Electra Payment Index
How AI agents pay, compared
The protocols and providers that let an agent pay or get paid: what each one does, who supports it, and what it costs. Read on official pages and dated. Electra Index does not process payments.

|---|---|---|---|
| VisaVisa Intelligent Commerce / Trusted Agent Protocol | Card network | MCPMPPVisa TAP | No public fees found |
Fees are the public list prices on each provider's own pricing page (mostly US rates); negotiated and regional rates differ. A protocol is listed only when the provider states support on its own page: click a protocol to open that page. No ranking, no "winner": partnerships never change what is shown.
