engine cannot compute refund figures
- Subscription scenario falls outside rule engine coverage — no letter type assigned
- Invalid or missing billing data — returns unsupported verdict
- Service unavailable or rate limit reached — HTTP error response
