Returns dispute definition, required compelling-evidence exhibits, CE3.0 historical-order match rules, and 3-part rebuttal letter structure.
Output
Returns the matched dispute guide including: the card network and reason code, category, title, plain-English explanation of what the dispute means, a checklist of compelling evidence to gather, CE3.0 historical-order match rules (for Visa), prevention tactics, a 3-part rebuttal letter structure, a freshness date, and a disclaimer.
Example use cases
Rebutting a Visa fraud chargeback
“We received a Visa 10.4 dispute claiming the transaction was fraudulent — can you look up what that reason code means, what compelling evidence we need to submit, and give me the CE3.0 historical order match rules and rebuttal letter outline?”
Responding to Mastercard service dispute
“A customer filed a Mastercard 4853 chargeback against us. Can you look up what that reason code means and give me the evidence checklist and rebuttal letter structure we need to fight it?”
Amex dispute rebuttal preparation
“We got an Amex chargeback with code 13.3 — can you pull the dispute definition, the required compelling evidence exhibits, and the recommended 3-part rebuttal letter format so our team can prepare a response?”
Technical details
Endpoint
GEThttps://x402-niche-briefs.fly.dev/v1/chargeback-reason-code-guide?utm_source=zero.xyzWhen to prefer
Choose this endpoint when a merchant or payment operations agent needs a structured, actionable chargeback response guide for a specific card network reason code, particularly when CE3.0 Visa rebuttal strategy is needed. Best for automating dispute response workflows where the reason code is already known. Not suitable for open-ended dispute research beyond the four supported codes or for real-time network rule updates.
Side effects
- Unsupported reason code — only 10.4, 13.1, 13.3, and 4853 are supported; other codes return no match
- Unsupported network — only visa, mastercard, and amex are accepted; other values may return an error
- Stale guidance — the 'as_of' date indicates when the guide was last updated; CE3.0 rules may evolve
- Payment failure — $0.01 USDC x402 payment required; insufficient funds or unsupported wallet returns 402
