Bitcoin mempool stats + recommended fee rates (sat/vB) from mempool.space. Block height, pending tx count, fastest/30min/1hr/economy fees.

What has this token done over the last N days? Up to 365 days of OHLCV returned candlestick-ready, with the period price change already computed — a chart or backtest input in one call instead of a raw series you have to align and diff yourself.

GitHub developer activity for any crypto project — commits, stars, forks, PRs, code additions/deletions via CoinGecko.

Smart contract security audit, solidity vulnerability scan. 11 static patterns: reentrancy, access-control, integer-overflow, unvalidated-call, tx.origin auth, delegatecall, selfdestruct, block.timestamp, weak-randomness, assert misuse, owner-change. Fast pre-check, deterministic. Case: minia2a.uk/blog/blog-ai-contract-audit-august-2026.html

Detect material state changes in NAV, income, maturity, redemption and freezes

Get the connected wallet and vault info across all networks

Lido staking: stETH supply, APR and validator/queue state.

Exchange rate between two ISO currencies (ECB reference rates), optionally converting an amount.

Agent payments have no chargeback. Paddock is pre-payment verification for AI agents. get_changes diffs today against any snapshot up to 90 days back: new sellers, retired sellers, category share shifts and top movers.

Measure live, aggregate commerce activity across this marketplace's payment rails, including volume, success rates, and task-state breakdowns by rail and time window. Privacy-preserving by design: no buyer wallet, transaction hash, Lightning node id, or individual payment record is returned.

Read one wallet or contract's current ERC-20 balance directly from Base, Ethereum, or Arbitrum, including raw units and contract-supplied token metadata.

Read an address's native balance directly from Base, Ethereum, or Arbitrum at a selected block tag or height.

Asia-session crypto market snapshot for AI agents: kimchi premium, funding-rate regime signal, and BTC/ETH Asia-hours momentum from a live 24/7 trading system.

Has the sanctions feed moved since you last looked? Every OFAC designation and delisting since a timestamp you supply, with no address list to send — match the feed against your own counterparty book locally, so the service never learns which addresses are yours. The trivial cron: poll this, pass the returned checkedAt back as `since`. Free alternative: GET /v1/watch. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.

Returns current blockchain information including chain height, difficulty, and network statistics.

Verify a hash-linked agent commerce journey and issue a signed portable receipt

Smart contract security audit, solidity/rust/move vulnerability scan. AI deep audit across chains — 3x sampled, deduplicated. Catches business-logic, economic, cross-contract flaws (uninitialized owner, account confusion, missing signer auth). LIMITATIONS: AI audit is probabilistic — may miss vulnerabilities or report non-issues; treat as guidance, not proof; critical findings require manual verification. Case: minia2a.uk/blog/blog-ai-contract-audit-august-2026.html

Crypto brief in one call: coin prices (optional), fear-and-greed index and gas. Provide optional coins list (default bitcoin,ethereum).

Current block number and gas price for Base and Polygon mainnet, fetched live via RPC on every call. Unlike this catalogue's corpus-search listings, this makes a real outbound network call on purchase -- freshness is the product, not a stored snapshot.

Identify an address: EOA vs contract, token standard (ERC20/721/1155), proxy, metadata.
