description: 'An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol''s published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.'
x-guidance: 'Market data over 25897 listed x402 services, 30-day window. For protocols beyond x402 (Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry)) use /economy, /economy/protocols and /economy/search. For x402, start with GET /search?q=<capability> for ranked services, or /top for the highest-demand ones with callsPerPayer (near 1 means each payer bought once, high means repeat use). /price benchmarks what comparable services charge, /networks breaks demand down by chain, /tags is the capability vocabulary, /count is the market totals, /service looks one service up by URL, /report and /alpha are the category report and the underserved niches, /dataset is the full export. Premium: /dataset/pro ($25) is the enriched full export (demand rank overall and within the top tag, per-seller and per-category aggregates) and /report/weekly ($5) the market report; /dataset/teaser is a free 5% sample in the /dataset/pro row schema. EVERY paid route answers a call with no parameters at all with real data rather than an error, so a blind purchase is never wasted. If you transferred the price to payTo in USDC, USDT or DAI on Base without a payment header, just call the route again within 30 minutes and it serves the data (one transfer, one response); other transfers are never matched automatically: claim them with ?tx=<hash> (on /pay/check use ?payment_tx=<hash> instead, since its tx is the transaction being checked) on Base, Ethereum, Arbitrum or Polygon (USDC, USDT, DAI, WETH, cbBTC, WBTC, USDT0 where that chain has the token, or native ETH/POL), ?btc=<txid> (BTC), ?sol=<signature> (SOL, USDC, USDT), ?tron=<txid> (TRX, USDT TRC-20) or ?stx=<txid> (STX, sBTC); a direct transfer on any other chain, or of a token not named here, cannot be claimed. The two premium routes are the exception and serve a plain transfer only when it is claimed with ?tx=<hash>. /sample, /health and /dataset/teaser are free. Payment is x402 v2, scheme exact, networks eip155:8453, eip155:42161, eip155:137 (USDC); stacks:1 (sBTC); eip155:43114, eip155:10, eip155:42220 (USDC via UltravioletaDAO); eip155:42161 (USDT0), eip155:1 (USDC) via UltravioletaDAO, or MPP (method evm, intent charge, USDC on EVM networks, same prices); a plain transfer on Base, Ethereum, Arbitrum or Polygon also works via ?tx=<hash>.'

chain: base
chainId: 8453
risk: medium
reasons:
- no exact OFAC SDN match for the token, its owner or its proxy admin
- 'upgradeable proxy (OpenZeppelin (zeppelinos)): implementation 0x2ce6311ddae708829bc0784c967b7d77d19fd779 can be replaced'
rules:
- 'high: the token address, its owner() or its proxy admin is an exact match on the OFAC SDN list (Digital Currency Address entries).'
- 'medium: the token is an upgradeable proxy (EIP-1967 or OpenZeppelin implementation slot set: its code can be replaced), or it has a non-zero owner() and its bytecode (the implementation''s, for a proxy) contains a mint, pause or blacklist function selector.'
- 'unknown: the ERC-20 fields name, symbol, decimals and totalSupply could not all be read.'
- 'low: none of the above.'
- A selector in the bytecode means the function exists; who may call it is not checked. No contract code at the address, or no node answering, is refused before any charge.
grade: C
verdict: 'medium risk, grade C for this token: upgradeable proxy (OpenZeppelin (zeppelinos)): implementation 0x2ce6311ddae708829bc0784c967b7d77d19fd779 can be replaced.'

Screening against the OFAC SDN list as of 2026-10-02, not legal advice. Only the SDN list is checked (not OFAC''s non-SDN Consolidated lists or other countries'' lists).
