Why minia2a — The Trial-First Agent API Marketplace

The only agent API marketplace that combines free trials on every endpoint, facilitator-agnostic settlement, and EU hosting. 323 services, 402K+ requests, 11,250+ free trials served.

🔑 Three Things Nobody Else Does

1. Free trials on EVERY endpoint. 15 free calls per service. No wallet. No registration. No KYC. Agents discover by doing, not by reading marketing pages. Circle and Coinbase require wallets or accounts before the first API call. We don't. 11,253 trials prove this works.

2. Facilitator-agnostic. We don't run our own payment rail. Your API settlement happens through whichever x402 facilitator you choose — Coinbase, Cloudflare Wallets, Circle, Solana, or any standard x402 endpoint. No lock-in. No single issuer controlling your payment flow.

3. EU-hosted (Ireland). GDPR-compliant infrastructure. EU AI Act Art.50 aware. Not a US-only service that treats compliance as an afterthought. For European agent developers, this matters — and it's becoming a legal requirement.
