true402 Address Safety
Structural safety profile for ANY Base address — an EOA or an arbitrary contract — before an agent sends funds to it, approves it, or calls it. Returns contract-vs-EOA, ETH + USDC balance, tx-count (activity), and for contracts: whether it is a recognised ERC-20, ownership state, a mint() selector, and crucially whether it is an EIP-1967 upgradeable proxy (its logic can be swapped after you trust it). Coarse risk band + flags. On-chain reads only — no API key. POST {address}. First few checks free, no wallet (free trial).

true402 Backlinks
A domain's backlink profile: referring domains and pages, the dofollow split that actually carries authority, authority rank, spam score, broken backlinks and link composition by TLD, type, attribute and country. POST {target}.
POST /v1/backlinks · $0.10 / request
true402 DeFi Yields
DeFi yield aggregator — filter + rank live lending/staking pool APYs across every protocol/chain (DefiLlama, ~15k pools). POST {chain?, project?, asset?, stablecoinOnly?, minTvlUsd?, includeOutliers?, limit?} → pools sorted by APY (percent units) with apyBase/apyReward split, TVL, stablecoin + ilRisk flags, and the DefiLlama poolId for follow-up. Exploit-y outlier pools excluded by default. Keyless public data. Pay per call with x402. First few calls free, no wallet (free trial).

true402 Deployer Reputation
Who created this Base token, and how established is that wallet? Resolves the token's deployer and profiles it: wallet age (tx-count), balance, how many contracts it has shipped, and whether it is a FRESH throwaway spun up for the launch (a common rug setup) — the discriminating caution. Reputation context a structural or honeypot check can't see: an established deployer is reassuring, a brand-new one is a flag. Raw contract count is reported as context, NOT a rug verdict (legit protocols ship many). POST {token}.

true402 Deployer Reputation (Ethereum)
Who created this Ethereum token, and how established is that wallet? Resolves the token's deployer and profiles it: wallet age (tx-count), balance, how many contracts it has shipped, and whether it is a FRESH throwaway spun up for the launch (a common rug setup).

true402 Token Dossier
Everything we know about a Base ERC-20, in one call — the full Token Report (ERC-20 conformance, ownership, mint-capability, liquidity depth, buy/sell honeypot simulation, live rug + whale activity, avoid|caution|ok verdict) PLUS two things the cheaper report cannot carry: the deployer's reputation (wallet age, what it shipped before) and the durable liquidity archive for this token (every pool, every removal with amount/block/tx, and the other tokens drained in the SAME transaction — operator linkage). Those two are what separate a bad token from a serial rugger. Every section reports its own status and the response names what could NOT be established, because a silently missing section reads as reassurance. POST {token}. On-chain reads — no API key.

POST /v1/link-preview · $0.003 / request
true402 Liquidity History
Observed liquidity history for any Base token, from our own DEX archive. POST {token, limit?} to get every pool we have indexed for it, every liquidity-removal event with the amount removed, block and transaction hash, and the other tokens drained in the SAME transaction (one actor, several pools). Unlike a live honeypot simulation, this answers what ALREADY happened — a pool drained last month simulates fine today if it was re-seeded. Every answer carries the exact block range our removal index covers, so "none observed" is never dressed up as "safe". On-chain log indexing — no API key. First few calls free, no wallet (free trial).
POST /v1/base/liquidity-history · $0.005 / request
true402 Liquidity Pulls
Liquidity-pull / rug alerts on Base — Burn (liquidity-removal) events on recently-launched DEX pools (Uniswap V3 + Aerodrome). POST {since?, limit?, dex?, minQuote?}; each event gives the pool, token, and WETH/USDC amount removed (the rug magnitude). An early rug warning — cross-check the token with /v1/token-safety. On-chain log indexing — no API key. First few calls free, no wallet (free trial).

true402 New Pairs
Recently-created Base DEX pairs (Uniswap V3 + Aerodrome) — fresh token launches for trading agents/snipers.

On-chain log indexing — no API key. First few calls free, no wallet (free trial).

true402 Token Report
Flagship "can I safely ape in?" composite for a Base ERC-20 — one call instead of five. Runs the full token-safety check (ERC-20 conformance, ownership, mint-capability, WETH/USDC liquidity depth, and a buy/sell honeypot simulation), enriches it with the live recent liquidity-removal (rug) + whale-swap activity on the token, and returns a single avoid|caution|ok verdict with reasons. POST {token}. Cheaper than buying token-safety + liquidity-pulls + whale-swaps separately. On-chain reads — no API key. First few checks free, no wallet (free trial).

true402 Token Safety
Rug/honeypot safety check for an ERC-20 token on Base: ERC-20 conformance, ownership renounce, mint-capability, WETH/USDC liquidity depth (Uniswap V3 + Aerodrome), and a buy/sell honeypot simulation (gas-free eth_call round-trip — catches buy-but-can-not-sell traps). 0–100 score + risk flags.

Rug/honeypot safety check for an ERC-20 token on BNB Smart Chain (BSC): ERC-20 conformance, ownership renounce, mint-capability, WBNB/USDC liquidity depth (pancakeswap-v3 + pancakeswap-v2), and a buy/sell honeypot simulation (gas-free eth_call round-trip — catches buy-but-can-not-sell traps, including tokens that whitelist their operator so the trade counters look healthy). 0–100 score + risk flags.

true402 Token Safety (Solana)
Rug/trap safety check for a Solana SPL or Token-2022 token: mint authority (supply inflation), freeze authority (the Solana honeypot — the issuer can freeze your account so you cannot sell), Token-2022 extensions (permanent delegate = your tokens can be moved out of your wallet, transfer hook = issuer code can block your transfer, transfer fee) and pool liquidity depth across Raydium/Orca/Meteora. 0–100 score + risk flags. POST {token} with a base58 mint. NOT a buy/sell simulation — Solana has no EVM bytecode, so the eth_call round-trip the Base/Ethereum/BSC stalls run does not exist here. On-chain reads — no API key. First few checks free, no wallet (free trial).
POST /v1/solana/token-safety · $0.005 / request
true402 Transaction Preflight
Check a Base transaction BEFORE signing it. POST an UNSIGNED tx {from, to, data?, value?} and get three independent lenses: a simulation against current state (does it revert?), the decoded intent (is this an unlimited approval that outlives the trade?), and the counterparty's liquidity-removal history from our own archive. Takes NO private key and NO signature, so the service cannot broadcast or front-run the transaction it inspects — that is the design, not a limitation. Never returns "safe": a clean result means these checks found nothing, and every response says so. First few calls free, no wallet (free trial).

true402 Whale Swaps
Whale swaps on Base — recent large ($-value) DEX Swap events (Uniswap V3 + Aerodrome) on tracked pools, for whale-following / copy-trading agents. POST {min?, dex?, since?, limit?, direction?}; each swap gives the pool, token, quote (WETH/USDC), USD size, direction (buy/sell of the token), block + approx age. On-chain log indexing — no API key. First few calls free, no wallet (free trial).
