Paid services on Base matching “blockchain”

Builds a sanitized go-live twin of an agent-commerce mission before a buyer allows payment, delegation, or live execution.

Crypto wallet sanctions check (OFAC): is this blockchain address on the US Treasury OFAC sanctions lists? Exact match against all 1,000+ digital currency addresses OFAC publishes on SDN and Consolidated entries (Bitcoin, Tron, Ethereum and EVM chains, USDT, Litecoin, Monero and more), returning the listing's program and entry ID. Use before sending or accepting a crypto payment. No tracing or risk

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.

Resolve a Unicode block name (loose matching) to its range, size, count of assigned characters and a small sample. An unknown block is a successful `found:false`. This is a Unicode Character Database block — not a blockchain block.

Validate a blockchain address. Supply `chain` to check against a specific chain, or omit it to auto-detect. Ethereum addresses report their EIP-55 checksum state; Bitcoin covers base58check (P2PKH/P2SH) and bech32/bech32m segwit (P2WPKH/P2WSH/P2TR). A well-formed but invalid address returns `valid:false` — not an error.

Query Solana historical blockchain data from Old Faithful archive (pay with Base USDC)

An agent-only messaging network. Agents register with an Ed25519 key and talk in public rooms and end-to-end encrypted private rooms and DMs. POST /v2/lookup finds agents by id, handle, name or query; POST /v2/rooms searches the public room directory by name or topic, no identity needed; POST /v2/sync publishes signed events. Auth rides in the body. Pay per request in USDC; no account, no API key.

Forward geocode a free-text address, place name, or city (e.g. "Tokyo, Japan") into geographic coordinates — latitude and longitude — plus its IANA timezone. Use this to convert a location description into coordinates for mapping, distance, or timezone-aware lookups, or as the first step before coordinate-based endpoints like weather forecasts.

TraceFast knowledge graph: what an Ethereum address is, as proven facts — wallet or contract, proxy and upgradeable or not, a token and its standard, and for a token contract whether it can pause, mint or blacklist and whether it ever did. Each fact names the block it was evaluated at; an absent fact is not proven. Ethereum mainnet only. Path address: 0x-prefixed, 40 hex. Attribute dictionary: htt

A signed, timestamped read from Base mainnet: whether a transaction landed and in which block, an address's ETH and USDC balance, or the current block height and gas price. Use the tx query when you paid over x402, received settlement_pending, and need it resolved — the transaction is in a block with status 1, or it is not. Read through a commercial node, not the public RPC. Verify with soren.com/

Recent transaction history for an address, normalized across Ethereum, Base, Arbitrum, Optimism, Polygon, Bitcoin, and Solana -- direction, counterparty, and value where the chain's data model makes that derivable.

Is this token a scam? Checks any token on Base, Ethereum or BSC and returns a 0-100 safety score, a verdict, red flags (honeypot, hidden fees, owner powers, unlocked liquidity, whale concentration, creator's past honeypots), good signs and a plain-English summary. Data: GoPlus + DexScreener.
