Anything an agent
pays for.
x402 turns any HTTP endpoint into something an agent can pay for autonomously. stealthPAY makes that spend feeless, fast, private, and governed. Seven places it lands first.
01
Use Cases
01
Pay-per-call APIs
The canonical x402 loop — 402 → pay → data, in ~1 second. stealthPAY gates the route and governs the spend.
02
Telegram pay-per-stream
A bot streams its AI response only after a confirmed micropayment — the whole loop finishes before the user feels a delay. No signup, no card.
03
Agent-to-agent marketplace
An orchestrator routes a query to a specialist agent and pays it automatically, with a markup — a marketplace inside the conversation.
04
Private consultations
Health, legal, financial questions answered by a bot — with the on-chain record revealing nothing about who paid whom or how much.
05
Gated content streaming
Preview → pause → micropayment → resume. Research, trading signals, premium newsletters — metered by the call, not the month.
06
B2B support bots
White-label AI support charging per resolved query, with full operator spend visibility and zero blockchain knowledge required.
07
Programmable allowances
Streaming budgets, auto-replenish, per-agent caps, anomaly alerts, instant kill-switch. Agent payroll, governed.

The Common Shape
The test
When it fits
High-frequency, low-value, machine-initiated — and better off private. Score all four and the case is a fit.
The anti-pattern
When it doesn’t
One-off, high-value, human-in-the-loop payments are a worse fit — that’s what cards and invoices already do well.
Every case above shares a profile: many small payments, made by software, where the metadata is sensitive.
That’s exactly the gap legacy rails leave open — fees too high, finality too slow, ledger too public, and no
governance over an autonomous spender. stealthPAY closes all four at once, which is what makes
these viable rather than merely possible.
