Tool changes

  • buy_creditsadded

    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.

  • monetize_apiadded

    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.

Tools (6)

buy_creditsHow 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_statusWhat 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 Call this before advertising a price, because a network that cannot settle is withdrawn here first.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_resourceSearch 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_snippetWorking 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_apiPut 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_priceWhat a settlement costs through this facilitator, per network, with the basis it was computed from. Free while the service is in launch pricing.
