20 Services from api.jagent.dev

Returns real-time Base mainnet gas fee estimates with USD cost breakdowns for common transaction types, using live ETH price from Uniswap v3

Performs a live heuristic risk assessment of a token contract address on Base mainnet, returning risk level, token metadata, ownership, proxy status, and bytecode-level red flags.

Returns an AI-generated plain-English risk verdict (low_risk, caution, high_risk, or insufficient_data) for a given ERC-20 token contract on the Base blockchain, including a summary and key risk points.

Returns live wallet profile for a Base mainnet address, including account kind, nonce, ETH balance, and balances of 7 major tokens (USDC, USDbC, WETH, DAI, cbETH, cbBTC, AERO)

Returns an AI-generated plain-English profile of a Base blockchain address, including onchain data, a classification label, key points, and warnings.

Validates a 5-field cron expression and returns its next scheduled run times in UTC ISO format

Converts CSV text to JSON, returning an array of objects (with headers) or array of arrays (without), with optional type inference and delimiter configuration.

Pre-sign risk analysis of EIP-712 typed data messages, detecting dangerous approvals, transfers, and missing safeguards before signing

Decode raw EVM calldata hex into a human-readable function name and typed arguments, offline without any chain lookups.

Decodes raw EVM event logs (topics + data) into named, typed arguments offline, recognizing common token, NFT, and AMM events without chain lookups

Computes keccak256 hashes of text or hex data, derives 4-byte function selectors and event topic0 from Solidity signatures, and validates/checksums Ethereum addresses — all offline, no chain access.

Pre-sign offline risk assessment of EVM transaction calldata, flagging dangerous patterns like unlimited approvals, permit calls, and ownership changes

Computes cryptographic hash digests (or HMAC) of a string using one or more algorithms, returning hex and base64 encodings of the result.

Validates arbitrary JSON data against a JSON Schema definition and returns detailed validation errors with JSON-pointer paths

Converts an array of JSON objects into a RFC 4180-compliant CSV string, with options for column ordering, delimiter, flattening, and line endings.

Decodes and optionally cryptographically verifies a JWS-compact JWT, returning parsed header, payload, claims analysis, and signature validity.

Converts a Markdown string to HTML, returning rendered HTML, a headings outline, and input character count

Tests a JavaScript regular expression against input text, returning match details, groups, and optional string replacement results

Computes a line-based unified diff between two text strings, returning added/removed/unchanged line counts, hunk count, and a unified diff string.

Converts a time value between IANA timezones, optionally adding a duration offset and computing a diff to a reference time.
