## Tools (36)

- `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).
- `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 wh
- `channel_config`: Parameters for opening a kaspa-channel — a covenant-enforced payment channel that settles per-call vouchers on Kaspa L1 with NO custodian (the trustless alterna
- `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. 
- `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).
- `covenant_address`: Derive the covenant P2SH address for a compiled script on 'mainnet' or 'testnet-10'. Paid (~$0.0003).
- `covenant_broadcast`: Broadcast a signed covenant tx (RpcTransaction JSON from covenant_build). MAINNET moves real KAS — 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
- `covenant_check`: Local txscript pre-verify of a signed covenant tx BEFORE broadcast — catches script failures that would otherwise cost you a broadcast. 'entries' are the spent 
- `covenant_compile`: Compile a Silverscript covenant to script hex, ABI, hardened template hash, and its P2SH address on each network. constructor_args is the silverc ctor JSON (e.g
- `covenant_utxos`: Live UTXO set locked under a covenant address (covenant state inspection), from the node. Optionally filter by covenant_id. Paid (~$0.0003).
- `embed_text`: Embed up to 64 texts (768-dim vectors, nomic-embed-text). Paid (~$0.0003 in KAS).
- `extract`: Extract structured data from text as JSON guaranteed to match your JSON schema (schema-constrained decoding, not best-effort). Paid (~$0.0015 in KAS).
- `generate`: Run a prompt on a GPU model tier: 'chat' (fast 7B, ~$0.0015), 'llama' (budget 8B, ~$0.0008), 'reason' (35B, ~$0.004), 'think' (deep chain-of-thought 35B MoE, ~$
- `job_result`: Fetch a finished proving job's result {image_id, total_cycles, journal_b64, receipt_b64}. 404 until done; results kept 24h. Free.
- `job_status`: Poll a proving job: queued/running/done/failed, queue position, cost. Free.
- `kaspa_balance`: Balance of any Kaspa MAINNET address, straight from a node (no indexer, no API key). Paid (~$0.00015 in KAS).
- `kaspa_fee_estimate`: Current Kaspa mainnet feerate buckets (sompi per gram of tx mass). Paid (~$0.00015).
- `kaspa_network`: Kaspa mainnet status: DAA score, block count, difficulty, node sync state. Paid (~$0.00015 in KAS).
- `kaspa_tx_status`: Mempool status of a Kaspa transaction. Absent from mempool means accepted-or-unknown — confirm acceptance by checking one of its outputs with kaspa_utxos. Paid 
- `kaspa_utxos`: UTXO set of a Kaspa mainnet address, including scriptPublicKey and covenant_id where set. Paid (~$0.0003 in KAS).
- `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); conf
- `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
- `payment_options`: Which coins and schemes this gateway accepts for payment. Free. Ways to pay any paid tool: a prepaid KAS session (open_session — simplest, no per-call step); pe
- `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
- `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 — proving cost scal
- `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 
- `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 (~$0.001
- `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 
- `registry_search`: Discover providers in the k402 service exchange — an open marketplace of agent-payable services, each settled trustlessly over a Kaspa payment channel directly 
- `rewrite`: Rewrite text per an instruction (tone, format, length...). Paid (~$0.001 in KAS).
- `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
- `search_query`: Semantic-search a collection you indexed earlier; returns top-k matches with scores. Paid (~$0.0003 in KAS).
- `session_status`: Check the current payment session: deposit address, deposited / spent / remaining KAS. Free.
- `summarize`: Summarize text or a public URL in at most max_words. Paid (~$0.001 in KAS).
- `use_session`: Attach an existing k402 session key (from a previous open_session) so paid calls meter against its balance — use after reconnecting to the hosted endpoint, or t
