What exactly does this provider support, where is it licensed and what does it charge? Paid ($0.01 USDC): Full cited record for one provider: stablecoin rails, corridors, licences, published fees, coverage, developer and agent-payment support. Every fact has source URL, retrieval date, quote and confidence. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/provider. Pay with your own x402/MPP client and retry that URL.

Who can on-ramp, off-ramp, issue or settle this stablecoin, on which chain, in which country? Paid ($0.01 USDC): Stablecoin rails by asset, chain, country and service, with the cited stablecoin block for each matching provider (assets, chains, ramp countries, fiat rails, custody model). Country matches say whether the country is listed or only covered by a 'global' claim. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/stablecoin-rails. Pay with your own x402/MPP client and retry that URL.

Who can move money from this currency or stablecoin to that one, in this country, over which rails? Paid ($0.03 USDC): Money-movement routes from one currency or stablecoin to another: corridors providers publish (rails, speed, fee notes, cited), plus on/off-ramp routes inferred from ramp coverage, labelled as inferred. This server holds no wallet and never pays: it returns the HTTP 402 payment requirements (x402 on Base, MPP on Tempo) and the URL https://payments-intel-production.up.railway.app/v1/corridor. Pay with your own x402/MPP client and retry that URL.
