## Tools (as reported by the server, not verified)

- `new\_launches`: Freshest DEX pools on Solana or Base \(newest first\) with age in minutes, liquidity, 5m/1h volume, buys vs sells and instant red flags \(no liquidity, sells far below buys, extreme FDV/liquidity\). Filter by minimum liquidity and maximum age. Pipe results into token-sell-check before buying. \($0.005 US
- `tx\_explain`: Paste any Solana signature or Base tx hash and get a one-sentence English explanation \(e.g. 'Wallet X swapped 0.5 SOL for 1,203,442 BONK on Jupiter'\), the action type \(swap, transfer, mint, failed...\), net asset changes for the signer and fee. Chain auto-detected. \($0.005 USDC per call via x402 at h
- `wallet\_portfolio`: One call returns a USD-valued portfolio across Solana and Base: SOL, every SPL/Token-2022 holding, Base ETH and USDC, each priced from live DEX liquidity, sorted by value, with dust and unpriced tokens flagged. Pass solana, evm, or both. \($0.005 USDC per call via x402 at https://coinlight-app.vercel
- `token\_sell\_check`: Pre-trade safety in one keyless call, chain auto-detected. Solana: quotes a real buy-then-sell round trip through Jupiter routing \(sell route exists? round-trip loss %, price impact\) plus Token-2022 traps \(transfer fee, transfer hook, permanent delegate, non-transferable, default-frozen\) and mint/fr
- `uuid`: Generate 1-50 random v4 UUIDs from a cryptographic RNG, e.g. for idempotency keys. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/uuid\)
- `text\_stats`: Count characters, words, lines, bytes and estimate LLM tokens for a text, so an agent can budget context before sending it. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/text-stats\)
- `time\_convert`: Convert a unix timestamp \(seconds or ms\) or ISO date into ISO UTC, unix seconds, unix ms and a relative 'x ago' string. Omit input for the current time. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/time-convert\)

- `hash`: Hash a string with sha256, sha512, sha1 or keccak256 and get hex and base64 output. Handy for commitments, idempotency keys and checks. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/hash\)
- `units\_convert`: Exact, bigint-safe conversion between human and atomic units: SOL\<-\>lamports, ETH\<-\>gwei\<-\>wei, USDC\<-\>atomic \(6 decimals\) or any decimals. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/units-convert\)
- `address\_validate`: Tell what kind of address a string is \(Solana base58 or EVM 0x\), whether it is valid, and its EIP-55 checksum form. Catch typos before sending funds. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/address-validate\)
- `base\_transaction`: Look up a Base transaction hash: success or failure, block, from, to, value, gas used and fee paid. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/base-transaction\)
- `base\_gas`: Current Base gas price and latest block, in wei and gwei, plus the cost of a plain ETH transfer and an ERC-20 transfer. \($0.005 USDC per call via x402 at https://coinlight-app.vercel.app/p/base-gas\)
