Pre-payment honesty screen for any x402 endpoint. Run BEFORE paying: probes the target URL unpaid, parses its 402 challenge, cross-checks price against its /.well-known/x402 manifest and the CDP Bazaar listing, and sanity-checks the payTo wallet on-chain. Returns reachable, challenge validity, price, payTo, Bazaar match, risk flags, and a 0-100 honesty score. Public data only; no bulk dataset.

Payer dossier for one wallet over the indexed window: label (organic / operator / self-test / unseen) with evidence, USDC spent, purchases, sellers paid, facilitators used, cadence class, active days, top-5 basket and the operator cluster if there is one.

Read-only EVM state API for wallet snapshots, ERC-20 balances, token allowances, contract code, block heights, and bounded eth_call reads across Ethereum, Base, Arbitrum, Optimism, and Polygon. Fixed price: $0.15 USDC on Base for a batch of up to 100 checks. Only submitted checks run. Results are provider-reported RPC data, not cryptographic proofs.

Returns trending tokens across the entire blockchain for a specified activity window and optional category. The size of the increase in active wallets over the activity window determines the token's trending rank.

What a seller's payTo address earned from x402 payments on Base in the last days, read from the chain: total, distinct and repeat payers, per day, per price, top payers and recent payments, with plain USDC transfers counted apart and your own test wallets left out on request. Includes the seller's Bazaar listings with their payers, calls and measured uptime.

Check whether an approved Base token swap is eligible before supplying a wallet. Returns verified token contracts, indicative output, liquidity sources, fee estimate, warnings, and the exact next action. No custody, signing, or execution.

Reviewer quality lookup. Returns quality score and review history for a wallet address that has left ERC-8004 feedback.

Bitcoin protocol and software changes as JSON: Bitcoin Core merges and releases, BIP updates, Lightning spec and implementation changes. Each item has status (proposal, merged, released, activated), layer (consensus, policy, p2p, wallet), why it matters, what has not happened yet, and primary source links.

Payment receipt and settlement proof for x402 and agent payments, by Liquid Logic X. Input: a Base USDC tx hash (optional memo). Output: JSON proof recorded onchain on Arc mainnet (proofId, from/to/amount, Arc tx, refId) plus a public verify link anyone can check. $0.02 USDC on Base, charged only when a proof is returned. Your paying wallet must be the tx sender or recipient. Liquid Logic X also r

Settlement canary: returns a timestamped pong JSON after USDC micropayment. Use to verify x402 client + wallet + facilitator end-to-end.

Nooscape pre-flight check on an AI agent in an on-chain registry (ERC-8004, Solana), a wallet that registers agents, or an endpoint host: dated flags for first seen, ownership changes, revoked ratings and fleet, with sources. No score, no verdict.

One combined go/no-go before an agent spends: PROCEED / CAUTION / ABORT from the token's market verdict, the counterparty wallet's sanctions, age and poisoning check, and — with a spender — its ERC-20 approvals. A leg that cannot be evaluated returns unknown and caps the verdict at CAUTION. Mode 'compact' returns the decision, the worst leg, and one summary per leg. Use this when an agent is about

Screen an EVM wallet address by exact match against the digital currency address identifiers on the official US Treasury OFAC SDN List (validated snapshot, refreshed hourly). Returns a signed listed / not_listed result with the SDN entry, dataset provenance and limits. SDN only, not EU/UN/UK lists; a non-match is not legal clearance. For payment screening before sending funds.

Base token risk report with an AI-written plain-English summary. Checks what most scanners miss: whether the creator or launch wallet can pull the pool liquidity (incl.

Due diligence on an ERC-8004 agent before you pay it or call it: live services and their health, metadata completeness, onchain feedback count and score, wallet activity, concrete red flags, and a usable/caution/avoid verdict with a 0-100 score. Call it when you must decide whether another agent is safe to transact with. Params: chain (default 8453) and agent_id (ERC-8004 token id).
