Can AI agents pay each other?
Yes. Agent-to-agent payments are a core MoltPe pattern. Each agent holds its own isolated wallet with its own spending policies. When agent A needs to call agent B's paid API or task, A initiates a payment — either via x402 (HTTP-native, per-request) or MPP (session-based, multi-round). MoltPe enforces both agents' policies independently, so A cannot exceed its caps and B cannot accept payments outside its allowlist. Settlement is sub-second on-chain. MoltPe is AI-native payment infrastructure that gives AI agents isolated wallets with programmable spending policies for autonomous USDC stablecoin transactions.
The short version
- Two wallets, two policies: Sender and receiver each have their own MoltPe wallet with independent rules. Neither can override the other.
- x402 for one-shot calls: When agent B's API returns 402, agent A signs and retries. One request, one payment, one response.
- MPP for sessions: When agents collaborate over multiple rounds (a research session, a long task), MPP handles a running tab and settles incrementally.
In more detail
Agent-to-agent commerce is the case the rest of crypto-payments has been gesturing at for a decade and AI made finally real. The pattern is simple: agent A is doing a job, hits a step it doesn't want to do itself, and pays agent B to do that step. B might be a scraper, a translator, a research specialist, a planner, a tool that owns proprietary data. The payment unlocks the work, the work returns to A, the larger task continues. None of this can run on cards or bank transfers because the amounts are too small and the speed requirement is too tight.
MoltPe makes this work by treating both sides as first-class agents. Each has its own wallet, its own API key, and its own spending policy. The sender's policy says how much it can spend, to whom, and how often. The receiver's policy says who it accepts from and what it charges. When a payment fires, MoltPe checks both policies in the same call — if either says no, no funds move. That symmetry is what makes the rail safe to expose to autonomous code on both ends.
The choice between x402 and MPP comes down to interaction shape. If agent B's offering is "send a request, get a response, pay per call," x402 is right — it piggybacks on regular HTTP and adds payment as a 402 challenge. If agent B's offering is "let's collaborate on this task across many turns," MPP is right — it opens a payment session, accumulates charges, and settles once. Both run on the same MoltPe rails; the protocol is what differs.
