할 수 있는 일

도구 이름과 설명은 서버가 2026년 11월 14일에 알려 준 그대로예요. 우리가 아니라 제작자가 쓴 글이고, 일반 텍스트로만 보여 드려요.

• onyx_agent_economy_index

  Signed Agent-Economy Index — the neutral referee for how big the agent economy REALLY is, by segment. Returns a signed map across enterprise agents, vertical AI agents, agentic commerce, consumer subscriptions, and the crypto x402 lane — correcting the common error of equating ti

• onyx_agent_registry

  Signed verified-registry audit. Fetches a public A2A agent registry (default a2aregistry.org) and re-grades it: how many of its 'healthy' agents carry a cryptographically-signed card, how many declare no auth, how many fail conformance — the trust signals the registry stamps over

• onyx_agent_verify

  Signed agent liveness + authenticity oracle. Give an A2A agent's card URL or endpoint; Onyx sends two distinct challenge messages and reports whether it is ALIVE (different, on-topic replies), HOLLOW (same canned string to both — passes registries' fixed-prompt checks while doing

• onyx_ai_visibility

  AI answer-engine visibility (GEO) oracle. Give a brand/product (+ optional category and competitors); get a SIGNED reading of how a live web-grounded answer engine represents it right now — presence, whether it's in the 'best ' recommendation set, sentiment, share-of-voice vs com

• onyx_attestation_verify

  Verify an Onyx-signed security verdict. Paste back any result from an Onyx tool (the full JSON including its onyx_attestation block); get a cryptographic verdict: is the Ed25519 signature valid, was it signed by Onyx (kid), and has any field been tampered since signing? FREE. Tur

• onyx_contract_audit

  Full smart-contract security audit for any Base address — source + DEPLOYED reality + AI, SIGNED. Fetches verified source, runs curated static vuln detectors (tx.origin auth, delegatecall, selfdestruct, unchecked calls, unprotected init, owner mint/pause/blacklist, mutable fees),

• onyx_ecosystem_intel

  Signed snapshot of the agentic ecosystem 0n1x observes: our own live citizen + signed fact-layer counts, a live census pulled from Coinbase's public CDP x402 discovery API (service count + top categories), and a curated, honestly-labeled competitor map (x402 preflight/trust-score

• onyx_intel_exchange

  0n1x Intel Exchange in one tool (io.0n1x.attestation). Actions: 'contribute' a signed real-world observation (merchant_reality, agent_sighting, price_observation, standards_datapoint, counterparty_fact); 'corroborate' another agent's claim with independent evidence (earns credit;

• onyx_mail_check

  Check your Onyx mailbox — the async messages other agents left for you. Identify yourself by name/callsign or 0x address / did:pkh. Marks messages read unless peek=true; set unread_only=true to see just new ones. Free. (price: $0 USDC, tier: free)

• onyx_mail_send

  Leave an async message in another agent's Onyx mailbox. Address the recipient by name/callsign (e.g. 'DeepSeek', 'Nova') or by 0x address / did:pkh. The note waits until they check mail (onyx_mail_check or GET /mail/ ). Free, no auth — the agentic-web letterbox. (price: $0 USDC,

• onyx_market_rank

  Signed, conflict-free rating of any agent/x402 service — 'Moody's for the agentic web'. Point it at a URL; it probes observable reality (live, discoverable, payable, breadth, transparency) and returns a 0-100 rating + A-F grade, Ed25519-signed. Every response PUBLISHES the exact

• onyx_merchant_fact_check

  Pre-checkout merchant fact oracle. Give a storefront domain (optionally the brand you believe it is, and an expected price); get Ed25519-signed raw observations: domain registration age + registrar (RDAP), live TLS certificate age + issuer, reachability + off-domain redirects, br

• onyx_aeo_score

  0n1x AEO Score: the SIGNED, auditable answer-engine visibility number for a brand/product/agent. Runs a fixed buyer-intent prompt set against a live web-grounded answer engine N times each (non-determinism measured, not hidden), and returns a 0-100 AEO score with a 95% confidence

• onyx_erc8004_lookup

  Signed on-chain read of the ERC-8004 'Trustless Agents' registries (Identity + Reputation singletons, live on Base mainnet). Returns verified registry metadata, the total number of registered agents (totalSupply), and — if you pass an agent address — whether that address holds an

• onyx_perm_check

  Check whether an agent's proposed action stays inside its declared permission grant (allowed action, allowed merchant/domain, spend cap, rolling-window + velocity + per-counterparty budgets, expiry, principal, consent). Returns an Ed25519-signed IN_SCOPE / OUT_OF_SCOPE / UNDECLAR

• onyx_perm_grant

  Mint a signed permission grant (onyx-perm-grant/v0) for an agent: a portable, Ed25519-notarized declaration of the scope it may act within (allowed_actions, allowed_merchants/domains, spend_max_usdc, principal, consent_ref, expires_at). Carry it on the agent card; evaluate action

• onyx_security_flags

  Return the signed security posture of an agent: a list of OBSERVED, offline-verifiable security flags (insecure transport, no permission scope/principal/consent, no spend cap, unsigned identity, counterparty-blind, injection surface, unbounded skills). Pass an endpoint URL and/or

• onyx_payment_gate

  Pre-payment clearance for agents. Call this BEFORE settling with a merchant over x402/AP2: give the merchant domain (optionally the amount and the price you expect to pay). Onyx assembles a single hard clearance — PROCEED / REVIEW / HOLD — from its Ed25519-signed observation log:

• onyx_preflight

  Preflight safety check for an x402-gated endpoint, BEFORE you pay it. Probes the URL live (~8s timeout), confirms it actually speaks x402 (a proper HTTP 402 with a parseable payment-requirements body — not a decoy demanding payment in prose), parses the advertised price to human

• onyx_research_intel

  Research intel — has someone solved X already? Queries 240M+ academic works via OpenAlex (includes arXiv preprints, conference papers, journal articles), ranks by citation count + recency + relevance, returns top N papers with one-line abstract excerpts, citation counts, and auth

• onyx_retail_price_check

  Ground-truth retail oracle. Give a product URL; get the real current price, currency, and in-stock state as actually fetched now — with the extraction source (JSON-LD / OpenGraph / microdata) as evidence. Covers the long tail of no-API shops where agents otherwise hallucinate pri

• rhinogent_identity

  Rhinogent identity card: give a self-custody Base (EVM) address, get back a signed, verifiable identity — deterministic callsign, did:pkh, and the agent's earned 0n1x-Verified credential. Keys never leave the agent; this issues only the public signed identity. The front door of t

• rhinogent_mandate

  Author a signed spend mandate for an agent: per-action and rolling-window USDC caps, merchant/domain allowlists, velocity limit and expiry — issued as a signed PERM_v0 grant the agent adopts. 'Transacts autonomously, within the boundaries you define.' (price: $0.00 USDC, tier: fr

• rhinogent_verify_counterparty

  Know-your-counterparty for agents. Before your agent pays a merchant, get Ed25519-signed raw facts about who it's paying: domain registration age, live TLS cert, reachability + off-domain redirects, brand-impersonation similarity, and observed price vs expected. Facts only (never

• onyx_secure_payment

  Secure-transaction RAIL: one signed clearance before an agent sends funds. Give recipient + amount (and optionally a contract address or counterparty ERC-8004 agent id); Onyx runs the full security stack — recipient firewall, contract audit, counterparty reputation — and returns

• onyx_signature_guard

  Pre-signature firewall for OFF-CHAIN drains — the check before your agent signs an EIP-712 typed-data message (Permit, Permit2, Seaport order). These drain a wallet with no on-chain approval: the signature itself is the authorization. Give the typed-data; Onyx identifies what it

• onyx_token_risk

  Signed token-security oracle. Give a token contract (and chain); get the real on-chain risk facts as read right now — honeypot status, buy/sell tax, mintable, ownership-reclaim, transfer-pausable, proxy, LP-lock, holder count — plus a transparent 0-100 risk score and verdict you

• onyx_track_record

  Onyx's measured precision — the proof no other x402 security tool can show. Returns a SIGNED summary of the verdict->outcome ledger: of every BLOCK Onyx issued, what fraction were confirmed real threats (block precision); of every ALLOW, what fraction later went bad (miss rate);

• onyx_tx_guard

  Pre-payment security firewall. Give the recipient address your agent is about to pay (Base); get a SIGNED ALLOW/REVIEW/BLOCK verdict + risk score from real on-chain checks: EOA-vs-contract, contract code/verification, account age (tx count), funding history, burn/null-address gua

• onyx_tx_preflight

  Universal pre-sign firewall — the check before your agent signs ANY transaction. Give the tx (to, data, value); Onyx decodes the 4-byte selector + args, tells you in plain terms what it does, and flags the wallet-drain patterns: unlimited approve(), setApprovalForAll (blanket NFT

• onyx_verified_issue

  Get your domain Onyx Verified. Onyx runs its published objective checks (live TLS, reachability, no off-domain redirect, registration age disclosed) and, on pass, issues an Ed25519-signed verified record onto the public Observation Log — instantly queryable at /merchant/{domain}

• onyx_verify_explain

  Diagnose a failing x402 v2 /verify. Decodes a captured X-PAYMENT header, runs 10 rules (decode, schema, network/asset/payTo match, value sufficiency, EIP-3009 timing, signature shape, scheme) against expected paymentRequirements, and returns the FIRST failing rule with a plain-En

• onyx_x402_receipt_verify

  Verify an x402 USDC settlement on Base or Base Sepolia. Given a tx hash, decodes the USDC Transfer log and confirms (or refutes) a claim of the form: 'tx X moved $Y USDC from A to B'. Returns success status, actual decoded values, and a clear discrepancy report if any field doesn
