Naira Rates API
"Pay-per-call naira rates for people and AI agents."
Naira Rates API Case Study
The Challenge
People and AI agents need current USD/NGN rates and conversion, but typical rate services require accounts, API keys and upfront plans before you can fetch a price.
The Solution & Architecture
A pay-per-call endpoint with no accounts or API keys: an agent hits the endpoint, receives an HTTP 402 with the price, signs a gasless USDT payment on Celo through x402, and gets the official and street rates plus conversion back.
Impact & Results
On-chain pay-per-call USD/NGN rates and conversion for agents and users, built for Celo's Agents on Open Rails hackathon.
- Pay-per-call USD/NGN rates endpoint
