outils
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).
Schéma d’entrée
{'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.
Schéma d’entrée
{'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.
Schéma d’entrée
{'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.
Schéma d’entrée
{'type': 'object', 'title': 'channel_statusArguments', 'required': ['channel_id'], 'properties': {'channel_id': {'type': 'string', 'title': 'Channel Id'}}}
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).
Schéma d’entrée
{'type': 'object', 'title': 'classifyArguments', 'required': ['text', 'labels'], 'properties': {'text': {'type': 'string', 'title': 'Text'}, 'multi': {'type': 'boolean', 'title': 'Multi', 'default': False}, 'labels': {'type': 'array', 'items': {'type': 'string'}, 'title': 'Labels'}}}
covenant_address
Derive the covenant P2SH address for a compiled script on 'mainnet' or 'testnet-10'.
Paid (~$0.0003).
Schéma d’entrée
{'type': 'object', 'title': 'covenant_addressArguments', 'required': ['script_hex'], 'properties': {'network': {'type': 'string', 'title': 'Network', 'default': 'mainnet'}, 'script_hex': {'type': 'string', 'title': 'Script Hex'}}}
covenant_broadcast
Broadcast a signed covenant tx (RpcTransaction JSON from covenant_build). MAINNET moves real
KAS â run covenant_check first. Paid (~$0.0003).
Schéma d’entrée
{'type': 'object', 'title': 'covenant_broadcastArguments', 'required': ['transaction'], 'properties': {'network': {'type': 'string', 'title': 'Network', 'default': 'mainnet'}, 'transaction': {'type': 'object', 'title': 'Transaction', 'additionalProperties': True}}}
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).
Schéma d’entrée
{'type': 'object', 'title': 'covenant_buildArguments', 'required': ['inputs', 'outputs'], 'properties': {'inputs': {'type': 'array', 'items': {}, 'title': 'Inputs'}, 'network': {'type': 'string', 'title': 'Network', 'default': 'mainnet'}, 'outputs': {'type': 'array', 'items': {}, 'title': 'Outputs'}, 'lock_time': {'type': 'integer', 'title': 'Lock Time', 'default': 0}, 'payload_hex': {'type': 'string', 'title': 'Payload Hex', 'default': ''}}}
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).
Schéma d’entrée
{'type': 'object', 'title': 'covenant_checkArguments', 'required': ['transaction', 'entries'], 'properties': {'entries': {'type': 'array', 'items': {}, 'title': 'Entries'}, 'transaction': {'type': 'object', 'title': 'Transaction', 'additionalProperties': True}}}

Schéma d’entrée
{'type': 'object', 'title': 'embed_textArguments', 'required': ['texts'], 'properties': {'texts': {'type': 'array', 'items': {'type': 'string'}, 'title': 'Texts'}}}

404 until done; results kept 24h. Free.
Schéma d’entrée
{'type': 'object', 'title': 'job_resultArguments', 'required': ['job_id'], 'properties': {'job_id': {'type': 'string', 'title': 'Job Id'}}}

Current Kaspa mainnet feerate buckets (sompi per gram of tx mass). Paid (~$0.00015).
Schéma d’entrée
{'type': 'object', 'title': 'kaspa_fee_estimateArguments', 'properties': {}}
kaspa_network
Kaspa mainnet status: DAA score, block count, difficulty, node sync state.
Paid (~$0.00015 in KAS).
Schéma d’entrée
{'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).
Schéma d’entrée
{'type': 'object', 'title': 'kaspa_tx_statusArguments', 'required': ['txid'], 'properties': {'txid': {'type': 'string', 'title': 'Txid'}}}
kaspa_utxos
UTXO set of a Kaspa mainnet address, including scriptPublicKey and covenant_id where set.
Paid (~$0.0003 in KAS).
Schéma d’entrée
{'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.
Schéma d’entrée
{'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).
Schéma d’entrée
{'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.)
Schéma d’entrée
{'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
Upload a RISC Zero program binary (the .bin risc0-build emits, base64) once; returns its
content-addressed image_id (also the verification key), reusable across proofs. Paid (~$0.01).
Schéma d’entrée
{'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).
Schéma d’entrée
{'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).
Schéma d’entrée
{'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).
Schéma d’entrée
{'type': 'object', 'title': 'read_urlArguments', 'required': ['url'], 'properties': {'url': {'type': 'string', 'title': 'Url'}, 'distill': {'type': 'boolean', 'title': 'Distill', 'default': False}}}
registry_provider
Full detail on one provider in the service exchange by its payee pubkey: every service it
lists, its chain-verified reputation (settled KAS volume + settlement count), and its payee
address. Free.
Schéma d’entrée
{'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.
Schéma d’entrée
{'type': 'object', 'title': 'registry_searchArguments', 'properties': {'limit': {'type': 'integer', 'title': 'Limit', 'default': 20}, 'capability': {'type': 'string', 'title': 'Capability', 'default': ''}, 'max_price_usd': {'type': 'number', 'title': 'Max Price Usd', 'default': 0.0}, 'min_reputation_kas': {'type': 'number', 'title': 'Min Reputation Kas', 'default': 0.0}}}
rewrite
Rewrite text per an instruction (tone, format, length...). Paid (~$0.001 in KAS).
Schéma d’entrée
{'type': 'object', 'title': 'rewriteArguments', 'required': ['text', 'instruction'], 'properties': {'text': {'type': 'string', 'title': 'Text'}, 'instruction': {'type': 'string', 'title': 'Instruction'}}}
search_index
Store documents [{id, text, meta?}] in a named server-side collection for semantic search.
Use an unguessable collection name and keep it secret. Paid (~$0.0015 in KAS).
Schéma d’entrée
{'type': 'object', 'title': 'search_indexArguments', 'required': ['collection', 'documents'], 'properties': {'replace': {'type': 'boolean', 'title': 'Replace', 'default': False}, 'documents': {'type': 'array', 'items': {'type': 'object', 'additionalProperties': True}, 'title': 'Documents'}, 'collection': {'type': 'string', 'title': 'Collection'}}}
search_query
Semantic-search a collection you indexed earlier; returns top-k matches with scores.
Paid (~$0.0003 in KAS).
Schéma d’entrée
{'type': 'object', 'title': 'search_queryArguments', 'required': ['collection', 'q'], 'properties': {'q': {'type': 'string', 'title': 'Q'}, 'top_k': {'type': 'integer', 'title': 'Top K', 'default': 5}, 'collection': {'type': 'string', 'title': 'Collection'}}}
session_status
Check the current payment session: deposit address, deposited / spent / remaining KAS.
Free.
Schéma d’entrée
{'type': 'object', 'title': 'session_statusArguments', 'properties': {}}
summarize
Summarize text or a public URL in at most max_words. Paid (~$0.001 in KAS).

against its balance â use after reconnecting to the hosted endpoint, or to carry one funded
session across clients. Returns the session's current balance. Free.
Schéma d’entrée
{'type': 'object', 'title': 'use_sessionArguments', 'required': ['session'], 'properties': {'session': {'type': 'string', 'title': 'Session'}}}
