Neuronto Payments: x402 facilitator and API gateway tools (6, 2 write)

write = sends, deletes, buys or posts
  • buy_creditswrite actionFree

    How to buy Neuronto credits, the one prepaid balance for every paid Neuronto call (searches past the free allowance, multi-step discovery, the change feed, publisher monitoring, gateway fees): the packs, what each thing costs, and the x402 URL to pay.

  • facilitator_statusFree

    What this x402 facilitator can settle right now: the live networks and schemes, whether the echo merchant is serving, the state of address screening, observed availability and settlement counts. Call this before advertising a price, because a network that cannot settle is withdrawn here first.

  • find_paid_resourceFree

    Search the catalogue of resources that have been paid for through this facilitator: the URL, the terms, the method, and the input and output shapes where the merchant published them. A resource is listed only after a real settlement and a probe, so nothing here is a claim by its owner.

  • integration_snippetFree

    Working code to start charging for a route through this facilitator, in the language and framework you name, plus a live URL to test the client against. Copy it as it is; the only thing to change is the wallet.

  • monetize_apiwrite actionFree

    Put an existing HTTPS API behind x402 without changing its code: returns a paid URL that answers 402 with your price, forwards paid calls to your API, and settles each payment straight to your wallet. 1,000 paid calls a month free, then 1% from prepaid credits. Pass your key, or omit it and a new one is returned.

  • settlement_priceFree

    What a settlement costs through this facilitator, per network, with the basis it was computed from. Free while the service is in launch pricing.

What the publisher says

From the Neuronto Payments: x402 facilitator and API gateway repository's README, as published. We do not edit it. Read it on GitHub

x402 starters

The shortest working way to charge for an HTTP route, and to pay for one, using the official x402 SDKs. Every file here runs as it is; the only thing you must change is the wallet that gets paid.

x402 revives HTTP 402 Payment Required. Your server answers an unpaid request with 402 and machine-readable terms, the client signs a stablecoin payment, and a facilitator verifies the signature and settles it on-chain. Your server never holds a key and never talks to a chain.

Pick one

Run one in a minute

cd express
npm install
export MERCHANT=0xYourWalletAddress      # where the money goes, on Base
npm start
curl -i localhost:3000/premium           # 402 with terms

Then pay it with a client from client, or point any x402 client at it.

The facilitator

These starters use https://pay.neuronto.com as the facilitator: the service that verifies the payer's signature and broadcasts the settlement. It is one line in every file, and any x402 facilitator can take its place:

new HTTPFacilitatorClient({ url: "https://pay.neuronto.com" })

Base mainnet (eip155:8453) is live there. GET https://pay.neuronto.com/supported lists every network, scheme and version it settles right now; a network that cannot settle disappears from that list before it starts refusing, so a server that reads /supported never advertises a price it cannot take.

Testing without spending anything

https://pay.neuronto.com/echo is a live merchant that charges $0.001 and sends it straight back in the same request, so a client can be run end to end for the cost of nothing:

curl -i https://pay.neuronto.com/echo        # a real 402, with real terms

Point any of the clients in client at that URL. The refund is automatic; the gas is not yours.

What you need

arrive as USDC transfers to the address you put in MERCHANT.

  • A wallet address to be paid to. Nothing is installed on your side to receive money: payments

from the environment.

  • For a paying client, a funded key. Never put a real key in a file: every example here reads it
