The open routing layer for global money
Coinnect is an open money transfer routing engine. It finds the cheapest path to send money between any two currencies — fiat, crypto, or P2P — by comparing 80+ adapters worldwide in real time. Think of it as the plumbing layer that maps every money rail on the internet, so anyone can find the best route.
The Google Maps of money transfers. Google Maps doesn't own the roads — it maps them, and lets you find the fastest route. Coinnect doesn't move money — it maps every corridor, exchange, and fee, so you always know the cheapest path. The routing data is open. Products get built on top.
What Coinnect does
Route discovery
Given a source currency, destination currency, and amount, Coinnect returns ranked routes — cheapest first — with full fee breakdowns, estimated delivery times, and step-by-step instructions.
80+ adapters
Crypto exchanges (Binance, Kraken, Coinbase, Bitso), fiat corridors (Wise, OFX, Flutterwave), remittance (Western Union, MoneyGram, Remitly), P2P markets, and central bank rates — all in one query.
Real-time rates
Background refresh every 3 minutes. Live order book data from exchanges. Official central bank rates from 15+ countries. Multi-hop route optimization via Dijkstra's algorithm.
Open data
The corridor graph, adapter list, and rate snapshots are public and free under CC-BY 4.0. Daily snapshots available on Hugging Face. No affiliate fees. No ads. No gatekeeping.
For developers and AI agents
Coinnect is built API-first. Every feature available on the website is available programmatically.
curl https://coinnect.bot/v1/quote?from=USD&to=MXN&amount=500
REST API
Simple GET endpoints. No signup required for 20 req/day. Free API keys for 1,000 req/day. Full OpenAPI spec at /docs.
MCP Server
Native MCP integration for Claude and compatible AI agents. Install via python -m coinnect.mcp_server and use as a tool.
x402 Micropayments
Pay $0.002 USDC per request on Base L2 for unlimited access. No accounts, no invoices — just HTTP 402 negotiation. Designed for agent-to-API commerce.
A2A Protocol
Google's Agent-to-Agent protocol compatible. Agents can discover Coinnect via /.well-known/agent-card.json and invoke skills programmatically.
Adapter coverage
Every route in Coinnect comes from a real data source. Here is a sample of the 80+ adapters connected today:
Central bank feeds: Banxico (MX), BCB PTAX (BR), TRM (CO), TCMB (TR), NRB (NP), NBP (PL), CNB (CZ), NBU (UA), NBG (GE), BOI (IL), BNR (RO), and more.
By the numbers
Part of the ceiba.to network
Coinnect is a node in the ceiba.to network — a fractal community protocol where tools, data, and governance are shared across independent projects. The routing data Coinnect produces feeds other ceiba nodes, and ceiba nodes contribute adapters and verification data back.
Vision
Moving money across borders is still opaque. Fees are hidden. Routes are locked behind proprietary platforms. People in the Global South — migrant workers, freelancers, small businesses — pay the highest costs because they have the fewest options visible to them.
Coinnect exists to make every money rail on the internet visible and comparable. The routing data should be open infrastructure, like road maps. When the map is open, anyone can build navigation on top — fintech apps, AI agents, community tools, remittance advisors.
The end state: you never overpay to move money, because every path is mapped and every fee is transparent.
How Coinnect is sustained
Free for humans
The website and basic API access are free forever. No signup, no ads, no affiliate fees.
x402 agent payments
AI agents and bots pay $0.002 USDC per request via x402 on Base L2. This is the primary revenue model.
API tiers
Commercial API keys for high-volume users. Free tier is generous (1,000 req/day).
Donations
Community donations via USDC, BTC Lightning, or ETH. Every donation keeps the lights on.
Built by KOA Labs
Coinnect is built and maintained by KOA Labs, a small studio focused on open infrastructure tools. KOA Labs also builds community protocols, data pipelines, and AI agent tooling.
