RelAI is a payments platform designed to enable developers and businesses to monetize their Application Programming Interfaces (APIs) using a pay-per-call billing model. ^[1] The platform is built on the Solana blockchain and utilizes the x402 protocol to facilitate on-chain micropayments for API usage. ^[2]

Overview

RelAI aims to provide a payments infrastructure for the API economy by leveraging the x402 protocol, a standard for machine-to-machine payments. The project's central objective is to offer an alternative to traditional payment platforms such as Stripe or PayPal, seeking to remove complexities like mandatory Know Your Customer (KYC) procedures and friction-heavy user onboarding flows. Instead of conventional subscription models, RelAI implements a pay-per-call system, where end-users are billed only for the API requests they actually make. ^{[1] [2]}

The platform is designed to integrate with existing API services without requiring developers to modify their current infrastructure. This is achieved through a reverse proxy architecture that adds the x402 payment layer directly on top of a provider's existing endpoints, effectively turning each endpoint into a distinct billable unit. This model is intended to be attractive for monetized services, as it aligns costs directly with consumption. ^[1] While its primary development is within the Solana ecosystem, the platform also supports payments across various EVM-compatible networks, indicating a multi-chain strategy. ^[3]

Architecture

RelAI’s technical architecture is centered on its implementation as a reverse proxy that integrates the x402 payment protocol. This design allows the platform to intercept API requests to manage a payment layer without requiring the API provider to alter their existing codebase. When a call is made to a monetized API, it is routed through RelAI's proxy, which handles payment verification before forwarding the request to the provider's server. ^[1]

The paid request flow is designed to have a total overhead of approximately 300 milliseconds and operates in several steps. First, a client sends a request to a monetized endpoint, which is intercepted by the RelAI system. The system then validates the micropayment associated with the request by confirming the transaction on the Solana blockchain, a step that takes approximately 200 milliseconds. Once payment is confirmed, the original request is sent to the API provider's server for processing. Finally, the server's response is routed back through the RelAI proxy to the end-user, and the revenue is credited to the provider's wallet. ^[2]

The platform is built to be blockchain-agnostic, with initial support for Solana and multiple EVM chains including Base, Polygon, and Ethereum. The system's marketplace shows the use of different payment "facilitators," such as Dexter x402 and PayAI x402, suggesting a modular design for its payment processing logic across different networks. Proxied calls are routed through the platform's x402.fi domain, with white-labeling options available for providers. ^{[3] [1]}

Products

RelAI's ecosystem consists of several core products for API providers and consumers.

API Marketplace

The RelAI Marketplace, located at relai.fi/market, serves as a public directory and central hub for the platform. It allows API providers to list their services and set custom pricing. For consumers and developers, the marketplace is a place to discover, browse, and integrate available pay-per-call APIs into their own applications. The listings provide details on functionality, pricing, and supported blockchain networks for each API. ^{[3] [1]}

Developer Dashboard

A web-based management interface is provided for API providers. This dashboard allows providers to register and configure their API endpoints, track revenue, and monitor usage and performance through Key Performance Indicators (KPIs). The dashboard serves as the primary tool for providers to manage their monetized services on the platform. ^{[2] [1]}

Software Development Kits (SDKs)

The project provides Software Development Kits (SDKs) to streamline the process for developers who wish to consume the monetized APIs listed on the RelAI marketplace. These SDKs are designed to help developers integrate their applications with the platform's payment and request-response flow. ^{[2] [3]}

Features

The RelAI platform offers a set of features focused on simplifying the process of API monetization. Its core feature is a pay-per-call billing model, which charges users for each individual API request rather than through a recurring subscription. The platform supports on-chain micropayments for these calls, with transaction fees starting as low as $0.01. ^[2]

Integration for API providers is designed to be a simplified process. The reverse proxy architecture allows providers to add the payment layer to their services without modifying their existing API code. Onboarding is streamlined to allow providers to begin monetizing by connecting a wallet, bypassing the need for extensive registration or KYC procedures. All payments are settled on-chain, with the project claiming transactions settle on the Solana blockchain in under two seconds. The platform also offers white-label options and multi-chain support, enabling payments on both Solana and various EVM networks. ^{[2] [3]}

Ecosystem

The RelAI ecosystem is composed of API providers who monetize their services, consumers who pay for those services on a per-use basis, and the underlying platform infrastructure. The RelAI Marketplace acts as the central point of interaction, connecting the two sides of the market. ^[1]

The platform operates across multiple blockchain networks to facilitate payments. Supported networks include:

• Solana
• Base
• Polygon
• SEI EVM
• peaq
• Ethereum

The ecosystem includes a growing number of integrated APIs available on the marketplace. Examples of listed services include the NovaShield Security Engine for analyzing Solana transactions, the TGM Backend API for Telegram group metrics, and an EVM Aggregator API for sourcing cryptocurrency swap routes. These integrations demonstrate the platform's adoption by third-party developers and service providers. ^[3]

Use Cases

The pay-per-call model supported by RelAI is applicable to a wide range of digital services and data offered via APIs. Potential use cases include: ^{[1] [3]}

• AI and Machine Learning Models: Enabling providers of AI models to charge for each inference, query, or data processing task.
• Data Services: Allowing data vendors to sell access to specific data points, reports, or real-time data feeds, such as financial market information or security analysis.
• Web3 and DeFi Tools: Facilitating monetization for developers of decentralized finance tools, such as trade aggregators or on-chain analytics services, on a per-use basis.
• Decentralized Physical Infrastructure Networks (DePIN): Allowing DePIN projects to bill for the consumption of real-world resources like bandwidth, storage, or computational power.
• SaaS and Micro-services: Offering a flexible pricing model for Software-as-a-Service tools, where services offered via an API can be broken down into billable units as an alternative to traditional subscriptions.

Tokenomics

RelAI has a native utility token, $REL, which operates on the Solana blockchain. The token is described as having deflationary mechanics, including auto buybacks and burns from platform revenue. The total supply of $REL is 1 billion tokens. ^[2]
