Security x402 offerings

Pre-transaction counterparty check for an EVM wallet or contract: OFAC SDN screening, GoPlus malicious-address flags (phishing, drainers, laundering, mixers ...), and a live on-chain profile (EOA / contract / EIP-7702, nonce, balance, ENS, first transaction, contract verification). Returns risk_level, a plain recommendation (do_not_transact / review_before_transacting / no_red_flags_found), every reason with its source, and which sources were unavailable.

Look up the published record of a software vulnerability by its CVE identifier.

Live scored geopolitical threat feed: name, category, severity, coordinates, and source URL for every active tracked threat.

Verify EVM signatures offline: EIP-191 personal messages, EIP-712 typed data, and x402/EIP-3009 payment authorizations (paste a raw Payment-Signature header) — recovers the signing wallet, checks it …

Validate exact UTF-8 SHA-256 hashes for up to 64 public or synthetic passages. No Unicode normalization, source authentication, or semantic validation. New modular adapter: retained result recovery f…

Review permission changes before an agent release. Compare two explicit allow-only sets by tool, action and exact resource; report additions, removals and wildcard additions. Does not resolve IAM inh…

Verify a bounded civic-ledger-1 public organizational decision suffix against declared checkpoints, including expected-head truncation detection. No Merkle proof or anchor. New modular adapter: retai…

Validate exact UTF-8 SHA-256 hashes for up to 64 public or synthetic passages. No Unicode normalization, source authentication, or semantic validation.

Check citation metadata before an evidence review. Compare up to 20 declared source identities, revisions and locators; return exact mismatches and an integrity receipt. No source retrieval, passage-…

Check declared publication views before release. Compare 2-8 article, registry and API views against canonical URL, content, release and source-set digests; flag stale, withdrawn or substituted views…

Check declared citation coverage of up to 64 claims against bounded source and locator inventories. Reject duplicate IDs and dangling references. Coverage is structural, not proof that a source suppo…

Exact full-release and section hashes plus deterministic bounded line changes for explicitly licensed original Maha section versions; no semantic equivalence claim.

Prepare an inspectable context-selection evidence pack from caller-supplied documents and labelled spans. Combines budget comparisons, retention checks and policy-bound receipts. Verification concerns the declared workflow, not factual truth, answer quality or legal compliance.

Build a stable hashed manifest of bounded public/synthetic artifact contents, declared dependencies, algorithm version, seed, and parameters. Verify declared content hashes; reject duplicate/dangling…

Inspect up to 80 declared attempt records for nonce reuse across intents, changed inputs under one idempotency key, duplicate settlements and ambiguous outcomes. No raw payloads or credentials; no live state access, automatic retry or payment authorization.

Check declared design hash, assay identity, evidence records and control gaps for a research handoff. Does not validate the design, sequence or biological efficacy.

Verify one Ed25519 signature over up to 8,000 characters of exact UTF-8 receipt text using a supplied 32-byte public key. Returns cryptographic validity and message hash. Does not establish issuer id…
