Every agent-payable API.

Solana balance. SOL balance of a Solana wallet, read live from mainnet in lamports and SOL, plus its SPL token accounts (mint, symbol for well-known tokens, decimals, amount) when the public node serves them; otherwise tokens is null with a note. Use to check a Solana wallet before a payment. An address that is not 32-byte base58 is 400, uncharged.

Solana epoch progress — Genesis402 / UnyKorn Operator Network

Solana / pump.fun token rug screen (OK / CAUTION / AVOID) for $0.01: mint and freeze authority, bonding-curve launch share, creator holdings, top-10 share, liquidity, age, flow, DexScreener paid-boost flag. Pass a mint.

Executable swap quote on Solana from Jupiter's aggregator: input and output mint, amount in base units, slippage in bps - returns out amount, minimum out after slippage, price impact percent, the routed DEX labels in hop order with split percentages, the USD value of the swap and the context slot. A real multi-hop route across Solana DEX liquidity, so the number reflects depth, not a spot price. Quote only - nothing is signed or sent. Keyless.

Hand over a Solana SPL mint address and get one cited due-diligence brief: what the token is, whether the mint and freeze authorities are still live, how deep and how locked the liquidity is (pools, lockers, unlock dates, DEX pairs, 24h volume and buy/sell balance), who holds it (top holders with pool and locker accounts told apart from wallets, concentration with and without pools), and every named risk flag the public feeds carry, plus what this data cannot see.

Top-holder concentration for a Solana token mint: the 20 largest holders with token account, owner wallet, balance, percent of supply, insider flag and a pool/locker label when the account is a known AMM vault or locker, plus top-1/5/10/20 share, top-10 share excluding labelled pool accounts, insider count, total holder count and supply. Use it to tell a whale-held launch from one whose largest holder is the liquidity pool.

Solana token info. Look up a Solana SPL token by its mint address, live from mainnet: decimals, total supply, whether a mint authority can still create more and whether a freeze authority can freeze holders (two common rug-pull risks), the token program, and, on request, the largest holder accounts with their share of supply. Use before buying or accepting an unknown Solana token. A mint that does not exist is 404, uncharged.

Resolve a Solana token by mint, ticker or name through Jupiter's token index and get its profile in one read: name, symbol, decimals, price, market cap, FDV, liquidity, holder count, circulating and total supply, verified flag, organic score (Jupiter's wash-trade-resistant activity score), tags, launchpad, dev wallet, first pool and date, audit facts (mint and freeze authority disabled, top-holder share, dev mints) and 24h stats (price, holder and liquidity change, buy/sell volume, traders, net.

USD price for up to 50 Solana token mints in one call from Jupiter's price API v3: price, 24h change, liquidity, decimals and the block the price was read at. Mints Jupiter does not price come back listed under missing rather than erroring the batch. Pass mint addresses, not tickers (resolve tickers with sol-token-search or sol-token-lookup). Keyless.

Full RugCheck report for a Solana token mint, trimmed to what an agent acts on: score and risks, mint/freeze authority state, metadata mutability and update authority, supply and decimals, creator and creator balance, top 20 holders with percent, owner, insider flag and pool/locker labels, concentration totals, the deepest markets (liquidity, LP locked %), lockers, total market liquidity, LP providers, holder count, rugged flag, insider-network count, launchpad and transfer-fee config.

Safety verdict for one Solana token mint: a graded risk score with the concrete reasons behind it, mint and freeze authority state, how much of the liquidity pool is locked, top-holder concentration, holder count and whether the token is verified. Use it before an agent buys, quotes, or recommends an unfamiliar token, and to screen a list of mints in seconds.

Every DEX pair trading a Solana token mint (Raydium, Orca, Meteora, Pump.fun AMM and the rest), sorted by liquidity: pair address, DEX, price in USD and in the quote token, liquidity, FDV and market cap, 5m/1h/6h/24h volume and price change, buy/sell transaction counts, pair age in hours, plus totals across pairs. One DexScreener request, keyless.

Sonic (S) price in USD now, with 24h and 7d change — Genesis402 / UnyKorn Operator Network

Sonic ERC-20 balance. ERC-20 token balance of a wallet on Sonic (USDC, USDT, WETH or any token, via balanceOf): raw amount, decimals, symbol and the human-readable amount, live from the token contract. Use to check stablecoin or token holdings before a transfer or trade; for the native coin use sonic_balance. Both inputs are 0x addresses (40 hex characters); no contract returns 404 and a non-ERC-20 contract 422, both uncharged.

Sonic ERC-20 token info. Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Sonic, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use sonic_token_balance. Input is a ticker (USDC, WETH…) or the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged.

Sonic account nonce. Read the transaction count (nonce) of a 0x address on Sonic, both confirmed and including pending transactions. Use to build the next transaction or to tell whether an address has ever sent anything; for its balance use sonic_balance. A malformed address is rejected with 400, uncharged.

Sonic contract check. Check whether a 0x address on Sonic is a smart contract or a plain wallet: bytecode size, and whether it is an EIP-1167 minimal proxy and which implementation it points to. Use before sending funds or approving a spender; for a fuller risk verdict use check_counterparty. A malformed address is rejected with 400, uncharged.

Sonic gas price. Current gas price on Sonic (eth_gasPrice): gas price, base fee and suggested priority fee in gwei, plus what a plain S transfer (21,000 gas) costs right now. Takes no input. Use before sending a transaction or to decide whether to wait; for the fee a past transaction actually paid use sonic_receipt.

Sonic native balance. Native S balance (eth_getBalance) of any 0x wallet address on Sonic at the latest block, in wei and in S. Use to check whether a wallet can pay gas or a transfer; for ERC-20 tokens use sonic_token_balance, for all holdings at once use wallet_portfolio. A malformed address is rejected with 400, uncharged.

Sonic recent event logs. Recent contract event logs on Sonic (eth_getLogs): the events a contract emitted over the last N blocks (1-1,000, default 50), optionally filtered by topic0 (the 0x 32-byte event signature hash). Returns up to 100 logs with block, transaction hash and topics. Use to watch transfers or contract events; for one transaction's outcome use sonic_receipt.

Sonic transaction. Look up a Sonic transaction by hash: sender, recipient, value in S, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use sonic_receipt, for emitted events sonic_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged.

Sonic transaction receipt. Transaction receipt on Sonic (eth_getTransactionReceipt): success or reverted, gas used, effective gas price, fee paid in S, number of event logs and any contract created. Use to confirm a payment or call went through; for sender, value and calldata use sonic_tx. Input is a 0x-prefixed 64-hex hash; a pending or unknown hash returns 404, uncharged.

Sonny Boy — Samson retelling in Hawaii for understanding betrayal, transformation, and redemption arcs.

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

Giveaways already announced but not yet claimable, with the exact date each becomes free and what it normally costs. Forward-looking information no training data can contain. Currently Epic Games Store only — no other storefront publishes a schedule.

Every PC game currently free to KEEP (claim once, own permanently) across Steam, Epic Games Store, GOG and itch.io. Each entry verified against that store's own API before publication. Per-store status distinguishes "verified: nothing is free" from "could not check", so a zero is a fact rather than an absence of data. Self-verifying: the version field is a SHA-256 of the payload's own content.

A heartbeat that costs money, and therefore proves more than a health check: not merely that the server answers, but that x402 verification and settlement are working right now, end to end. Suitable for a monitor that needs to know the PAID path is alive.

Live web search for agents: up to 10 results with title, URL and snippet. Use it when your agent needs to find current pages and has a wallet instead of a search API key. Charged ONLY if the search succeeds. Results pair with /v1/web/read, which returns any of them as clean markdown.

Cross-store pricing for a single game — Steam, Epic, GOG and Microsoft Store side by side — with the lowest price ever observed, the date it was observed, and how far above that low the current price sits. Storefronts publish today's price and no history, so the low exists only for whoever recorded it; ours runs from 2012. Every response resolves the game's family so a base game is never compared against a season pass.

The same as paid-ping, plus how long verification and settlement actually took, measured server-side. For choosing your own client timeouts from evidence rather than guessing. Settlement on Base typically completes in one to three seconds, so a timeout under five seconds produces false failures on a healthy network.
