Profile a wallet's activity and label it smart-money (ROI, activity, token set) on Base. Returns a score + top holdings. DO NOT use to solicit investments.

🆕 The 'who am I dealing with?' check for agents. Reads Coinbase's ONCHAIN verification (an EAS attestation by verifications.coinbase.eth) — meaning the address is tied to a KYC'd Coinbase account, the strongest sybil-resistance signal on Base — plus the address's Basename. Returns a verified/named/anonymous verdict + trust score. Pair with sign-guard/spend-audit for a full pre-transaction gate. Identity is a signal, not proof of honesty.

Scan any wallet address for anomalous transaction patterns

Notifies users of large cryptocurrency transactions detected on blockchain networks.

Tracks capital flows from sophisticated investors across blockchain networks.

Individual liquidation events recorded from our own exchange sockets across Binance, Bybit and OKX: side, price, quantity, notional, venue and millisecond timestamp. The daily rollup is free at /api/v1/public/datasets/liquidations-daily.

Recent ON-CHAIN Polymarket trades of one wallet (path param: 0x… proxy-wallet address), EACH wrapped in its own ed25519-SIGNED attestation (kind "onchain-activity"). Honest scope: Polymarket-whale on-chain activity — real Polygon transactions of prediction-market wallets — NOT general ERC-20/DEX crypto intel. Every attested row has a real tx_hash (Kalshi's anonymous prints have no on-chain identity and are excluded by construction). Signed facts per trade: tx_hash + block_time (no block number is stored, none is claimed — derive it from the tx receipt), wallet, condition_id, side, price; size_usd is included but labeled a MODELED USD notional in data_basis. Attestations are minted ONCE per tx_hash and reused (byte-stable signature per transaction), and verify FREE offline at GET /verify against the same published key as every Predge envelope. 15 min delay. Query param: limit (1-50, default 20). 404 (not charged) for a wallet with no on-chain Polymarket trades in the Predge dataset.

The latest transactions for a Base address — hash, time, from/to, ETH value, success — via Covalent. For agents tracking what a wallet is doing.

Returns alerts for newly deployed smart contracts matching specified criteria.

Provides notarization services for Solana blockchain transactions or data.

Decision procedure for an agent whose value is fragmented across systems. Inputs: per-location balance ledger (checkout provider, wallet USDC, card issuer, pay rail), pending spend obligations, per-location withdrawal/swap/bridge fees and minimums, settlement latency, custody risk. Output per obligation: location status (spendable-in-place, withdrawable, trapped), ranked mobility path by all-in cost (direct spend, withdrawal, swap, bridge, card top-up, rail re-route), trigger conditions (idle

Give a Base transaction hash and Claude explains what it actually did in plain English — the action, a risk read (failed tx, risky approval, high-value transfer), and notes. Turns raw calldata into an answer agents and humans can use.

Checks whether a specific wallet is authorized under a B20 token's transfer-sender policy. If it isn't, that wallet can't transfer and can be burnBlocked() (SEIZED) by the issuer. The personal companion to b20-safety — 'can this token freeze MY funds?'

Paid agent-facing brief on wallet-handle authenticity verification: decision procedure for an agent deciding whether a claimed Cloudflare/agent wallet handle is genuinely controlled by the counterparty (signed ownership attestation, reservation proof, staleness rules, typo-squat risk) before agent-to-agent x402 commerce · Build a decision procedure or schema for: wallet-handle authenticity verification: decision procedure f-0. Blunt decision procedure, not marketing.

Selects the applicable payment context when a browser agent pays through a Cloudflare-style wallet with multiple settlement rails, verifies the provider challenge is correctly scoped to that context, and records which provider actually settled the receipt.

Decision procedure for the principal side of the agent-wallet era: verify wallet-to-identity binding before trusting a spend (signature over identity claim, issuer attestation, key custody proof), construct per-wallet spend limits (daily cap, per-merchant cap, category allowance, expiry), and validate cross-wallet delegation chains. Returns PASS/FAIL per gate with explicit rejection reasons.

🆕 The single call before trading a Base-native B20: seize (burnBlocked) + freeze (Policy Registry) + rebase + pause + uncapped-mint, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Pass wallet= to also check if YOUR address is already blocked on that token. The B20 tool to bind first.

Paid agent-facing brief on agent-facing decision procedure for identity-wallet related-address exposure: when to pay for Nansen-style wallet profiling (related addresses, token holdings, entity tags, smart-money labels) versus free onchain indexers, with per-wallet spend caps, freshness gates, label confidence thresholds, and kill criteria · Build a decision procedure or schema for: agent-facing decision procedure for ident. Blunt decision procedure, not marketing.

A deterministic decision procedure for agents managing payment sessions on Nano v2, XRPL x402 facilitator, Algorand, and Base prepaid bearer-token endpoints. Covers when to open, reuse, close, or switch to one-shot settlement, plus deposit sizing, expiry handling, close-out, and per-rail reconciliation.
