Attested pre-transaction counterparty check: OFAC SDN digital-currency list match plus on-chain profile for any Base address, returned as a signed, Hedera-anchored verdict you can cite as evidence of diligence.

C2PA verdict attestation Tier B. Client runs Credentio locally, submits verdict JSON + asset hash + client signature. Rubric countersigns and anchors receipt. Attests the assertion was made, not verdict truth. Operated by Rubric Protocol.

C2PA verdict attestation Tier A. POST raw asset bytes (max 25MB). Rubric runs Google Credentio validation in-sandbox, anchors the verdict to Hedera with ML-DSA-65 post-quantum signature. Durable proof asset X validated against C2PA Trust List Y at time T. Operated by Rubric Protocol.

Signed monthly x402 spend statement for one agent: totals, per-payment lines, Merkle root. The statement is itself an ML-DSA-65 attestation anchored to Hedera mainnet HCS. Render, verify, and print the response free at https://rubric-protocol.com/statement.html

Rubric scoring — Base-100 series + IQR outlier flags: Base-100 series + IQR outlier flags for supplied rubric scoring records (awarded_points, available_points). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

Rug-risk verdict for a Base ERC20 address: 0-100 score, A-F grade, one-line summary, graded checks (ERC20, honeypot selectors, liquidity, market) plus a separate ungraded adminPowers profile (proxy, owner, mint, blacklist, pause), each with raw evidence. No LLM.

Rug check for any token ($0.01): is this token a rug pull or scam? Short verdict LOW_RISK, CAUTION or HIGH_RISK with a 0-100 safety score, one plain sentence, can it be sold, buy tax, liquidity, owner control and the top three risks, for a contract on Base, Ethereum, Arbitrum, Optimism, Polygon or Solana.

Parallel Solana risk advisor aggregator: one call asks selected independent x402 advisors and returns each answer with an advisor-only consensus. RugShield's code-based flags are separate when available; no flag is not a safety vote. Choose anonymous options with ?advisors=a,b (free list: GET /v1/advisors), or omit to call all. Price = advisor cost + max(US$ 0.005, 15% of advisor cost). No charge if none answer; Base x402 upto charges only for answers.

Solana token rug check for pump.fun tokens before buying (is this token safe / rug pull risk): advisory flags, each with its measured precision. SNIPER_FEE_FINGERPRINT: recent txs paid fees used by known sniper clusters (100% precision, 80 rugs + 80 healthy). FACTORY_DEPLOYER: creator launched 10,000+ tokens with <=2% graduating (88.9% precision). Returns RISK_FLAGS or NO_FLAGS; NO_FLAGS does not mean safe. Input: token mint (base58).

Solana transaction safety check before signing (pre-sign guard, wallet drainer detection). Send the unsigned tx as base64; we simulate it on mainnet and return ALLOW, WARN or BLOCK with exact SOL and token balance changes and why: owner reassigned, unlimited approval, account closed to a third party, Token-2022 permanent delegate, SOL outflow above intent, swap output redirected. Solana only. 1,132 mainnet cases: 100% of attacks blocked, 0.13% false blocks, p95 1.0 s.

RugRadar: Solana rug check and rug pull checker for pump.fun memecoins, plus BNB rug check / BSC honeypot check (four.meme rug check), Base, Ethereum, Arbitrum via chain=. Returns a 0-100 risk score and plain reasons: mint/freeze authority, top-holder concentration, liquidity, token age, deployer history (prior launches that died), funder linked to earlier high-risk patterns. Automated heuristic, may be wrong. Not financial advice. 0.002 USDC/call; failed calls are free.

RugRadar token safety and honeypot check: token scam check and memecoin risk score for Solana (pump.fun), BNB (four.meme), Base, Ethereum, Arbitrum (chain=). Returns a 0-100 risk score with plain reasons: honeypot simulation (EVM), mint/freeze authority, top-holder share, liquidity, age, deployer launches that died, linked funder. Same engine as /rug-check. Automated heuristic, may be wrong. Not financial advice. 0.002 USDC/call; failed calls are free.

RugRadar Watch + Alert: watch one Solana token (pump.fun incl.) for 24h ($0.05) or 48h ($0.10). Re-checked about every 10 min; signed webhook alert when the dev sells, liquidity drops 30%+, mint/freeze authority appears, risk score jumps 20+ points, or it can't be sold. Heuristic, may be wrong. Not financial advice.
