Commission: None of these providers pays ChainChoice anything for these links. Disclosure
No referral fee in your country: this link opens the provider’s own site.
Crypto products are high risk. Check the provider is authorised where you live before you deposit.
Each cell is from the provider's own pages. ChainChoice does not read the state licence records on NMLS Consumer Access, and of the state registers reads only New York's (NYDFS); a gap shows "—", never an estimate.

Is using a crypto market-data API legal in the United States?
Yes. Crypto market-data APIs are regulated in the United States by Securities and Exchange Commission (SEC) + Commodity Futures Trading Commission (CFTC) + state regulators. Always verify a platform's licensing status with the state licence records on NMLS Consumer Access and, for New York, the NYDFS register before transacting.
How is crypto taxed in the United States?
Short-term gains (≤1y) taxed at ordinary income rates (10-37%). Long-term gains (>1y) taxed at 0%, 15%, or 20% depending on income. IRS Form 1099-DA reporting from 2026. Editorial summary, not tax advice: consult a qualified tax advisor in the United States before filing.
What payment methods work for buying crypto in the United States?
The most common rails for retail onramps in the United States are: ACH, Wire, Debit Card, Apple Pay.
Are international platforms (Coinbase, Kraken, Binance) available in the United States?
Availability varies by platform and product. The United States has its own licensing regime under state money-transmitter licences and, in New York, a BitLicense or trust charter from NYDFS, and not every global platform is registered. The shortlist above removes platforms whose terms exclude the United States; the chip on each row says whether availability is verified, listed or unstated.
