SendCheck: pre-send verification of any EVM address on one chain (EIP-55 checksum, wallet-vs-contract, outgoing activity, balances, verdict). POST {address, chain}

USE WHEN: An autonomous DeFi agent needs to POST { chain, address } to verify smart contract honeypot traps, owner privileges, and pool liquidity.

Token contract facts for agents on Base. Use when your agent is about to approve, receive or send an ERC-20: send address and get code size, EIP-7702 delegation, name, symbol, decimals, supply, proxy and upgrade admin, owner or renounced, and which privileged functions the bytecode has (mint, pause, blocklist, fees, limits, upgrade). Facts only: no grades, not investment advice. Built and run by W

Analyze a Base wallet address for on-chain wallet due diligence, transaction-history research, and risk triage. Returns native balance, transaction and token-transfer counts, first and last activity, contract status, a heuristic activity score, and risk flags as JSON. Not identity verification or a guarantee that an address is safe.

Checks whether a token contract address is real, matches its claimed symbol, and whether its supply figures match an independent source (CoinGecko) — before trading, coding, or reporting against it. Catches hallucinated/wrong addresses, address-poisoning impersonation, and tokenomics hallucination.

Before your agent onboards, pays, or contracts with a counterparty: screen the name against the U.S. Treasury OFAC sanctions lists (SDN + Consolidated non-SDN, synced every 6h) for $0.01. Benchmarked 114/114 sanctioned names found with zero false positives on a 152-case adversarial corpus of misspellings, word-order swaps, and transliterated aliases. Ranked candidates with confidence 0-100, progra

Ready-to-sign, already-simulated Aero allocate() transaction for an sAERO position: the best split of Base gauges for its size (fees plus incentives, after its own dilution) as unsigned calldata for the Voter, with the cooldown, expected USD per day versus now, and warnings. Handles the contract's rules (full overwrite, exact total, ascending addresses, idle power). Never signs or sends. Base only

Crypto token rug-pull and junk-risk check for Base, Ethereum, BNB Chain, Arbitrum, Polygon, Optimism, Avalanche and Solana. Send a token contract address or Solana mint; get a grade (JUNK, RISKY, CAUTION, CLEAN), a 0-100 risk score and red flags: honeypot, sell tax, mint/freeze authority, owner powers, holder concentration, liquidity, pool age. Not financial advice. Free sample: https://nojunk-tok

Current summary row for one Robinhood tokenized-stock token: total supply, treasury balance, multiplier, and whether the queried address is a known look-alike of a tracked token. Identify by ticker or exact contract address. On-chain observations reconstructed from chain event logs, not financial advice.

Creates a five-minute inbound SMS lease through a configured licensed provider, polls received messages, and releases the number upstream on cancellation, expiry or failed x402 settlement. Twilio is supported directly; an HTTPS bearer-token lease provider can also implement the documented generic contract. Messages and lease metadata are removed after expiry.

Automated data-pipeline integrity gate for ETL regression detection and breaking CSV/schema changes. Compares profiles, data-quality deltas, and data contracts, then returns an evidence-backed PASS/WARN/FAIL pipeline action.

Token safety scanner for Base (JSON body): 0-100 safety score, risk band, and red flags for any Base token contract.

A deterministic Base chain identity and official USDC contract-presence check. No request body. Not a token-risk report, transaction simulation, or payment proof.
