Payment Session
x402 is discrete per-call. This adds the two billing shapes it lacks, settled in batches through x402 so you pay one transaction per settlement (not per tick — the only economical way to bill micro-usage given fees + ATA rent):
- metered (pay-as-you-go): accrue per-use charges, settle when they cross a
threshold.
- subscription (streaming): charge a fixed amount every period.
Pure accounting — it never moves money or holds a key. It tells the agent when and how much to settle; the agent pays via x402-pay's pay_x402. A hard maxTotalUsdc lifetime cap bounds every session, so a runaway stream can't drain past it.
Tools
| Tool | Does | |---|---| | open_payment_session | start a metered or subscription session with a maxTotalUsdc cap | | meter_usage | accrue pay-as-you-go usage (metered sessions) | | check_settlement_due | is a payment due, and for how much? (amount is capped at remaining budget) | | record_settled | record a paid settlement after pay_x402 succeeds | | close_payment_session | close; returns any final remainder to settle |
The loop
open_payment_session(payee, mode, cap)
metered: meter_usage(...) → check_settlement_due → if due: pay_x402(payee, amount) → record_settled
subscription: (time passes) → check_settlement_due → if due: pay_x402(payee, amount) → record_settled
close_payment_session → settle any remainderTrust model
- Non-custodial. This plugin only does accounting; the actual USDC settlement
is pay_x402 (your own wallet signs). It never holds a key or moves funds.
- Capped. Every session carries a hard
maxTotalUsdc;check_settlement_due
never returns an amount above the remaining budget.
Pairs with [x402-pay](../../skills/x402-pay) (settlement) and [web0-onboard](../web0-onboard) (identity + endpoint).
