Inference + Marketplace.
One x402 platform.
Call first-party AI with OpenAI-compatible APIs, or monetise your own endpoints. Pay per request with wallet-native USDC on Sui and Solana — inference uses exact treasury payment; marketplace uses exact_split to providers.
From registration to revenue in six steps
Register any HTTP API, attach pricing, and start accepting per-request blockchain payments through protected routes on api.galliun.com.
Register API
Create a project and register your API on the Galliun platform.
Set pricing
Define per-request pricing for each endpoint — flat, token-based, or custom.
Configure chains
Enable payment rails on Sui and Solana.
Protected URL
Expose endpoints at /p/:projectSlug/* with automatic x402 gating.
Pay per call
Clients pay on each request via wallet — 402 challenge, sign, retry.
Analytics
Track usage, revenue, and cost breakdowns in the developer dashboard.
Infrastructure for every paid API surface
Galliun ships two paid API products — **Inference** (first-party LLM chat with x402 exact pay) and **Marketplace** (provider APIs with exact_split). Both run on Sui and Solana USDC.
Inference
OpenAI-compatible chat and embeddings with wallet-native x402 exact pay. Try it in Galliun Chat.
Marketplace routes
Every paid third-party endpoint lives behind /p/:projectSlug/*. x402 exact_split, verification, and usage tracking built in.
API directory
Discover marketplace API products, browse endpoints, and test protected routes from the playground.
Dashboard
Manage projects, APIs, endpoints, payment rails, API keys, and view usage analytics.
SDK
GalliunClient.inference for exact pay; GalliunClient.marketplace for exact_split protected routes.
CLI
Register APIs, sync pricing, and manage deployments from the terminal.
MCP integration
Monetise MCP server tools with the same x402 payment flow as HTTP APIs.
Any API that deserves per-request pricing
Paid APIs
Monetise REST and GraphQL endpoints with per-request pricing.
AI APIs
Offer inference, embeddings, and vision with token-based billing.
MCP tools
Charge for tool calls from MCP servers and agent frameworks.
Agent workflows
Pay-per-step execution for autonomous agents and pipelines.
Datasets
Sell access to curated data with metered queries.
Search
Per-query pricing for search and retrieval APIs.
Image processing
Bill for image analysis, generation, and transformation.
Document processing
Charge per document for parsing, OCR, and extraction.
One SDK for any protected route
GalliunClient handles x402 payment negotiation so you can call any /p/:projectSlug endpoint with a familiar fetch interface.
import { GalliunClient } from "galliun";
const client = new GalliunClient({
baseUrl: "https://api.galliun.com",
chain: "sui",
wallet,
});
const res = await client.fetch("/p/demo/summarize", {
method: "POST",
body: JSON.stringify({ text: "Summarize this article..." }),
});
const { summary } = await res.json();Direct x402 payments on chains you already use
Per-request x402 payments settle directly to your configured wallet. MVP support is Sui and Solana.
Solana
LiveHigh throughput, low fees.
Sub-second finality and negligible transaction costs for API micropayments.
Sui
LiveParallel execution, instant settlement.
Object-centric model for fast, predictable direct x402 payments on every request.
Payments you can trust at scale
Direct x402 payments are verified server-side with request binding, replay protection, and transparent cost disclosure. Galliun does not custody provider funds.
Request-bound payments
Every payment proof is cryptographically bound to the exact request hash — method, path, body, and pricing version.
Replay protection
Proofs are single-use. Replayed X-PAYMENT headers are rejected at verification.
Dedupe & idempotency
Duplicate payment submissions are detected and deduplicated to prevent double-charging.
Invite-only access
Dashboard access is invite-only — approved API providers sign in with secure email credentials.
Cost breakdown
Every 402 response includes transparent, itemized pricing before you pay.
Controlled production
New organizations start in restricted mode until Galliun approves production access.
Manage everything from one place
Projects, APIs, endpoints, payment rails, API keys, and usage analytics — all in the developer dashboard.
