Every ERC-20 + native ETH a Base address holds (Blockscout-indexed, spam-screened) with confidence-gated USD values: usd is null when no reliable price exists- NEVER a fabricated 0. GET /v1/portfolio/{address}.

Live Morpho Blue borrow positions (collateral, debt, health factor, liquidation distance), Morpho vault deposits (APY, earnings), Gains Network open leveraged trades (pair, direction, leverage, entry, TP/SL), and on-chain PENDING orders (incl. stranded market orders the keyless backend hides) for any Base address. GET /v1/positions/{address}.

Aggregate trading scorecard for any Base address from its closed leverage history: trades, wins/losses, win rate, net USD, gross profit / loss, profit factor, mean R-multiple expectancy, avg win / loss, best / worst trade. GET /v1/stats/{address}. The "am I actually good" read- and the input to a risk-sizing agent.

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/oracle-key.json

HTML to markdown. $0.002 USDC.

The verified ABI of a smart contract on any EVM chain from Sourcify: function signatures, event names, contract name, compiler version and proxy implementations, plus the full ABI JSON ready for a client. Query: ?address=0x8335…&chain_id=8453

Balance and activity for a Bitcoin address (base58 1…/3… or bech32 bc1…): confirmed balance (sats and BTC), total received and sent, confirmed transaction count, and unconfirmed/pending value and tx count from the mempool. On-chain ground truth an agent cannot compute locally.

US stock sentiment 24/7, including nights and weekends: trade flow of tokenized US equities and ETFs (NVDA, AAPL, TSLA, SPY, ...) labelled with the current US market session, with breadth, average buy pressure and per-asset signals. Use to read stocks when exchanges are closed.

Known security advisories for a package from OSV, with severity and the versions that fix each one. Pass version to narrow to one release.

ERC-20 token metadata and total supply by contract. Given a chain and a token contract address returns name, symbol, decimals and total supply (raw + decimal), read live on-chain. For token explorers, due-diligence, supply-tracking and DeFi agents.

On-chain ERC-20 token balance for a wallet. Given a chain, a wallet address and a token contract address returns the token balance (exact raw units + decimal), with token name, symbol and decimals, read live from the chain. For wallet trackers, DeFi portfolio valuation, airdrop checks and treasury-monitoring agents.

On-chain native coin balance for any wallet. Given a chain (ethereum, base, arbitrum, optimism, polygon, bsc) and a wallet address returns the native balance (ETH/MATIC/BNB) in both exact wei and human-readable decimal, with symbol and decimals. Read live from the chain via RPC. For wallet trackers, portfolio, treasury-monitoring and payment-verification agents.

Deterministic risk screen of an ERC-20 token from on-chain bytecode and metadata, no third-party risk API. Flags privileged or abuse capabilities: blacklist/freeze, owner mint, pausable transfers, upgradeable proxy and a privileged owner, plus tokens missing symbol/decimals or code. Returns each flag with a severity, a 0-100 score and a verdict. Reads live on-chain data with automatic endpoint fallback.

Live snapshot of the Bitcoin mempool: number of unconfirmed transactions, total pending virtual size (bytes and MB), the current backlog in blocks, total fees pending (sats and BTC), the fee-rate histogram, and the current chain tip height. Lets an agent gauge network congestion and time a transaction.

Live recommended Bitcoin transaction fee rates (in sat/vB) for next-block, ~30-minute, ~1-hour, economy and minimum confirmation targets, straight from the mempool. Also estimates the total fee (in sats and BTC) for a transaction of the given virtual size, so an agent can pick a fee tier and know the cost before broadcasting.

Scan supplied code with transparent deterministic rules for common secret, injection, shell, weak-hash, and Solidity risks. This is not a professional audit.

Read the current eth_gasPrice value from a supported public Base, Ethereum, or Arbitrum JSON-RPC endpoint.

Chain-of-custody license certificate for any digital asset: a SHA-256 content hash bound to issuer, subject, and license terms under an HMAC-SHA-256 signature. Deterministic, portable, and verifiable through the issuer while the current HMAC v1 profile is active — a receipt an agent can carry to record what it licensed, from whom, and on what terms.

Ephemeral Postgres for agents: one POST provisions a real database and returns its connection string with a TTL; teardown at expiry is automatic and guaranteed. Scratch space for a pipeline, a test run, or a day of work — priced per DB-day, no signup, no cleanup, no leftovers.

Weigh any x402 counter and get a verdict: does its URL answer a coherent 402, would the CDP Bazaar validator accept its discovery metadata, and is it actually listed in the discovery index? Returns a per-check report (passed / found-wanting / unweighed) with evidence, optionally HMAC-signed. Three keyless checks for sellers and machine-service buyers.

Current gas price + base fee for a chain, with an ERC20-transfer cost estimate.
