Test rail — Tollstile

import { createTollstile, memoryLedger, testRail } from "tollstile";

export const toll = createTollstile({ rails: [testRail()], ledger: memoryLedger() });

Send Payment: test to pay a fixed price, or pay against the quote from the 402:

Payment: test quote=<token> proof=p1 payer=agent_1 amount=$0.01 limit=$1.00

Parameter	Effect
`quote`	The quote token from the `402`. Required on dynamic routes.
`proof`	Stable proof id. Without it, every request is a fresh payment.
`payer`	Payer id, used by `limit()` and `payers()`.
`amount`	Must equal the price, otherwise the proof is invalid.
`limit`	Capacity of a reusable authorization.

Use testRail({ authorization: "reusable" }) to behave like an L402 credential or a KYAPay token. Over MCP, send the same string in _meta["tollstile/test-payment"].

See Test payment failures for rail.simulate() and rail.effects.

Never alongside live rails

createTollstile() refuses a test rail configured together with a live rail.
