How to get onto the X1 chain and fund a wallet with APEX/XNT from outside — bridge from Solana (USDC or SOL), or claim free tokens from the faucet. Returns the real bridge deposit address, limits and endpoints. Start here if you have no X1 balance.

SEVEN CHAINS, FROM LIVE RESERVES OR AN AGGREGATOR QUOTE (for an executed sell test use arc_exit_check on Arc or base_exit_check on Base). Before you buy a token, find out whether you can sell it. Give a token address and a position size in USD and this returns what you would actually receive, the slippage, and the largest position that exits under 5%. WORKS ON SEVEN CHAINS: Solana and X1 (base58 address, constant-product maths against the pool's live reserves and its own fee) and five EVM chains (0x address, routed through LI.FI to USDC) - Base 8453 (the default), Ethereum 1, Arbitrum 42161, Optimism 10, Polygon 137. Any other chain id returns UNSUPPORTED_CHAIN and names these five; it is never reported as a token you cannot sell. This is deliberately NOT a safety grade. Safety grades describe the contract (mint authority, LP burn, holder count); exitability describes the depth. A token can score 100 on every safety check and still be untradeable — PROOF does exactly that in our own data. Verdicts on Solana/X1: EXITABLE, PARTIAL, COSTLY, TRAPPED, THIN, NO_POOL, UNPRICED. On EVM: EXITABLE, PARTIAL, COSTLY, THIN, NO_ROUTE, UNKNOWN. NO_ROUTE means the aggregator we check found no way out, which is strong evidence and not proof that no venue anywhere will take it; UNPRICED and UNKNOWN mean we could not resolve a value and are NOT judgements about the token.

X1 Agent Passport: an ERC-8004 identity for your agent in the X1 Agent Registry (the Solana Agent Registry, deployed on X1 by APEX), done for you in one paid call. Returns the live price in XNT, where to pay, and the exact request. Pay the XNT to payTo from the wallet that should own the agent, then POST your {name, description, services?} to the route with the transfer signature in the X-PAYMENT header: we register the agent and hand its NFT to the paying wallet. Or register yourself for network fees only (see page).

The X1 Agent Registry in full: every registered agent, its owner and registration file, a live check of every endpoint it lists (MCP, A2A, x402 and the networks it accepts, web), whether it can be paid on X1, and feedback counts. The registry is new, so the list is short and says so. $0.003 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1). Call once without payment for the terms, sign them with your own wallet, call again with payment.

Did that X1 payment really land? Payer, how much reached the wallet you name in XNT or any SPL token (by balance change, so program-sent payments count), confirmed vs finalized, memos and fee, checked against what you expected. $0.003 per call over x402 (USDC on Arc, Base or Solana, or XNT on X1). Call once without payment for the terms, sign them with your own wallet, call again with payment.

Current XNT price in USD with its 24 h and 1 h change, read from the on-chain USDCx pool. For any other token use token_lookup.

Look up ONE X1 token by symbol or mint address: price in XNT and USD, holders, liquidity and 24 h volume in XNT, 24 h change. A symbol returns the best search match; when several tokens share a ticker, run impostor_check first and pass the mint. For a ranked list use top_tokens.

Ranked list of X1 tokens by liquidity in XNT, 3 to 25 entries (default 8): rank, symbol, name, liquidity, 24 h change. For one token's full numbers use token_lookup.

PAYWALLED. Portfolio exit analysis — pass up to 25 mints and get back which of your positions cannot be sold cleanly, ranked worst first. Answers "of everything I hold, what am I trapped in?" in one call. Returns x402 payment instructions for /api/x402/exit-check-bulk. For one token use exit_check; this one is for portfolios.

PAYWALLED. Is a token's volume real demand? Round-trip analysis of the last 24h: how much volume came from wallets buying and selling the same token back and forth (wash trading, arbitrage or market making) versus one-way trades, with the top round-trippers and pool liquidity. Returns x402 payment instructions for GET /api/x402/volume-check/{mint} ($0.004).

Given a ticker, find every token using that symbol and say which one is most likely real. 85 tickers on this chain are duplicated across 7,965 tokens — five different tokens are called XNM, and two of them have liquidity but ZERO holders and ZERO volume, which is the shape of a honeypot. Ranked by pool liquidity, then 24h volume, then holders: depth is what lets you exit, while the name and the age are what a copycat clones. Free. Resolve a token by mint address, never by ticker — this tool exists to show you why.

Every token balance of ONE X1 wallet, read live from the X1 chain: native XNT plus SPL and Token-2022 accounts, with symbols. If a read fails the answer says it is incomplete; it never reports an empty wallet it could not read. For trading history use wallet_profile.

Reputation and trading profile of ONE X1 wallet, from the trades our screener has indexed. For its current balances use holdings; for the leaderboard across wallets use top_traders.

The latest on-chain trades of ONE X1 token, newest first (mint or symbol, up to 100). For whale-sized swaps across every token use whale_ticker; for the last 200 trades chain-wide use firehose.

OHLC price candles for ONE X1 token (mint or symbol): timeframe 5m, 15m, 1h, 4h or 1d, up to 200 candles (default 80). For the current price alone use token_lookup.

Whale-sized swaps across ALL X1 tokens, newest first (up to 50). For every trade of one token use recent_trades.

Leaderboard of X1 wallets by NET XNT FLOW per token — NOT a profit and loss. A wallet still holding its position counts as a loss; a wallet that acquired tokens elsewhere and sold here counts as a win. No closed-position check is performed (audit 2026-09-17).

Flux Threat Intel — scam wallet and token findings on X1. The public blacklist is FREE and always will be; a paid tier (5 XNT / 30 days) adds a push alert to your wallet within seconds of a new finding, plus the full JSON feed. Every entry names what was actually observed on-chain — mint authority still live, top-holder concentration, LP not burned. Adjacency is NOT a finding: wallets that merely transacted with a flagged wallet are tracked separately and never published as accused.

Build an UNSIGNED swap transaction on X1 at the best price across XDEX and APEX AMM — direct, or two hops through XNT or APEX in ONE transaction, simulated against your wallet before it is returned. Returns base64 you sign with your own key and broadcast yourself; this server never holds your keys and never signs for you. Use mint addresses, or the string "native" for XNT. APEX mint is Du6Z596DwGnfUcMSyRHSBQzNybiQKu8GESVfruEv9Jqr. Check priceImpact before signing — thin pools move hard. Building is free. When you spend XNT (more than 0.01), the transaction includes a 0.1% platform fee to the APEX buyback wallet, shown as platformFee in the answer; otherwise you pay only the network fee.

How ERC-8004 works on Arc (and where the registry is on X1), from the spec and the deployed contracts: register an agent (and the one-call shortcuts), the registration file fields, proving your endpoint domain, pointing payments at an agentWallet, writing and reading reputation, and what explorers like 8004scan read.
