Every agent-payable API.

Live gas market on any major EVM chain: current gas price, base fee and priority-fee percentiles (p25/p50/p75) in gwei, plus the estimated cost in native token and USD for a plain transfer (21k gas) and a typical DEX swap (200k gas). Lets an agent decide whether a transaction is worth sending right now or should wait for cheaper gas, and budget the fee before signing.

Spot USD price for any crypto asset. Accepts a ticker symbol (eth, btc, sol), a CoinGecko id (ethereum), or an EVM token contract address. Returns the USD price plus 24h change, with market cap for listed assets, or liquidity, 24h volume and the top DEX pair for contract addresses. Cached 60 seconds so repeated calls in one agent workflow stay consistent with each other.

Transaction lookup and decode on any major EVM chain. Turns a raw tx hash into agent-readable facts: success or failure status, block number, sender and recipient, native value transferred, gas used, fee in native token and USD, and every ERC-20 transfer decoded with token symbol, decimals and human-readable amount. Returns found=false for an unknown hash instead of erroring.

ENS name resolution in both directions on Ethereum mainnet. Pass name to resolve an ENS name to its address (forward), or pass address to get that address's primary ENS name (reverse, forward-verified so spoofed reverse records are rejected). Read straight from the ENS registry. Use it to turn vitalik.eth into an address, or to label a raw address with a human-readable name.

Latest block on any major EVM chain: block number, timestamp, age in seconds, base fee and gas used/limit. The cheapest possible liveness and chain-tip check for an agent: confirm a chain is progressing, timestamp an observation, or pick a block for a query.

Run read-only SQL against Coinbase's indexed, DECODED blockchain data - base.events (decoded logs with parameters), base.transactions, base.blocks, base.decoded_user_operations, base.transaction_attributions (builder codes), plus solana.instructions and hyperevm.events. ClickHouse-dialect SELECTs, server-side grammar validation, up to 50k rows / 30s / 12 joins. Ask Base anything - token flows, event analytics, gas studies - in one call, no indexer to run.

Onchain safety verdict for (token): liquidity, pair age, turnover, buy/sell flow — grade GREEN/MID/YELLOW/RED with reasons

Returns a single, verifiable snapshot of any EVM wallet: native balance, ERC-20 token balances, current block number, and recent activity count across the most popular chains (Ethereum, Base, Arbitrum, Polygon). Built for x402 agents that need on-chain facts without managing RPC keys or node infrastructure. Each call returns a deterministic JSON payload with a chain-specific block number at snapshot time so results can be independently verified against a public RPC or block explorer.

Onchain options protocols ranked by 24h notional volume with 7d and 30d volume, 1d and 7d change and the chains each runs on, plus sector totals. Use it when an agent is comparing decentralized options venues or tracking whether onchain options activity is growing.

Reality check on dividend and reflection token yield claims, deterministic. For any tax-redistribution token (gold dividends, USDT rewards, reflections): live 24h DEX volume x tax rate x payout share = the ACTUAL daily reward pool, compared against the promised figure, with a VOLUME-BACKED / STRETCHED / FANTASY verdict and the required-volume multiple. Also flags same-symbol copycat tokens on other chains. No LLM. Pair with /api/evmtoken: contract safety and yield math are different questions.

Bank-reconcilable receipt for any on-chain settlement: turn a transaction hash into an ISO 20022 camt.054-style credit notification (XML + JSON), a deterministic evidence bundle with canonical SHA-256 hashes, and an Ed25519 signature anyone can verify without an API key at /verify.html. Same tx always yields a byte-identical bundle. Covers ERC-20 transfers (incl. x402 USDC settlements) on 11 EVM chains. Params: tx (hash, required), chain (default base), perspective (address).

Holder-concentration map for any token — Solana + 8 EVM chains incl. Base & Robinhood Chain: top holders with LP-pool / locker / burn / contract labels, largest-wallet and top-10 share excluding LP & burn, % of supply in LP or lockers, % burned, % sitting in unlabeled contracts, creator & owner balances, insider-cluster detection (Solana). The "who actually holds this thing" layer of token due diligence, as observable facts with per-wallet breakdown. Deterministic, sub-second, no LLM.

Live USDC yield panel on Base, read DIRECTLY from chain state — Aave v3, Compound v3, Moonwell, Euler v2 supply APY from onchain rate views, plus the six largest Morpho (MetaMorpho) USDC vaults with REALIZED trailing APY from ERC-4626 share-price deltas (archive reads, net of fees — not a vendor estimate). Optional: any custom ERC-4626 vault address on Base. Built for yield agents (Sail/Sailor, rebalancers, treasury bots) that need verify-before-acting numbers.

Exit-depth / sell-impact estimator for Uniswap-v3-compatible AND v2-style (x·y=k) pools on 11 chains (Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, Avalanche, Monad, World Chain, HyperEVM, Robinhood Chain): live pool state read from the contract (v3 sqrtPrice + in-range liquidity, or v2 reserves); tokens sellable at 1/2/5/10/25% price impact in tokens, quote and USD, %-of-supply framing, manipulated-liquidity cross-check vs DexScreener. Deterministic pool math, no LLM — the "can I actually g

Rug & token-safety scanner for Algorand ASAs — the first automated pre-trade check on the chain. Reads the AVM rug surface directly (clawback/freeze/manager authorities, default-frozen honeypot flag, reserve overhang), whale & creator concentration with DEX-pool accounts split out, Pera & Tinyman verification tiers, and live Tinyman liquidity/volume — fused into one deterministic CLEAR / CAUTION / AVOID verdict. Answers: is this token safe to buy?

Token safety check — answers "is this token safe to buy?" for any token: one deterministic CLEAR / CAUTION / AVOID rug & honeypot verdict across 10 chains (Solana, Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, Avalanche, Robinhood Chain, Algorand). Auto-detects the chain from the address shape. Sell-simulation honeypot, mint/freeze/clawback authority, LP lock/burn, holder concentration, live liquidity — fused into one verdict. Pre-swap guardrail for trading agents and agent wallets.

Structured checks, checks-passed count, explorer citations, no scores, no advice. Solana + 8 EVM chains.

Narrative-vs-chain consistency check — the missing layer of token due diligence: fetches the project's own website, extracts its checkable public claims (supply, locks, team holdings, taxes, ownership) and marks each one consistent / inconsistent / unverifiable against independently observed on-chain data, with the exact numbers. Pre-launch-imposter screen included (site live? trading while site dead?). Solana + 8 EVM chains incl. Base & Robinhood Chain. Facts only — no scores, no advice.
