Blockchain And Crypto x402 offerings

Crowd Check instant verdict for trading bots ($0.01): ok, caution or avoid for a token, with risk score, top reasons and key flags (liquidity pullable, serial launcher, v4 hook, bundled share). Tokens our hunt already checked answer instantly; others return 202 with no charge until ready. Base, Ethereum, Robinhood Chain, Solana. ?chain=&token=

Who is behind a wallet: age, activity, who first funded it, its ENS/Basename and the X account linked on it, every token it deployed and how many we proved were honeypots or scams (from 130k graded Base tokens), rug-ring funders and address-poisoning attempts. Returns stable signal ids plus a trust verdict. Not charged when the wallet has no history.

One-call launch screening for launchpads and trading apps: pass a token, get a GREEN / CAUTION / BLOCK decision (action: allow / review / reject) with plain-English reasons. Combines a live honeypot/tax simulation and owner-power analysis with the checks no other scanner has — whether the DEPLOYER or the exact CODE has rugged before (from a 35k-verdict ledger). Drop it into your listing flow to auto-reject rugs before they ever go live. Cache-first, so a repeat token is near-instant and free.

Focused honeypot check: a live buy-then-sell simulation against real DEX liquidity (Aerodrome, Uniswap V2/V3/V4). Tells an agent whether the token can actually be SOLD, the round-trip loss percent, and whether GoPlus or honeypot.is flag it too. Catches sell-blocking scam tokens, extreme sell taxes and no-liquidity traps before a buy is placed.

Crowd Check full scan ($1): is the crowd real? Profiles the top 300 real holders of a token on Base, Ethereum, Robinhood Chain or Solana - wallet age, real funder traced through routers, funder clusters, fresh wallets, snipers, launch bundles, dev and insider holdings, risk score 0-100, verdict organic/mixed/farmed. Free quote first at /v1/holders/quote, then ?quote=<id>; returns a job, call again with the same quote for the result.

Full safety report for an ERC-20 token. Runs a live buy-then-sell honeypot and tax simulation against real DEX liquidity (Aerodrome, Uniswap V2/V3/V4), scans contract powers (upgradeable proxy, mint, pause, blacklist, fee-setting), resolves ownership and effective controllers, and cross-checks GoPlus and honeypot.is. Returns an A-F grade, tradeable flag, 0-100 risk score and evidence-carrying flags an agent can cite.

Watch a token for 24 hours ($0.10). Returns a ticket. Poll it later for alerts: liquidity down 30 percent, price down 50 percent, top holder up 10 points, creator balance down 50 percent. Plain language, one sentence each. Pay once, then poll as often as you like at a few cents a poll.

Paper test ($0.05): what would have happened if you had followed a rule on every new token we found? Pick a preset (avoid_farms, locked_pools_only, clean_checks, small_pools_only, farms_only, everything) or set your own filters, a horizon of 1, 6 or 24 hours and a bankroll. Returns trades, win rate with interval, average and median return, drawdown, crash rate, and the same numbers for ALL tokens as a baseline, with fees and price impact charged.

Crowd Check quick check ($0.02): instant risk score 0-100 with reasons for a token on Base, Ethereum, Robinhood Chain or Solana - snipers, launch bundles (wallets fed in one launch tx), dev holding and whether the dev sold, dev-fed insiders, padded holder count, top-10 share, whether the creator can pull the pool (liquidity lock), risky trading hooks, creator rug record. Get a free quote at /v1/holders/quote, then ?quote=<id>.

Crowd Check creator check ($0.01): who is behind a token - its creator wallet, the funding chain behind it (up to 8 hops), the track record of earlier tokens, wallet age and throwaway-wallet signals, and any registered name and X account linked to the creator (claimed or proven both ways). Serial launchers flagged. Base, Ethereum, Robinhood Chain. Free quote first at /v1/holders/quote, then ?quote=<id>.

Token contract risk check for any EVM token, run by us directly on chain: rug-pull red flags such as unverified source, code that can be swapped later (upgradeable contract) and who controls that, ownership not renounced, and dangerous powers in the bytecode (mint, pause, blacklist, fee-setting). Returns the raw on-chain evidence, not just a score, so an agent can justify its decision.

Crowd Check pool safety ($0.01): can the token's liquidity be pulled - who holds the pool share (burned, wallet, or a lock service with the real locked share and unlock date) and, for Uniswap v4, what the pool's hook may do on every trade and whether it is a launch platform's shared hook. Free quote first at /v1/holders/quote, then ?quote=<id>.

DeFi TVL for protocols and chains. Returns total value locked per DeFi protocol or per chain via DefiLlama, with category, supported chains, and TVL change over time, filterable by category or chain. For DeFi protocol screening, chain-level TVL comparison, and tracking where liquidity is moving. Keyless.

DeFi data from DefiLlama in four modes. protocol: TVL, 1d/7d change, category, market cap and chain breakdown of a protocol (slug or name, e.g. aave, uniswap, lido). top: largest protocols by TVL, optional category (e.g. Lending, Dexs, Liquid Staking) and chain filter. chains: chains ranked by TVL with share. dex_volume: 24h/7d/30d DEX volume and top DEXes, optionally for one chain.

Total DeFi TVL for every chain DefiLlama tracks, ranked. Query: limit (1-500). Each: name, tvl_usd, token.

Blockchains ranked by DeFi total value locked with each chain's share of the total, native token, EVM chain id and CoinGecko id. Use it when an agent is comparing chains by DeFi activity or needs the canonical ids to query other services about a chain.

Solana DeFi total value locked overview from DefiLlama. Use when an agent assesses macro DeFi health and capital allocation on the Solana ecosystem.

Credit-analyst primitive for agents: compares live top stablecoin DeFi yields (DefiLlama) against the official US Treasury Bill rate (US Treasury Fiscal Data) in one call. Returns the risk-free rate, top on-chain yields, the spread for each, and a verdict on whether on-chain yield currently compensates above risk-free. TradFi + DeFi combined — no other single endpoint does this.

DeFi yield and APY across pools. Returns the top yield-farming pools via DefiLlama with current APY, base and reward APY split, TVL, chain, and project, filterable by chain, project, symbol, stablecoin-only, minimum TVL, and minimum APY. For yield discovery and comparing APY across protocols. Keyless.

Find DeFi yield pools across 400+ protocols and 100+ chains (DefiLlama data): APY split into base and reward, 30-day mean APY, 7-day APY change, TVL, stablecoin flag, impermanent-loss risk. Filter by chain (e.g. 'Base', 'Ethereum'), project (e.g. 'aave'), token symbol (e.g. 'USDC'), stablecoin_only, min_tvl_usd (default 1,000,000); sort by 'apy' (default) or 'tvl'. Outliers (flagged by DefiLlama or above 500% APY) are excluded unless include_outliers is true.

Top DeFi yield-farming pools by APY across ~15,800 tracked pools, live from DeFiLlama: TVL, base/reward APY split, 7d APY change, impermanent-loss risk, and exposure type, with a $1M TVL floor to filter out illiquid noise. Optionally filter to one chain or stablecoin-only pools. Not ticker-specific. Supports optional limit (default 10, max 25). $0.01/call.

Daily APY and TVL history for one yield pool, up to ten years, with a summary of latest, minimum, maximum and mean APY and the TVL change over the window. Use it when an agent is judging whether a pool's current yield is typical or an outlier before allocating to it.

Every DefiLlama yield pool, filtered and sorted server-side so you don't fetch the 11MB index. Query: chain, project, symbol, min_tvl (USD), min_apy (%), stablecoin (true/false), sort (tvl|apy), limit (1-100). Each pool: project, chain, symbol, tvl_usd, apy, apy_base, apy_reward, stablecoin, il_risk, exposure. APYs move — poll it.

Live yield opportunities across DeFi, filterable by chain, protocol, token symbol, stablecoin-only, minimum TVL and minimum APY: pool identity, TVL in dollars, total APY split into base and reward, 1-day, 7-day and 30-day APY change, impermanent-loss risk and exposure type. Use it to find, compare or monitor where a given asset earns the most right now.
