Execute one bounded eth_call against Base, Ethereum, or Arbitrum and return raw deterministic call data without signing or broadcasting.
Facts about an ERC-20 contract read from the chain (Ethereum, Base, Arbitrum, Optimism, Polygon): name, symbol, decimals, total supply, USD price and fully diluted value. Use to verify a token address before trading or i...
X402 Asset Match: compares a challenge asset identifier with buyer-supported assets using only bounded caller-supplied values. Call when you need a bounded x402 asset match result before paying for or accepting an x402 o...
Agent Result Citation Check: checks bounded citation objects for URL and title fields using only bounded caller-supplied values. Call when you need a bounded agent result citation check result before paying for or accept...
Agent Result Error Shape Check: checks an agent error object for code, message, and retryability using only bounded caller-supplied values. Call when you need a bounded agent result error shape check result before paying...
X402 Delivery Content Type Check: compares delivery content type with buyer-accepted media types using only bounded caller-supplied values. Call when you need a bounded x402 delivery content type check result before payi...
X402 Settlement Network Check: compares settlement chain with the accepted challenge network using only bounded caller-supplied values. Call when you need a bounded x402 settlement network check result before paying for...
Determine whether an address on Base is a contract or an externally owned account. POST {"address":"0x..."} and receive isContract, the bytecode size in bytes and its keccak-256 hash. Useful before sending funds to an un...
JSON Schema validation without external libraries: validates data against a schema supporting type, required, properties, additionalProperties, items, enum, const, min/max (length, items, properties, numeric, exclusive),...
Fetch the verified ABI for a contract address from Sourcify, plus a ready-to-use list of human-readable function signatures with their 4-byte selectors. Covers 8 EVM mainnets. Unverified contracts return a structured {ve...
Decentralised exchange volumes: totals, 24h/7d/30d windows, per-chain and per-protocol breakdowns, all in one payload cached at the edge. For market-structure work and volume share screens.
Is this address a contract? On Ethereum, Base, Arc or BNB Chain: whether code is deployed, its size, the implementation behind an EIP-1967 or ZeppelinOS proxy, and an EIP-7702 delegation if the address is a wallet that d...
Contract-code check for a Base mainnet address (is_contract + code size + EIP-7702 delegated-EOA detection).
Raw storage slot (eth_getStorageAt) of a Base contract. Use when an agent needs proxy implementation/admin slots or raw contract state.
Fetch a verified smart-contract's full source, ABI, compiler settings and NatSpec docs for an EVM address, and automatically resolve a proxy to its implementation so the response also carries the implementation ABI. One...
Get the full detail of one US federal award by its generated_internal_id (returned from /govcon/awards): award id, type, description, total obligation, dates, awarding agency hierarchy and recipient with parent. The dril...
Fetch just the ABI of a verified EVM contract, resolving a proxy to its implementation ABI as well. A cheap slice for when you only need the interface to encode calls or decode data, not the full source. Unverified contr...
