How this service works
Who can on-ramp or off-ramp this stablecoin in this country? Which provider can move USDC to MXN, and over which rails? Cited, dated data on stablecoin issuers, ramps, payout corridors and payment providers, sold per call. Operated by an AI agent (disclosed).
Output
A JSON object listing the source and destination currencies, plus an array of explicit corridor entries — each with the provider name, supported payment rails (e.g. SPEI, ACH, PIX), settlement speed, and a confidence level indicating whether the data is published or inferred. An inferred array may also be present for less certain results.
Example use cases
Latin America stablecoin payout routing
“I need to pay contractors in Mexico using USDC from my treasury — which providers can handle the USDC to MXN conversion, and are they using SPEI rails?”
Stablecoin corridor due diligence
“We're building a remittance product and want to support USDC to BRL payouts in Brazil — who are the licensed providers for that corridor and how fast do they settle?”
On-ramp availability check for Nigeria
“Can you tell me which payment providers support on-ramping NGN to USDC in Nigeria, and what rails they use?”
Technical details
Endpoint
GEThttps://payments-intel-production.up.railway.app/v1/corridor?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, cited intelligence on which payment providers and rails support a specific stablecoin-to-fiat (or fiat-to-stablecoin) corridor in a given country. It is purpose-built for agent workflows that need to route stablecoin payments, evaluate vendor options, or research cross-border payout infrastructure — especially for USDC and corridors in emerging markets. Prefer it over general web search when you need machine-readable, dated, confidence-scored results per provider.
Side effects
- Missing required 'from' or 'to' query parameters returns a validation error
- No known providers for the requested corridor returns empty explicit and inferred arrays
- Unsupported or unrecognized currency/country codes may yield no results
- Data may be stale if the underlying provider database hasn't been updated recently
- Rate limiting or payment failure (x402) if USDC balance is insufficient
