Blockchain And Crypto x402 offerings

Execute one bounded read-only eth_call against a resolved Base mainnet block, retain call and block evidence, and optionally decode caller-specified ABI output types.

Read the latest Base mainnet block and a bounded EIP-1559 fee history in one RPC batch, including gas utilization and priority-fee percentile samples.

Read point-in-time ETH, native USDC, and up to four caller-selected ERC-20 balances plus account nonce and contract-code status at one resolved Base mainnet block.

Validate EIP-712 typed structured data and derive its domain separator, message hash, and signing digest.

Inspect Base mainnet contract bytecode, common token metadata, and ERC-165, ERC-721, and ERC-1155 interface signals at one resolved block.

Check one Base mainnet wallet or contract for ETH and official USDC balances, transaction nonce, and contract-bytecode evidence at a single resolved block.

Estimate gas for one Base mainnet transaction context at a resolved block, add a bounded caller-selected buffer, and preserve RPC rejection evidence without signing or broadcasting.

Get and inspect one historical Base mainnet block by exact number or a latest, safe, or finalized tag, returning its header timestamp, transaction count, gas use, base and blob fees, state and receipt roots, confirmations, and head-distance evidence.

Inspect Base transaction status and receipt evidence in one call, including success, revert, or pending state, confirmations, actual gas fee, recognized calldata, bounded ERC-20-shaped transfers, and official Base USDC recognition for payment confirmation.

Validate and normalize an Ethereum or EVM wallet address, distinguish valid, absent, or invalid ERC-55 checksum casing, and identify the zero address without a network request.

Token safety verdict: honeypot and rug-pull check with taxes, liquidity, admin powers and holders for a token address

Returns a current machine-readable PoCon operational snapshot of Agentic Swarm Marketplace activity: oracle prices, worker status, bazaar readiness, intake inventory, and signal flags. Intended for autonomous agents monitoring whether to purchase deeper marketplace intelligence. Optional fresh=1 rebuilds from live feeds.

Public Celo Sepolia soak/proof and x402 commerce JSON bundle settled in Base USDC. Use when an agent needs verifiable Celo-rail evidence packaged for buyers.

Replays a minted intake bundle by pack_id (same artifact files as the T54 rail), settled in Base USDC.

Constitution-first airdrop and incentive screening with Farm Score 0-100, risk flags, and optional EVM contract triage. No on-chain claim execution.

Normalized votes on a Snapshot proposal, ordered by voting power: voter address, resolved choice label, voting power, reason and timestamp. Tracks delegate participation and voting behaviour.

Profile of a DePIN hotspot or gateway from public data. Give network (helium) and an entity or asset key and get owner wallet, subnetworks (IOT, MOBILE), obfuscated location (city, state, country and H3 cell), elevation, gain, onboarding fee and computed flags for asserted location, multi-network and deployment completeness. Each value is cited to its source.
