How this service works
🆕 The feasibility check before you ask a user for money: which fiat-in and cash-out rails Coinbase actually runs in a country, the currencies and min/max limits for each, and how many assets across which networks. Distinguishes a country with card rails from one where crypto can only be transferred in — a difference most integrations discover only after a user fails. 122 countries covered.
Output
A structured response listing the fiat on-ramp and cash-out rails available in the requested country, the currencies supported per rail, minimum and maximum transaction limits for each, the number of supported crypto assets, and the blockchain networks available — covering up to 122 countries.
Example use cases
Pre-launch country feasibility check
“We're about to launch our crypto app in Indonesia — can you check what Coinbase fiat on-ramp rails are available there, whether users can pay by card or bank transfer, and what the min/max limits are?”
Gating card rail UI for a specific market
“Before I show a credit card payment option to my user in Nigeria, check if Coinbase actually supports card rails there or if it's crypto-transfer only — I don't want them to hit a wall mid-checkout.”
Comparing fiat coverage across target markets
“I'm deciding between launching in Turkey, Poland, or Egypt first — can you pull the Coinbase on-ramp rails for all three countries so I can see which has the strongest fiat options and highest deposit limits?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/onramp-coverageWhen to prefer
Use this endpoint when you need a pre-flight feasibility check before presenting fiat payment options to a user in a specific country — it tells you exactly which rails exist (card, bank transfer, cash-out) and their limits, preventing failed user flows. Prefer this over generic payment provider docs when building integrations that need runtime country-level routing logic, especially when distinguishing card-capable markets from crypto-transfer-only markets.
Side effects
- Missing or invalid ISO country code returns an error
- Country not in the 122-country coverage list returns empty or unsupported result
- Network timeout if upstream Coinbase data is temporarily unavailable
- Stale data if Coinbase has recently changed rails in a country without cache invalidation
