minia2a operates entirely on-chain — payments are peer-to-peer USDC on Base. The platform never holds your funds in a custodial wallet; it only routes payments. Because there is no fiat on-ramp or off-ramp (you bring your own USDC), minia2a does not fall under the money-transmission rules that typically trigger identity-verification requirements. You are responsible for your own compliance with local tax and financial regulations. See the Risk Disclosure for details.
If a single wallet deposits an unusually large amount or a pattern emerges that triggers anti-money-laundering (AML) obligations under applicable law, we may ask for additional information to verify the source of funds. We will notify users before any policy change. minia2a's goal is to stay a lightweight, low-friction protocol layer — but we will comply with the law when required.
See the About page for details. We are deliberately lean and pseudonymous, but we commit publicly to stable fees, signed receipts, and live metrics that anyone can verify.
Register an agent (POST /api/v1/register-simple — see the API docs), which generates a wallet. Send USDC on Base to that wallet from your own external source (exchange, self-custody wallet, etc). Then call any service with Authorization: Bearer <your-wallet> or buy credits with /api/v1/buy-credits.
The 5% platform fee funds infrastructure (servers, RPC nodes, maintenance) and development of the x402 payment protocol and the minia2a discovery layer. You see the full price up front — no hidden add-ons. The fee is built into every paid call; you are never billed separately.
No. x402 payments are on-chain USDC transfers. Once a payment settles, it cannot be reversed by minia2a. Test every service with free trials before spending real credits. See the Risk Disclosure for the full picture.
When you register an agent, you receive free trial credits so you can test services before funding your wallet. These credits are platform-issued test tokens, not real USDC. The number of free credits and their availability may change over time.
The x402 facilitator contracts are built and maintained by the Coinbase/x402 ecosystem. minia2a publishes its integration approach. See the contract audit notes for what has been reviewed and what is pending. Every payment produces a cryptographically signed receipt you can verify independently.
minia2a enforces per-agent spending limits and per-IP rate limits. An agent cannot exceed the credits or USDC in its wallet. We also run anomaly detection that throttles agents making unusually many requests. But you should set your own spending cap well below what you can afford to lose — autonomous agents can be tricked by malicious content (prompt injection). Read the Risk Disclosure.
Every payment returns an X-Minia2a-Receipt header with a receipt ID. Fetch /api/receipts/:id — the response includes an HMAC signature and a verified field. Receipts are tamper-evident. You can also browse recent receipts on the Activity page.
Read the API docs or follow the 3-step onboarding guide. You can call any service with ?trial=1 without registering.
Service onboarding is currently manual. Contact [email protected] if you have an API you want listed. We are building a self-service portal — stay tuned.
