How this service works
Global deal intelligence API.

All endpoints support any language via ?lang=. Pricing: $0.05–$0.10 USDC/call via x402 micropayment.
Output
A formatted, state-specific demand letter (JSON with letter text) addressed to the subscription seller, citing applicable consumer protection laws for the specified US state, referencing the unauthorized charge amount, and asserting the consumer's right to cancel and obtain a refund. May include language specific to states with strong subscription laws (CA, NY, VT, OR, etc.).
Example use cases
Blocked cancellation complaint letter
“I've been trying to cancel my gym app subscription for weeks and they keep ignoring me. I'm in New York, the seller is FitFlow Inc., they've charged me $149.50 total, and cancellation is completely blocked. Can you draft me a formal demand letter?”
Unauthorized charge dispute letter
“A subscription service called MindfulBox charged me $59.99 without my affirmative consent and I'm in Oregon. Please write me a legal-sounding letter demanding they stop and refund me — I never agreed to these charges.”
Multi-state consumer rights letter
“I need a demand letter in Spanish for a subscription issue in Illinois — the seller is QuickLearn Pro, they charged me $199.00, I gave no consent, and they've blocked my cancellation. Can you generate that for me?”
Technical details
Endpoint
GEThttps://dealpulse-weld.vercel.app/api/deals/subscription-letterWhen to prefer
Use this endpoint when a consumer needs a formal, legally-inflected written demand to send to a subscription company — particularly when cancellation has been obstructed or charges were made without affirmative consent. Prefer this over generic letter generators because it is state-aware, referencing jurisdiction-specific consumer protection law. Best for US-based subscription disputes in the supported states.
Side effects
- Missing required 'state' parameter returns an error
- State code not in the supported list (CA, NY, DC, VA, IL, VT, OR, HI, DE, FL) may produce a generic or empty letter
- Empty response schema means output structure may vary unexpectedly
- Payment failure via x402 micropayment returns 402 status before letter is generated
- Invalid or missing total_charged may produce a placeholder amount in the letter
