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

• GET/b20-transfer-preflight$0.04🆕 The per-transaction B20 rail check: pass token + from + to (+ optional executor) and get one GO/HOLD/STOP on whether this exact transfer clears NOW — sender policy resolved against the sender, receiver policy against the recipient, executor policy against the operator, plus live transfer-pause. Every other B20 tool is per-token due diligence bought once; this is the check an agent runs on every payment. No ERC-20 tool can see it.
• GET/counterparty-check$0.12One call, four public sources: how old the domain is (RDAP), whether mail to the contact will land (DNS), whether the name is on the OFAC list, and whether the company exists in the global LEI register. Returns a single GO / HOLD / STOP with every signal that produced it. Built for the moment an agent has to trust an invoice, a new vendor or a payment-detail change — the classic fraud pattern is a real-looking name on a domain registered weeks ago.
• GET/token-approvals$0.02Lists a wallet's active token approvals — which contracts can spend its tokens, the allowance, USD value at risk and a risk factor (revoke.cash-style). Essential wallet-security check for agents and users.
• GET/stock-position$0.04B20 Asset tokens do NOT apply multiplier() to balanceOf() — measured on chain: a multiplier moved 1.0→2.0 while holder balances read identically. Coinbase settles splits and dividend adjustments on its 13 tokenized equities through that multiplier, so reading balanceOf as a share count is wrong by exactly that factor the day one fires. Returns both numbers per holding: what an unadjusted integrator shows, and what is owed. Wallet balances only; LP/lending is declared excluded, never zeroed.
• GET/dex-spread$0.02A token on several Base DEXes should cost about the same on each; a gap is either an arbitrage window or, on a thin pool, a mispricing that signals wash/manipulation. Compares the price across the LIQUID venues (over a floor, default $5k): tight (trustworthy), arb_window, wide (likely mispricing), or single_venue (one pool, as manipulable as it is thin). Separates real arbitrage from thin-pool noise. Snapshots — confirm with a live quote. Not financial advice.
• GET/wallet-delegation$0.03🆕 Since Pectra an EOA can carry EIP-7702 delegated code (the 0xef0100 designator): every call to the wallet executes the DELEGATE's contract with the wallet's funds — a malicious delegate is total takeover, invisible to approval tools. Reads the designator, resolves the delegate and verdicts it: not_delegated / delegated_known (Coinbase's EOA→SmartWallet path) / delegated_unknown (🚨) / smart_contract. The drain surface no other Base tool checks.
• GET/holiday-calendar$0.002List public holidays for country= + year= from Nager.Date (~110 countries). Marks national vs regional entries. Same source business-days uses — for agents that need the raw calendar.
• GET/business-days$0.002Add business days to a date, or count them between two dates, for ~110 countries. Knows each country's weekend (Friday-Saturday where that applies, not just Sat-Sun) and its national public holidays, and names every day it skipped. Holidays observed only in some provinces are deliberately NOT treated as national closures — they are listed separately so you can apply them when your case is regional. Built for payment terms, SLAs and delivery dates.
• GET/ai-summarize$0.03Compress up to 16K characters of anything — articles, transcripts, email threads, reports — into 3-5 precise bullet points, one micro-payment per call. No API key, no subscription, no prompt engineering: send text=, get bullets back as clean JSON. The digest step for agent pipelines that read more than they can carry in context.
• GET/near-swap-status$0.002Status of a NEAR Intents swap by its deposit address: waiting for deposit, deposit seen, processing, done, refunded or failed — with amounts in and out, refund reason, and the origin and destination transactions. Use after near-swap.
• GET/breach-check$0.005Have I Been Pwned Pwned Passwords via k-anonymity: only a 5-char SHA-1 prefix leaves the server. Returns pwned + occurrence count and a GO/HOLD/STOP. Password is not stored. Email breach lookup not offered.
• GET/farcaster-social-velocity$0.03🆕 Measures real-time Farcaster / Warpcast social momentum for tokens, memecoins, and AI agents on Base. Quantifies hourly cast velocity, author diversity ratio, engagement quality, and detects sybil astroturfing vs genuine viral attention. Returns a 0-100 momentum score and ORGANIC_VIRAL vs ASTROTURFED verdict. Pass query= (ticker, e.g. 'HIGHER' or token name).
• GET/bridge-status$0.01The other half of bridge-route. A bridge takes minutes with funds in flight, and from the source chain alone an agent cannot tell if it completed. Tracks a transfer by its source tx hash via the LiFi status API: completed (with the receiving tx), pending (poll again), failed (with the reason), or not-found (not a bridge tx, or too early to index). Pass from/to/bridge for a faster lookup. not-found reads as 'not indexed yet', never 'failed'. Not financial advice.
• GET/ai-wallet-report$0.06The flagship wallet report: aggregates net worth, age/activity and recent transactions, then AI synthesizes a verdict (e.g. fresh/risky → established/active) with key observations. One call, agent-ready wallet intelligence.
• GET/multi-chain-gas$0.01Reads the live gas price on each major EVM chain an agent uses (base, arbitrum, optimism, ethereum, polygon) and turns it into the USD cost of the actions that matter — a plain transfer and a DEX swap — using live native-token prices. Returns one ranked answer with the cheapest chain, so an agent deciding where to settle doesn't make five RPC calls. A chain it could not read is 'unknown' and excluded from the pick, never guessed. Gas units are typical estimates. Not financial advice.
• GET/base-receipt$0.002🆕 The receipt for a Base transaction: success or reverted, block, gas used, effective gas price, the fee in wei and ETH, how many logs it emitted and which contracts emitted them. A contract deployment reports the new address. No receipt yet means pending, dropped, or never here — and it says which is possible instead of failing.
• GET/hs-code$0.005Map a short product description to likely HS chapter/heading hints (electronics, apparel, coffee, pharma, …). Keyword table only — not a binding customs classification; confirm before filing.
• GET/web-search$0.01Search the live web from an agent that has no browser: pass query= and get back ranked results (title, URL, snippet, relevance score) plus a synthesized one-paragraph answer over them. maxResults=1..20 (default 5); includeAnswer=false to skip the summary and take sources only. The step before reasoning about anything that happened after the model's training cutoff — prices, releases, incidents, docs. Nothing crypto about it.
• GET/b20-policy-watch$0.03The B20-only rug vector: a token can launch clean and later attach a sender blocklist (PolicyUpdated) — silently becoming seizable via burnBlocked. This reads the token's full policy/pause event timeline (CDP-indexed onchain events) plus the live policy state, and tells you if — and exactly WHEN — it turned seizable.
• GET/perp-funding$0.04Choosing between spot and a perp? This is the data that choice needs. Aggregate OI-weighted perpetual funding, open interest and basis for a coin across venues (CoinGecko, no key): who pays whom (longs crowded vs shorts crowded), the carry you earn or bleed holding the perp, and contango vs backwardation. Verdict neutral / elevated / extreme. Pass symbol=BTC. Funding annualised as an estimate (8h intervals assumed). A market-structure signal, not a price call. Not financial advice.
• GET/ping$0.002The cheapest possible end-to-end x402 purchase: always returns 200 with a timestamp (and echoes an optional message). Use it to verify your x402 client, the payment path and our settlement in one sub-cent call before wiring up a real endpoint — the pattern crawlers and monitors hit most across the network.
• GET/geocode$0.01Forward geocode an address (q=) or reverse geocode lat=+lon= using OpenStreetMap Nominatim. Returns up to 5 hits with display name and address parts. Community map data — not a postal authority.
• GET/b20-rebase$0.02Reads a B20 Asset token's rebase multiplier — the factor that scales every holder's balance. Flags whether balances are being scaled (invisible dilution/inflation the issuer controls). Stablecoin variants return no-rebase.
• GET/wallet-activity$0.03The latest transactions for a Base address — hash, time, from/to, ETH value, success — via Covalent. For agents tracking what a wallet is doing.
• GET/exa-search$0.01Exa's neural web search, resold per call — no Exa account, no subscription, one USDC micro-payment. Pass query= and get ranked results: title, URL, publish date, author, relevance score. numResults=1..10 (default 5). type=auto|fast|instant. includeDomains= restricts the search. Add text=1 for matched highlights from each page (caps results at 5, priced $0.03; the 402 challenge quotes it). For agents that need what the web says today, not what a training cutoff remembers.
