Base URLhttps://402.com.tr/api/x402

• GET/ai-contract-risk$0.04Combines security flags with the verified ABI's function names, then AI explains the contract's dangerous capabilities — owner can mint, pause, blacklist, upgrade or self-destruct — with a danger level. Goes beyond raw flags to read what the contract can actually do.
• GET/near-staking-yields$0.02Measured APY of NEAR liquid staking (LiNEAR, Meta Pool stNEAR): each token's redemption price in NEAR now against N days ago from an archival node, annualised — no advertised rates. Plus NEAR staked behind each, and the cost of exiting instantly by selling for wNEAR through NEAR Intents instead of waiting ~2–3 days to unstake. days sets the window (default 7), size the exit in USD.
• GET/stablecoin-mcap$0.01Total stablecoin market capitalisation and the largest stablecoins by circulating supply across all chains (DefiLlama), with peg type/mechanism and live price — plus a depeg watch flagging any USD-pegged coin 2%+ off a dollar. The stablecoin-market commodity agents track; for a single Base-stablecoin peg check use stablecoin-peg. Not financial advice.
• GET/watchlist-diff$0.06Retention in one call: pass up to 10 tokens to snapshot them and get a watchId; call again with that watchId to get only the DELTAS since last time — liquidity ±%, price ±%, became-honeypot, sell-tax spiked, liquidity pulled. The second call is worth more than the first. Built for agents holding positions that re-check daily.
• GET/b20-policy-admin$0.04🆕 b20-control reads the token's own roles; the address that can actually add you to a blocklist lives in the Policy Registry. This reads WHO administers each active transfer/mint policy (policyAdmin), and whether that control is being handed over (pendingPolicyAdmin) or renounced. The other half of 'who can freeze/seize you', straight from the registry.
• GET/b20-supply$0.04🆕 The dilution half of B20 rug risk (b20-safety covers seizure). Reads supply cap vs minted supply (how much can still be minted) plus the on-chain SupplyCapUpdated history — an issuer that RAISED the cap diluted, or set up to dilute, holders. Uncapped mint is flagged as the worst case. Pair with b20-control to see who holds the mint role.
• GET/sanctions-name$0.05Sanctions screening for NAMES, not wallets. Pass a person or company; get GO / HOLD / STOP against the official U.S. Treasury OFAC SDN export, including a.k.a. aliases. Conservative by design: only a full-name match is a hit. Screening aid, not a compliance determination.
• GET/activity-trend$0.03Not price momentum — ADOPTION. token-age tells you when a token was born; holder-distribution is a snapshot. Neither shows the TRAJECTORY. A token can pass every static check and still bleed users week over week — what a human sees watching for days, an agent can't. Reads weekly transfer counts and distinct participants over the last 28 days and calls it: accelerating, steady, cooling, dying, or low_activity. Activity ≠ price; pair with wash-trading. Not financial advice.
• GET/agent-reputation$0.03The payer-trust mirror of x402-seller-check. Reads a wallet's outgoing USDC payments on Base over 90 days: distinct sellers paid (breadth), total payments and USDC (depth), and whether it ever paid the same payee twice. Breadth with no depth in a short burst is the crawler/sampler pattern; a repeat or sustained payer is the opposite. Sees only Base USDC; absence reads as 'thin', never bad. Not financial advice.
• GET/compliance-check$0.03Combined counterparty screening for an address: direct OFAC sanctions match, EOA/contract profile, and (for contracts) risk flags — rolled into a single recommendation (blocked / review / clear). Built for compliance agents.
• GET/position-health$0.04The post-trade check everything else skips: given a token, your position size and (optionally) entry price, returns live price & P&L, whether the position can still be EXITED at that size, and the token's current rug score — combined into a healthy / watch / exit_now verdict with reasons. The risk that changes after you buy is exactly the risk holders miss.
• GET/address-intel$0.02EOA vs contract, ETH + USDC balance, transaction count and activity level — straight from Base RPC. Useful for counterparty and wallet checks.
• GET/volume-check$0.02Reads the deepest pool's 24h volume, buy/sell counts, liquidity and price move, and scores how organic the activity looks. Volume 10x+ the pool's liquidity, near-perfect buy/sell symmetry, or big volume that moves the price nowhere are the classic wash-trading signatures used to bait buyers. Returns a 0-100 suspicion score and verdict.
• GET/b20-freeze-check$0.03Checks whether a specific wallet is authorized under a B20 token's transfer-sender policy. If it isn't, that wallet can't transfer and can be burnBlocked() (SEIZED) by the issuer. The personal companion to b20-safety — 'can this token freeze MY funds?'
• GET/b20-seizure-history$0.05🆕 Every other B20 check reads what the issuer CAN do; this reads what they HAVE done. Scans the token's actual burnBlocked seizures (the BurnedBlocked event) — whether the issuer has ever burned a blocked holder's balance, who was seized, and how much. verdict: enforced (has seized) / armed (can, hasn't) / no_seize_power. Pass wallet= for one address, or omit address= for the network-wide feed.
• GET/proxy-check$0.03Reads the EIP-1967 proxy slots live: is the contract upgradeable, what's the current implementation, and WHO can upgrade it. Flags the dangerous case — an EOA admin that can swap the logic at any block with no timelock/multisig. Upgradeability is a rug vector static scans miss.
• GET/paymaster-check$0.05🆕 Given a paymaster address, audits whether it's a healthy, active gas sponsor. Reads its UserOperationEvents across both EntryPoints: sponsored op volume, distinct accounts served, success rate, total gas sponsored, and concentration (the share coming from its single busiest app). The read to run before integrating a paymaster (Coinbase / Pimlico / Alchemy / custom), or judging who funds a counterparty's gas. paymaster= required, days= optional (default 30, max 90). Not financial advice.
• GET/secure-token$0.01Generate N cryptographically-strong, url-safe random tokens server-side — session IDs, API nonces, one-time codes, coupon secrets. Pass count= for how many. A tiny paid utility for agents that need entropy without a crypto library.
• GET/tax-id-check$0.002Offline tax/customs id formats: EORI, US EIN/SSN, UK NINO, AU ABN (checksum), TR VKN/TCKN (checksum), CA BN. kind= selects the scheme. A well-formed id is not proof of registration.
• GET/multi-price$0.02Pass a comma-separated list of up to 10 Base token addresses and get USD price + 24h change for each in one call. Ideal for agents pricing a portfolio or watchlist.
• GET/domain-check$0.02Registration age, expiry and registry status for any domain, from RDAP — the registries' own protocol. Returns days since registration, days to expiry, registrar, EPP status codes, nameservers and DNSSEC as one GO / HOLD / STOP verdict. Domain age is the strongest cheap signal in invoice and vendor-impersonation fraud: the payment details that change always arrive from a domain registered weeks ago. Refuses rather than guessing when a registry publishes no RDAP.
• GET/b20-batch$0.08Runs the B20 safety verdict across up to 5 B20 tokens in one call — each scored for freeze/seize/pause/rebase/uncapped-mint, with the worst score surfaced. For portfolio holders and agents screening several B20s at once.
• GET/morpho-health$0.04🆕 First lending tooling in the catalog. Reads a Morpho Blue position on Base (the largest lending venue on Base) and returns its liquidation health in one call: health factor, current vs liquidation LTV, and the exact collateral price drop that triggers liquidation. Built for borrowing agents and treasuries that need to know how close they are before the market cuts them — Morpho's own API is deferred. Pass wallet= and optionally market= (defaults to cbBTC/USDC). Not financial advice.
• GET/file-publish$0.01Send Markdown (or HTML) and get back a URL that renders as a real page — headings, tables, code blocks, mobile-readable, no scripts and no external requests. The other half of an agent's output problem: file-slot is for bytes it will fetch back, this is for the report somebody has to read. Retention 1-30 days. Published on the storage origin, never on 402.com.tr.
• GET/near-lending-health$0.02Health factor of an account's Rhea Lending (Burrow) position on NEAR, computed as the contract does — collateral discounted and debt marked up by each asset's volatility ratio — with collateral and debt in USD, how far collateral can fall before liquidation, and GO / HOLD / STOP. Positions from the contract, prices from NEAR Intents.
