Blockchain And Crypto x402 offerings

Prepaid credit of $0.10 for paid API calls without signing each request. On CommsHarbor it pays for business e-mail for your domain from about $1.62 for 30 days (3 mailboxes), priced in Brazilian rea…

Compare crypto assets and stocks side by side (e.g. symbols=ETHUSD,BTCUSD,NVDA) on momentum, buy pressure, activity, anomaly and signal, sorted by momentum. Use to choose between several assets.

Mining revenue per algorithm (WhatToMine) — USD/day on a reference GPU rig.

Large-move candidates (up or down). Optional theme:robinhood for Robinhood Chain meme rotation via Pump.fun SOL routing.

Solana wallet token snapshot (Helius when configured) or EVM address ack

Screened yield pools (Jupiter, Meteora, DLMM, major DEX/lending venues)

Unlock one creator RWA signal (full intelligence summary)

Meteora DLMM pool deep-dive — TVL, APY, bin step, volume, and IL risk flags (Solana moat)

Top-trader long/short positioning proxy (Binance futures)

Potential airdrop candidates — insider Lounge signals first, then institutional/onchain/narrative overlay

Potential exchange listing candidates — insider-first multi-source alpha desk

EVM address checksum and validation — check an Ethereum/Base address format before sending funds.

Base58 encode or decode bytes/hex (Solana-style base58).

Agent Commerce Gate — bind a settlement receipt to a prior decision — per call

x402 Inspector scan (payment-challenge validation) — per call

Fetch a verified contract's ABI and metadata by address, keylessly, from Sourcify. Returns the ABI plus a summarized list of function and event signatures, the contract name and compiler, and proxy detection (is_proxy + implementation address). Block explorers gate the ABI behind an API key; this does not. Chains: base, ethereum, arbitrum, optimism, polygon, bsc, avalanche. No API keys, no LLM, one x402 USDC micropayment per call.

Admin activity monitor for contract owners and security teams: flags ownership transfers, implementation upgrades, and pause-state changes in a contract's recent history. Category: data.

Is this address a contract, and what code does it hold? Returns isContract, deployed bytecode size, and the keccak-256 hash of the bytecode (stable fingerprint for comparing deployments) on Ethereum, Base, Polygon, Arbitrum, or Optimism. Keyless multi-endpoint failover.

Returns the creator address and creation details for an Ethereum contract.

Fetch contract event logs (eth_getLogs) on Ethereum, Base, Polygon, Arbitrum, or Optimism - bounded so it always answers: block range capped at 2000 blocks (default: the last 100, auto-narrowed for busy contracts), at most 200 logs returned (truncated flag set if more matched). Filter by contract address and optional topic0 (event signature hash). Keyless multi-endpoint failover.

Use when an agent is about to send funds and must decide whether the destination is a plain wallet or a contract: returns isContract and the size of the deployed bytecode. A wallet where you expected a contract, or the reverse, is the cheapest mistake to catch before signing. Do not use to judge whether a token is safe (/v1/evm/token-safety) or worth trusting (/v1/evm/verdict). No API key, no account.

Reads who controls a contract straight from chain: owner/getOwner/admin, pending owner, EIP-1967 proxy implementation + admin, and paused state — and whether the owner is a single EOA key (one compromise = total control) or a contract (multisig/timelock). Crucially: ownership 'renounced' is NOT safe if it is still an upgradeable proxy whose admin can swap the logic. The control-surface read before you trust a contract. Not financial advice.
