EVM Tx Type Classify: EVM Tx Type Classify classifies legacy, access-list, dynamic-fee, and blob transaction type codes from bounded caller-supplied values without an external provider. Call EVM Tx Type Classify before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Tx Type Classify as versioned deterministic JSON. Price:…

Validate Bitcoin-base58 alphabet membership for local address hygiene — call when checking Bitcoin-base58 alphabet membership locally. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip,…

Returns the current fee rates for the usual confirmation targets together with the state of the mempool behind them, and then does the part that is usually missing: it estimates the virtual size of the transaction you describe and computes the resulting total fee in satoshis for each target.

Attested pre-transaction counterparty check for any Base/EVM wallet: exact match against OFAC SDN digital-currency addresses, on-chain profile, and a transparent clear/caution/flagged verdict with reasons — ML-DSA-65 signed and Hedera-anchored.

Insider tracking on new launches: which wallets entered before the crowd, how early, and what that pattern historically preceded.

Premium bundle on large holders: whale movements, smart-money directory, institutional flow and the alerts that fired, assembled into one dossier.

Render a URL in a real headless browser (JavaScript executed) and return its article content with the clutter stripped — same cleaning + output formats as /api/url/clean, but for client-rendered / SPA pages whose content only appears after JS runs (where a raw HTTP fetch returns an empty shell). `format`: markdown (default), text, both (JSON envelope), html (self-contained reader page, raw text/html), or pdf (typeset reading doc, raw application/pdf). Optional `waitUntil` (load|domcontentloaded|networkidle0|networkidle2, default networkidle2) and `timeoutMs` (1000-15000, default 12000) control how long to let JS settle. Use /api/url/clean instead for server-rendered pages — it is faster and cheaper; only reach for render when JS rendering is required.

The Operator's Statement. REQUIRES ?wallet= on the paid request — a signed request without it is refused before the gate and no money moves. A statement id and a permanent history URL, readable immediately and filling in four times a day for 30 days: one signed pass per read carrying its exact block range, chain head, inflows and outflows with counts and totals, and a per-pass tally of who paid (capped and saying so); a summary derived at read with distinct payers, the large…

Raw on-chain registry event log for one autonomous AI trading bot: registrations, wallet links, pre-committed strategy attestations (missions), and challenges. The verifiable audit trail behind a bot's track record.

Verifiable call log: every signal this desk has published, timestamped and countable (?asset=BTC optional). Audit us for a penny before you spend a dime — no accuracy claims, compute your own. Descriptive research, not financial advice.

Wallet funding QR for your human: pass asset (usdc-base, tao, eth, sol, btc, ...), amount and destination wallet - get a prefilled Apple-Pay-capable onramp link (MoonPay) plus the QR as base64 PNG, ready to forward. Provider minimums enforced, address format validated. The purchase settles directly with the licensed onramp; this service never touches funds.

Implied signals replicated from standout wallets: what they are accumulating or distributing, inferred from settled on-chain flow.

Actionable GBLIN treasury recommendation (invest/hold/reduce/defer) with confidence score and suggested allocation percentage, driven by live on-chain Crash Shield state on Base. Combines Chainlink price risk, treasury analytics and drawdown regime into one decision an agent can act on.

Will this transaction go through? Six checks before any gas is spent: gas vs balance, full simulation with the revert reason decoded, stuck nonces, contract or wallet recipient, ERC-20 allowance, and a sanctions screen of the counterparty. Returns send / do not send with every reason.

Screen an EVM wallet or contract address BEFORE paying it. Deterministic, keyless compliance / safety gate: checks the address against the OFAC sanctioned crypto-address list and a curated taint set (mixer, hack, scam) and returns a single BLOCK / REVIEW / ALLOW recommendation plus the matched sources, so an AI agent can decide whether to send funds. No API keys, no LLM, one x402 USDC micropayment per call.

Check the status of a Base transaction: success/reverted/pending, confirmations, gas used, and explorer link — settlement verification for agents and payment flows.

Returns a bounded relationship graph. Endpoint nodes carry dated route metadata and monetary summaries. Wallet nodes carry Boon OAuth identities when available. Edges distinguish routed recognition, signer-verified subjective reviews, and s

Institutional wallet directory joined with real on-chain holders via Helius, plus the tracking method used, so the result is auditable rather than a black box.

Large on-chain USDC/SOL movements watchlist with the wallets involved. Follow smart money flow as it settles.

Recent material public-source changes for tracked Bitcoin services.

Screen a crypto wallet address against the OFAC SDN sanctions list (US Treasury Specially Designated Nationals) before transacting. Multi-chain across ~20 assets (BTC, ETH, USDT, TRX, XMR and more); EVM 0x addresses match case-insensitively. Returns whether the address is sanctioned plus the listed entity, asset and list publish date. Clean address returns `sanctioned:false`. Public-domain OFAC data.

Base transaction lookup by hash: sender, recipient, ETH value, block, success or failure, gas used and log count, with the receipt folded in, live from Base mainnet. Use it to confirm a payment or transfer landed on-chain. Input: hash (the 0x transaction hash). For the raw receipt use chain.rpc.

Signed multi-chain OFAC SDN address screening (USDC on Base or Solana)

Live whale flow: USDC transfers ≥ $5M on Base with labeled counterparties — scanned continuously (freshness follows the RPC provider's limits; the response always states the block scanned to).
