Resolve one NFT (contract + tokenId) into normalized metadata: name, description, image, attributes and token standard (ERC-721 or ERC-1155). Reads the on-chain tokenURI/uri, then fetches and normalizes the metadata document (ipfs/ar/http/data), rewriting ipfs image links to a gateway URL. Returns `found:false` for non-NFT contracts. Live reads with automatic endpoint fallback.

One-call on-chain analytics digest: biggest protocol TVL shifts (with $ amounts), trending tokens, and a recent-exploit overlay JOINED to the TVL movers (a bleeding protocol gets tagged with a matching hack). Packaged report, not raw side-by-side lists.

Tickers supported by the historical /prices endpoint.

Blockchain TVL overview — all 469+ chains ranked by total value locked with token symbol and chain ID (DeFiLlama).

Scan source code or configuration text for hardcoded secrets: AWS access keys, GitHub/Slack/Google tokens, Stripe and OpenAI keys, PEM private-key blocks, JWTs and high-entropy secret assignments. Placeholder values are filtered out. Each finding gives the rule, a severity (critical/high/medium/low), line and column, entropy and a masked excerpt. Offline and deterministic.

Generate high-quality images and designs from a text prompt via DALL-E 3. Multiple sizes, standard or HD, in one call. Pay per call with USDC (x402) or credits - archtools.dev

Live ERC-20 metadata read directly from the contract: name, symbol, decimals and total supply (raw + decimal-formatted). Handles both string and legacy bytes32 name/symbol encodings. Returns `isToken:false` for EOAs or non-token contracts. Reads live on-chain data with automatic endpoint fallback.

Native ETH / wallet balance for an address on any EVM chain: native balance (wei + ether), transaction count (nonce), and whether it's a contract or an externally-owned account (with deployed code size). Reads live on-chain data with automatic endpoint fallback.

Raw AMM pool state for a pair on BSC / BNB Chain: v2 reserves and v3 concentrated liquidity across PancakeSwap v2/v3, Biswap, ApeSwap. Returns pools[] with venue, surface, feeBps, reserveA, reserveB, price and tvlUsd at a stated blockNumber. Requires ?pair=SYM/SYM (e.g. WBNB/USDT). Errors: 400 bad_pair, 404 no_pools, 502 upstream_read_failed. For USD depth already computed use /liquidity. This is the underlying numbers. Bare = BSC; also /polygon /arbitrum /avalanche /optimism /base.

Live gas price on BNB Chain, Polygon, Arbitrum, Base, Avalanche and Optimism, converted to USD and ranked cheapest-first. Gwei is NOT comparable across chains because the gas token differs in price; USD is the only honest ranking. Returns chains[] with gasPriceGwei, baseFeeGwei, nativeUsd and costUsd for transfer, erc20Transfer and swap, plus cheapest and mostExpensive. Optional ?chain=all or one chain key; 400 unknown_chain otherwise. Send chain=all - a bare call skips the free tier.
