How this service works
CBN official rate, parallel market rate, USDT/USDC street price, and the spread between them. x402-gated API, no API key, no account.
Output
A structured response containing NGN exchange rates for each requested currency and market segment (CBN official, parallel, crypto street), including the bid/ask spread, a 7-day directional trend, and a confidence score indicating data reliability.
Example use cases
Parallel vs official rate arbitrage check
“Show me the current NGN/USD rate on both the CBN official and parallel markets, with the spread between them and the 7-day trend — I want to see how far apart they are right now.”
Crypto remittance stablecoin pricing
“What is the current naira street price for USDT and USDC? I need the stablecoin rates with confidence scores to figure out the best rate for sending money to Nigeria.”
Multi-currency FX dashboard for Nigeria
“Pull the latest naira rates for USD, EUR, GBP, and CAD across all three markets — official, parallel, and crypto street — so I can display them on a live dashboard.”
Technical details
Endpoint
GEThttps://nairarate.dev/v1/rates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, multi-market Nigerian naira FX data — especially when comparing the official CBN rate against the parallel (black market) or stablecoin street rate. It is the right choice when spread analysis, trend direction, and confidence scoring matter, and when you need coverage of stablecoin pairs (USDT, USDC) alongside fiat currencies. Prefer it over generic FX APIs that only report official rates and lack Nigeria-specific parallel market coverage.
Side effects
- Invalid market segment value returns 400 error
- Unsupported currency code in 'currencies' filter returns 400 or empty result
- Rate data temporarily unavailable for a specific market returns partial response or 503
- Network timeout if upstream data source is slow
- Payment failure (x402) if USDC balance insufficient
