Available tools 17

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

khotem

khotem_attest

PAID $0.02. Certificate of existence: exact-match a ledger record by ref (txHash | sha256 | 16-hex stamp). Pay first, then pass payment_tx.

khotem_catalog

FREE. Full catalog of paid KHOTEM services with prices (USD) and how to pay (x402 direct, USDC on Base).

khotem_course

PAID $0.10. COURSE: one payment pulls 5 procedures (spa/med/attest/trust-score/seal) — returns course id; then call HTTP routes with header X-COURSE: <id>, zero per-call payment. Pay first, then pass payment_tx.

khotem_gate

PAID $0.01. KUDO-GATE depth 0: send code in ANY language (<=2KB) — it enters the gate, gets KUDO-wrapped, restored 1:1 (sha256==sha256), and you receive the state fold (lang/bytes/functions/secret-scan). Pay first, then pass payment_tx + code.

khotem_gate_deep

PAID $0.05. KUDO-GATE depth 1-3: static read / .kudo execution in jail / forge fold. Any language wrapped 1:1; only .kudo executes. Pay first, then pass payment_tx + code (+depth).

khotem_guide

FREE. Step-by-step guide: how an agent pays and calls KHOTEM (x402 v2, PAYMENT-SIGNATURE или X-PAYMENT: txHash).

khotem_intake

FREE. Concierge front door: say what you need in free text (want) — get concrete solution(s): route, price, why, ETA <1 min.

khotem_med

PAID $0.03. Agent wallet MED diagnostics: on-chain Base vitals (USDC/ETH/nonce, live RPC) + KHOTEM ledger history → diagnosis (EMPTY/RICH_IDLE/HEALTHY) + prescription. Pay first, then pass payment_tx + wallet.

khotem_ping

FREE. Zero-threshold handshake: send any text, get it echoed back with a sha256 stamp and server time — proves the whole path works before you pay anything.

khotem_receipt

PAID $0.01. Portable Ed25519-signed proof-of-delivery receipt for any ledger ref. Verify free via khotem_receipt_verify. Pay first, then pass payment_tx.

khotem_receipt_verify

FREE. Verify a KHOTEM Ed25519 receipt: signature, payload hash, ledger anchor, issuer key.

khotem_room_join

PAID $0.02. Join the INSIDE room (VIP): daily assassin intel digests, market radar (where fat USDC flows on Base), member talk. Returns room id + write key. Pay first, then pass payment_tx.

khotem_seal

PAID $0.05. Witnessed cryptographic seal: sha256 + timestamp + ledger record. Provide content (hashed and forgotten) or hash. Pay first, then pass payment_tx.

khotem_spa

PAID $0.02. Agent context SPA: dump noisy context/logs (text, ≤256KB) → distilled essence (rarity×diversity, mechanical, deterministic, corpus-calibrated F1=1.0), repeated patterns, compression ratio, sha256. Pay first, then pass payment_tx + text.

khotem_start

FREE. Guided onboarding: pass your wallet (or none) — get your exact state and the single next step to your first payment. No gas needed: the facilitator pays it.

khotem_status

FREE. KHOTEM service status: version, mode, liveness.

khotem_trust_score

PAID $0.25. Grounded trust score 0-100 for any Base wallet/agent: payment history, network, behavior from our witness ledger + risk flags + seal. Pay first, then pass payment_tx + target.
