도구
attest_verify
Verify a RISC Zero receipt against an image_id -> {valid, journal_b64}. Anyone can check an
attestation without trusting the prover. Paid (~$0.0002).
입력 스키마
{'type': 'object', 'title': 'attest_verifyArguments', 'required': ['receipt_b64', 'image_id'], 'properties': {'image_id': {'type': 'string', 'title': 'Image Id'}, 'receipt_b64': {'type': 'string', 'title': 'Receipt B64'}}}
catalog
List every service this gateway sells (text tools, Kaspa chain data, LLM tiers) with live
prices in KAS and USD. Free. Start here to see what's available and what calls cost.
입력 스키마
{'type': 'object', 'title': 'catalogArguments', 'properties': {}}
channel_config
Parameters for opening a kaspa-channel â a covenant-enforced payment channel that settles
per-call vouchers on Kaspa L1 with NO custodian (the trustless alternative to a prepaid
session). Returns the payee pubkey, min/max channel size, required expiry lead, and maxfee.
Free. Opening a channel means funding the channel covenant on-chain (payer holds the key), then
paying per call with signed vouchers â use the `k402` Python client (`pip install k402`,
k402.channel) to build the covenant and sign vouchers, since that flow needs your Kaspa key.
Returns {error} if this gateway hasn't enabled the (experimental) channel rail.
입력 스키마
{'type': 'object', 'title': 'channel_configArguments', 'properties': {}}
channel_status
Status of a kaspa-channel by its channel id (covenant id): funded value, amount spent via
vouchers, remaining, expiry, and whether it has been closed on-chain. Free.

classify
Classify text into one (or multiple, if multi=true) of 2-32 labels; the result is
constrained to your label set. Paid (~$0.0003 in KAS).
입력 스키마

covenant_broadcast
Broadcast a signed covenant tx (RpcTransaction JSON from covenant_build). MAINNET moves real
KAS â run covenant_check first. Paid (~$0.0003).

covenant_build
Assemble a covenant spend tx. Each input: {txid, index, entry, compute_budget?, and either
sigscript:{source,decl,args,is_leader?} to build a covenant sigscript server-side, or omit
sigscript for a P2PK input you sign locally}. Each output: {amount, address|script_public_key_hex,
covenant?:{authorizing_input,covenant_id}}. Returns the tx, a broadcast-ready rpc_transaction,
fee accounting, and (if fully authorized) a pre-verify. We never sign. Paid (~$0.001).

covenant_check
Local txscript pre-verify of a signed covenant tx BEFORE broadcast â catches script failures
that would otherwise cost you a broadcast. 'entries' are the spent UTXOs (covenant_utxos output
plugs in directly). Returns {all_ok, inputs:[{index, ok, error?}]}. Paid (~$0.0005).

입력 스키마
{'type': 'object', 'title': 'kaspa_networkArguments', 'properties': {}}
kaspa_tx_status
Mempool status of a Kaspa transaction. Absent from mempool means accepted-or-unknown â
confirm acceptance by checking one of its outputs with kaspa_utxos. Paid (~$0.00015).

입력 스키마
{'type': 'object', 'title': 'kaspa_utxosArguments', 'required': ['address'], 'properties': {'address': {'type': 'string', 'title': 'Address'}}}
open_session
Open a prepaid payment session: returns a session key and a personal Kaspa MAINNET deposit
address. Send KAS to the address from any wallet (min 0.25 KAS); confirmed deposits become
spendable balance within seconds and every paid tool call meters against it. Free. The session
is saved locally so subsequent calls use it automatically.
입력 스키마
{'type': 'object', 'title': 'open_sessionArguments', 'properties': {}}
payment_options
Which coins and schemes this gateway accepts for payment. Free. Ways to pay any paid tool:
a prepaid KAS session (open_session â simplest, no per-call step); per-call in any listed coin
(pay the offer a 402 returns, then pay_per_call); or, where the experimental 'kaspa-channel'
scheme is offered, a covenant payment channel that settles per-call vouchers on L1 with no
custodian (see channel_config). Coins may include Kaspa, Pearl, BTC, LTC, DOGE, BCH, DASH, and
EVM assets (ETC, ETH, USDC, USDT).
입력 스키마
{'type': 'object', 'title': 'payment_optionsArguments', 'properties': {}}
pay_per_call
Complete a PER-CALL coin payment. After a paid tool returns a 402 with pay_per_call_offers,
pay one offer on-chain from your own wallet, then call this with the 402's `endpoint` and
`request_body`, the chosen offer's `scheme` and `payment_id`, and your payment `txid`. The
gateway verifies the payment landed and returns the tool's real result. (Alternative to a
prepaid session â use this when you'd rather pay each call directly in a specific coin.)

{'type': 'object', 'title': 'pay_per_callArguments', 'required': ['endpoint', 'request_body', 'scheme', 'payment_id', 'txid'], 'properties': {'txid': {'type': 'string', 'title': 'Txid'}, 'scheme': {'type': 'string', 'title': 'Scheme'}, 'endpoint': {'type': 'string', 'title': 'Endpoint'}, 'payment_id': {'type': 'string', 'title': 'Payment Id'}, 'request_body': {'type': 'object', 'title': 'Request Body', 'additionalProperties': True}}}
prove_guest_upload

입력 스키마
{'type': 'object', 'title': 'prove_guest_uploadArguments', 'required': ['program_b64'], 'properties': {'program_b64': {'type': 'string', 'title': 'Program B64'}}}
prove_preflight
Execute a guest WITHOUT proving: exact cycle count + a signed price quote
{total_cycles, price_kas, quote_id, quote_expires}. Run this first â proving cost scales with
cycles by orders of magnitude. Paid (~$0.002).
입력 스키마
{'type': 'object', 'title': 'prove_preflightArguments', 'required': ['image_id'], 'properties': {'image_id': {'type': 'string', 'title': 'Image Id'}, 'input_b64': {'type': 'string', 'title': 'Input B64', 'default': ''}}}
prove_submit
Queue a proving job -> {job_id, cost_kas}. Pass quote_id (from prove_preflight; charged the
quote) or max_kas (skip preflight; priced on actual cycles, refuses if over the cap). Then poll
job_status and fetch job_result. Paid: the proof's cycle-based price (dynamic).
입력 스키마
{'type': 'object', 'title': 'prove_submitArguments', 'required': ['image_id'], 'properties': {'max_kas': {'type': 'number', 'title': 'Max Kas', 'default': 0}, 'image_id': {'type': 'string', 'title': 'Image Id'}, 'quote_id': {'type': 'string', 'title': 'Quote Id', 'default': ''}, 'input_b64': {'type': 'string', 'title': 'Input B64', 'default': ''}}}
read_url
Fetch a public web page and return its title + clean markdown; distill=true adds key-fact
bullets. Useful when you have no web access of your own. Paid (~$0.0012 in KAS).

lists, its chain-verified reputation (settled KAS volume + settlement count), and its payee
address. Free.
입력 스키마
{'type': 'object', 'title': 'registry_providerArguments', 'required': ['payee_pubkey'], 'properties': {'payee_pubkey': {'type': 'string', 'title': 'Payee Pubkey'}}}
registry_search
Discover providers in the k402 service exchange â an open marketplace of agent-payable
services, each settled trustlessly over a Kaspa payment channel directly with the provider (no
custodian). Filter by capability (e.g. 'summarize', 'llm:reason', 'zk-prove'), max USD price,
and minimum reputation (settled KAS volume, chain-verified). Results are ranked reputation-first.
Free. Returns each provider's endpoint, payee pubkey, price, channel terms, and reputation.

Semantic-search a collection you indexed earlier; returns top-k matches with scores.
Paid (~$0.0003 in KAS).
