Measured tools (6)

• facilitator_status

  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 Call this before advertising a price, because a network that cannot settle is withdrawn here first.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• settlement_price

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

  Parameters:

  • network — string — CAIP-2 network, for example eip155:8453. Omit for every network.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• find_paid_resource

  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.

  Parameters:

  • limit — integer
  • query — string — Words to match in the URL or description.
  • network — string — CAIP-2 network to restrict to.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• integration_snippet

  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.

  Parameters:

  • role — string — server to charge for a route, client to pay for one.
  • language — string
  • framework — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• monetize_api

  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.

  Parameters:

  • name (required) — string — What buyers see, for example 'Weather API'.
  • upstream (required) — string — Your API's https base URL.
  • price_usd (required) — number — Price per call in US dollars, paid in USDC.
  • pay_to (required) — string — Your EIP-55 checksummed wallet address.
  • key — string — Your Neuronto key (nc_ or nk_). Omit to get one.
  • description — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• buy_credits

  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.

  Parameters:

  • pack — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
