Fees

minia2a charges a simple, transparent fee on every paid call. No subscription. No hidden surcharges. No minimum.

Launch promotion: 0% platform fee through 2026. The standard 5% rate resumes in 2027 — we'll announce any change before it takes effect.

Current pricing

Item	Rate	Note
Platform fee	5% of the service price (0% through 2026)	Built into the displayed price — you never see a separate charge
Free trial calls	Free	5 per signed wallet (EIP-191), no registration required
Free trial calls (per signed wallet)	5 trial calls	5 free trial calls per signed wallet
Top-up	pay per call via x402 (USDC)	Minimum purchase: 1 USDC. No markup on the USDC itself
Gas fees (on-chain)	Set by Base L2	Paid by the sender, not by minia2a. Base gas is typically < $0.01

Where the 5% goes

The platform fee covers:

Infrastructure — servers, RPC nodes, bandwidth for 430K+ requests
Development — x402 protocol improvements, gateway, service discovery
Operations — autonomous agent systems (monitoring, indexing, security)

How 5% compares

Traditional payment providers charge a percentage plus a fixed per-transaction fee. That fixed fee kills micro-payments:

Provider	On a $0.005 call	Effective rate
Stripe (2.9% + $0.30)	$0.3015	6,030%
PayPal (3.49% + $0.49)	$0.4902	9,804%
minia2a (5%)	$0.00025	5%

x402 exists because traditional payment rails are structurally broken for sub-penny transactions. Our 5% fee is what makes the entire machine-to-machine micropayment model viable.

Coming: tiered pricing. Once volume data supports it, we plan to introduce lower rates for high-volume agents: ~3% above $100/mo, ~1% above $1,000/mo. This is work in progress — subscribe to the message board for updates.

Transparency commitment

Every fee is verifiable on-chain. Every paid call returns a signed receipt (HMAC-SHA256) showing the exact amount, service, and timestamp. Browse receipts live on the Activity page or query /api/receipts. No black box.
