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

• GET/exa-contents$0.002Exa's own page index, read per call — no Exa account, no subscription. Pass urls= (one, or up to 5 comma-separated) and get each page as clean text with title, author and publish date. Answers from Exa's crawl rather than our fetcher, so it reads pages a plain server-side GET is blocked from. maxChars=500..40000 (default 8000). One URL is $0.002; a batch of 2-5 is $0.008, which the 402 challenge quotes. Pairs with exa-search: search, then read the winners.
• GET/deployer-rep$0.04Profiles the token's creator wallet: how much history it has, how much of the supply the creator still holds, and whether ownership is renounced — rolled into a 0-100 reputation score with signals. A fresh wallet holding 20% of supply with no renounce is the classic rug setup; this is the forensics layer other checks skip.
• GET/b20-mint-watch$0.03🆕 b20-supply shows the dilution ceiling; this shows the actual printing. Every mint (incl. batchMint) in the window: amount, recipients, and the share of current supply it represents — heavy_dilution / active_minting / minor_minting / quiet. The live issuance feed for agents holding B20 stablecoins and RWAs. Pass days= (1-90, default 30).
• GET/dns-lookup$0.002Resolve DNS records for a domain via Cloudflare DNS-over-HTTPS — A, AAAA, MX, TXT, NS, CNAME, SOA. Pass name= and type= (default A). Returns each record with its TTL, plus NXDOMAIN when the name does not exist. The DNS commodity agents call constantly for infra, email and domain checks, served at the sub-cent floor. Not financial advice.
• GET/sepa-creditor$0.002Validate a SEPA Creditor Identifier offline: country, check digits (mod-97), business code and national id. Catches mistyped creditor ids before a mandate setup. Structure only — not a scheme-manager registration proof.
• GET/base-withdrawal$0.04🆕 Beryl (2026-06-25) cut the single-proof withdrawal window from 7 days to 5, with a dual-proof fast path at ~1 day. Given a Base withdrawal-initiation tx, this decodes the L2ToL1MessagePasser event (the withdrawalHash, target & value needed to prove/finalize on L1) and estimates the finalization windows under the post-Beryl rules. For agents managing cross-chain liquidity.
• GET/file-convert$0.005Convert between the shapes data actually arrives in: CSV or TSV to JSON, JSON to CSV or TSV, CSV to a Markdown table, Markdown to HTML. Proper RFC 4180 parsing — quoted fields, embedded commas and newlines, doubled quotes — so a spreadsheet exported by a human does not silently come apart. Numbers and booleans get real types (turn it off with typed=false). No model call and no upstream: local parsing only.
• GET/base-block$0.002🆕 One block on Base — height, hash, parent, timestamp and age in seconds, transaction count, gas used against the limit, and the base fee in gwei. Takes a block number, a 0x… block hash, or latest / finalized / safe / earliest. A block that isn't mined yet answers found:false with the reason rather than an error. Raw chain data, no interpretation.
• GET/fund-trace$0.1first-funder goes one hop; this walks the funding chain back up to 8 hops to a recognisable origin (a CEX/bridge on-ramp — lower-risk provenance) OR a SANCTIONED address (dirty money, taint by provenance) OR a dead-end of fresh anon EOAs (the sybil/burner-cluster shape). One verdict compliance can refuse on. Best-effort: internal-transfer funding is invisible and ends the walk, never guessed. A CEX origin is a signal, not identity. Not financial advice.
• GET/exit-liquidity$0.02Give a Base token + a trade size in USD → estimated buy AND sell price impact, whether you can unwind that size without collapsing the pool, and the largest safe exit. The hidden form of a rug isn't 'you can't buy' — it's 'you can't sell'. Built for trading agents sizing positions.
• GET/email-verify$0.02Syntax + live DNS (MX/A) + disposable, role and consumer-mailbox detection, as one GO / HOLD / STOP verdict with the reasons listed. Catches throwaway inboxes, support@-style shared mailboxes and one-character domain typos (gmial.com). No SMTP probe, so mailbox existence is not claimed.
• GET/wallet-nfts$0.02Lists the NFT collections a Base wallet holds — name, count and floor value — spam-filtered, via Covalent. For agents profiling a wallet's NFT exposure.
• GET/nft-floor$0.02Current floor price for a Base NFT collection (OpenSea / LooksRare) via Alchemy. Pass the collection contract address. Coverage is limited to marketplace-listed collections. For agents tracking NFT markets.
• GET/price-impact$0.03A quote shows today's price; it does NOT tell you a $5k buy into a $20k pool pays ~20% more. This takes the token's deepest Base pool, treats it as constant-product (Uniswap-V2 / Aerodrome volatile) and computes the exact x*y=k price impact for your USD size. Conservative — concentrated-liquidity pools usually do better. Also returns the largest size under 1% and 3% impact. Pass address= and size= (USD). An estimate; confirm with swap-route. Not financial advice.
• GET/address-label$0.005What is this Base address? Matches a sourced registry of known protocol, exchange, bridge, locker and burn addresses (each with the docs/deployments/Basescan source it came from), then reads the chain: contract vs EOA (EIP-7702 delegation shown), ERC-4626 vault (asset()), Safe multisig (getThreshold), DEX pool interface (token0/token1). Unmatched addresses are reported as unlabelled, never guessed.
• GET/basename-profile$0.02🆕 Resolves the complete Base identity behind an address or Basename: resolved address, avatar, description, website and social handles (X/Twitter, GitHub, Farcaster, Discord) read from Base's L2 Resolver text records. Lets an agent turn a counterparty address into a real profile — beyond just the name. Complements address-trust (verification) with the human context.
• GET/b20-authenticity$0.02🆕 Run FIRST on any 'B20'. A scammer can deploy a normal contract at a vanity 0xB200… address and fake the whole B20 read surface — the B20Factory precompile is the one authority that can't be spoofed. Verifies factory registration + bytecode absence (real B20s are chain-native precompiles with no code). verdict: genuine / fake_lookalike / not_b20. The 2-cent check that keeps every other B20 answer honest.
• GET/ai-extract-batch$0.1The pipeline version of ai-extract: send up to 10 documents (text1=…&text2=… or texts= with ||| separators) and one field list — get one schema-enforced JSON object per document, in order, from a single paid call. 10 extractions for $0.10 instead of 10x the per-call overhead: built for agents parsing feeds, inboxes, scrape batches and receipt piles. Up to 6K chars per document.
• GET/token-age$0.01When was this token born — its earliest transfer on Base — and how old is it in days, with a verdict: brand_new (<1d), very_new (<7d, where most rugs happen), new (<30d), established, or mature. New is not bad, but age is a first-order risk input every agent should have before sizing. Pairs with launch-snipers and token-risk. Not a safety verdict on its own. Not financial advice.
• GET/base-nonce$0.002🆕 The next nonce for any Base address, plus its ETH balance and whether it is a contract. The count means different things either side of that line — transactions sent for a wallet, contracts deployed for a contract — so both are reported under their own name instead of one ambiguous number. What you need before building a transaction, or to tell a fresh address from a used one.
