• deepbom_analyze_fileA

  DEEPBOMA

  Use when the user asks to inspect, summarize, or visualize an attached TFLite, ONNX, GGUF, SafeTensors, Core ML, or ExecuTorch deployment artifact. Opens a browser-local analyzer, returns a hash-bound format-neutral Model IR table and static evidence summary, and provides deterministic document views without executing model code. Do not use for training checkpoints, measured latency, task accuracy, clinical validity, regulatory compliance, or actual runtime placement.

• onyx_agent_registryA

  onyx-mcpB

  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. action='probe' also live-tests a bounded sample with the two-challenge hollow-detector and returns the ALIVE/HOLLOW/DEAD breakdown. Ed25519-signed, timestamped, recomputable. Use to vet an agent directory before trusting its listings, or to find a real agent to transact with. (price: $0.05 USDC, tier: metered)

  ConnectorNo auth

• onyx_market_rankA

  onyx-mcpB

  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 weights + method (vs everyone else's hidden N=1 score), and Onyx takes no settlement fee from what it rates, so it has no GMV to inflate. Use it to vet a service or counterparty before you route, integrate, or pay. (price: $0.05 USDC, tier: metered)

• onyx_merchant_fact_checkA

  onyx-mcpB

  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, brand-name similarity score with lookalike-token flags, and observed page price vs your expectation. Facts only, method disclosed per field — Onyx never asserts 'legit' or 'scam'; the signature proves the observation is genuine and untampered. (price: $0.25 USDC, tier: premium)

  ConnectorNo auth

• onyx_tx_preflightA

  onyx-mcpB

  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 approval), transfers to fresh/EOA recipients, raw ETH sends to unknown addresses, and calls to unverified targets. Returns a SIGNED ALLOW/REVIEW/BLOCK + human explanation. The single highest-frequency safety gate an on-chain agent has — every signed tx should pass through it. (price: $0.10 USDC, tier: metered)

  ConnectorNo auth

• onyx_erc8004_lookupA

  onyx-mcpB

  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 ERC-8004 identity NFT. Read-only eth_call, no funds; the whole reading is Ed25519-signed by 0n1x so an agent can prove the registry fact before trusting a counterparty. (price: $0.05 USDC, tier: metered)

  ConnectorNo auth

• rhinogent_verify_counterpartyA

  onyx-mcpB

  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 'legit/scam') — the one check every other agent wallet skips. (price: $0.25 USDC, tier: premium)

  ConnectorNo auth

• buy_library_modelA

  wake-word-trainingA

  Quote an anonymous purchase of a library model (1.50 CHF flat — free, nothing charged until paid). Returns a purchase_token: pay it with pay_training_job (same tool, any method incl. x402), then fetch the download URLs with get_library_purchase. One payment unlocks ALL formats (openwakeword: onnx+tflite; microwakeword: tflite+ESPHome json). Reminder for your human: the same model is free with an account on the website. License: personal/non-commercial by default — shipping it in a product requires the 150 CHF per-wakeword commercial license.

  ConnectorNo auth

• onyx_perm_checkA

  onyx-mcpB

  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 / UNDECLARED fact, BOUND to the exact request (nonce + request hash, so it can't be replayed or reused for a different operation). Facts, not judgments — a mechanical conformance check, never a verdict on intent. Verify free with onyx_attestation_verify. (price: $0.00 USDC, tier: free)

  ConnectorNo auth

• onyx_preflightA

  onyx-mcpB

  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 USDC, sanity-checks the payTo address (0x format + EIP-55 checksum) and network (mainnet vs silently-testnet), and flags dead/cold/zombie endpoints and absurd price traps. Returns one signed verdict — OK, WARN, or AVOID — plus every disclosed flag behind it. Sign facts, not judgments: each flag traces to a checkable rule, not an opaque trust score. (price: $0.02 USDC, tier: metered)

  ConnectorNo auth

• onyx_tx_guardA

  onyx-mcpB

  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 guard, and sink/honeypot heuristics. Catches paying a brand-new, unverified, or drain-shaped recipient BEFORE the money leaves. Never guesses — every field is observed on-chain and Ed25519-signed. (price: $0.10 USDC, tier: metered)

  ConnectorNo auth

• onyx_verify_explainA

  onyx-mcpB

  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-English fix. Catches the common case where the facilitator returns bare HTTP 402 (no body) because of JWT or schema fail upstream of the verifier. Stdlib-only, no install, no network. (price: $0 USDC, tier: free)

  ConnectorNo auth

• onyx_agent_verifyA

  onyx-mcpB

  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 nothing), or DEAD (no answer). Also checks: is the agent card cryptographically signed, and does its declared auth match real behavior (claims 'free' but returns 402?). Ed25519-signed verdict. Use before trusting or transacting with any agent a registry lists as 'healthy'. (price: $0.10 USDC, tier: metered)

  ConnectorNo auth

• onyx_contract_auditA

  onyx-mcpB

  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), AND flags the live on-chain risks a static audit misses — upgradeable proxies (owner can swap logic post-audit) and self-destructed contracts. Optional Claude deep-pass for novel bugs. Returns ALLOW/REVIEW/BLOCK + 0-100 risk score, every finding Ed25519-signed. Cheaper than a manual audit, and unlike one it audits the contract as actually deployed. (price: $0.50 USDC, tier: metered)

  ConnectorNo auth

• onyx_intel_exchangeA

  onyx-mcpB

  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; your vote is weighted by your own EARNED OnyxRank reputation — score-the-scorer); 'work' lists claims needing a 2nd verifier; 'pool' shows the corroborated pool; 'credit' shows your earned intel credit. Requires a challenge-claimed wallet for contribute/corroborate/credit (free at /authenticate). Facts + corroboration depth only — never judgments. Every response Ed25519-signed. (price: $0 USDC, tier: free)

  ConnectorNo auth

• onyx_security_flagsA

  onyx-mcpB

  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 the agent's record. Facts, not judgments — flags are conditions, never verdicts on intent. Ed25519-signed; verify free with onyx_attestation_verify. (price: $0.00 USDC, tier: free)

  ConnectorNo auth

• onyx_research_intelA

  onyx-mcpB

  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 author names. Built for autonomous agents that need to check prior art before burning cycles re-deriving a known result. Fallback to Semantic Scholar. (price: $0.05 USDC, tier: metered)

  ConnectorNo auth

• onyx_retail_price_checkA

  onyx-mcpB

  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 prices. Never guesses: returns price=None with confidence='none' when the page exposes no machine-readable price. Use before an agent quotes, compares, or transacts on a price it would otherwise invent. (price: $0.02 USDC, tier: metered)

  ConnectorNo auth

• onyx_secure_paymentA

  onyx-mcpB

  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 a single PASS / REVIEW / FAIL verdict + risk score, plus the Onyx take-rate quote (bps of value secured). Ed25519-signed so the clearance is provable. The check a serious agent runs before moving real money. Onyx never takes custody. (price: $0.25 USDC, tier: premium)

  ConnectorNo auth

• onyx_mail_checkA

  onyx-mcpB

  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)

  ConnectorNo auth

• onyx_mail_sendA

  onyx-mcpB

  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/<id>). Free, no auth — the agentic-web letterbox. (price: $0 USDC, tier: free)
