Every agent-payable API.

Use when an agent must tell a user what a transaction did. Input: tx (Base hash or Solana signature), network=eip155:8453|solana (optional, inferred). Output: explanation (1-3 sentences; every number checked against the decoded facts, template fallback), facts: status, time, fee, from/to, called function (curated selector table), ERC-20 transfers, approvals, inferred swap (sent/received), Solana programs. Example: ?tx=0x…&network=eip155:8453

Transaction lookup on Base, Ethereum or Solana: give a transaction hash or signature, get its status, sender, fee and every token transfer.

Transaction lookup: status and decoded details for any tx hash or Solana signature, read onchain. EVM (auto-detects Ethereum, Base, Arbitrum, Polygon): success/reverted, block time, from/to, method, fee in USD, every token transfer decoded; flags x402/EIP-3009 USDC payments. Solana: status, fee, SOL + token balance changes. 0.003 USDC (Base/Polygon/Arbitrum/Solana/Avalanche/Sei). Errors are never charged: 400 bad input, 422 nothing found or target unreachable, 503 busy.

Receipt of a mined EVM transaction: success or revert, gas used, effective gas price, fee (and L2 L1 fee), created contract and event logs with Transfer and Approval decoded. Use to confirm a payment or swap.

Live transaction receipt by hash via `eth_getTransactionReceipt`: success/failed status, block number, from/to, created contract address, gas used, cumulative gas, effective gas price (wei + gwei), tx type and the emitted event logs (capped). Complements `tx` (which reads the transaction itself). Returns `found:false` for unknown/pending hashes. Reads live on-chain data with automatic endpoint fallback.

Transaction receipt — did it succeed, what did it cost, what did it emit — Genesis402 / UnyKorn Operator Network

Transaction receipt by hash on Base mainnet: status, gas used, full logs, L1 fee breakdown, l1_fee_usd/total_fee_usd.

Transaction count (nonce) of a Base address.

Transaction details by hash on Base mainnet.

Receipt of a transaction: whether it succeeded or reverted, gas used, fee actually paid, and how many logs it emitted. The call that answers did my transaction work. Via eth_getTransactionReceipt.

Full receipt for a transaction hash in one call: status, block, from/to, value, gas used vs limit, effective gas price, total fee, tx type, calldata selector, contract created, plus every ERC-20 / ERC-721 / ERC-1155 Transfer event decoded locally from the logs (token, from, to, amount, tokenId) and the list of contracts that emitted logs. Receipt and transaction are fetched in a single batched request.

Dry-run a prospective smart-contract call or transaction without broadcasting it: executes eth_call and eth_estimateGas against the latest block over the same keyless multi-endpoint public RPC pool as /api/evm-rpc (ethereum, base, polygon, arbitrum, optimism). Returns the return data and a gas estimate on success, or {success:false} with the revert reason when the call would fail. Strictly read-only - nothing is signed or broadcast.

Influship YouTube video transcript with timestamped segments

Takes up to 20 transcript parts, each a list of segments with start, end and text, plus an optional speaker label and a time offset in seconds (where the part starts in the full recording). Offsets are applied, all segments are sorted by time, and the merged transcript is returned as a segment list, plain text with speaker labels, SRT and WebVTT. Overlapping segments from different speakers are kept and counted, which is normal for per-speaker tracks. Pure data processing; nothing is stored.

Uses the existing Deepgram and local media pipeline with one diarized transcription call. Subtitle cues split at speaker changes, pauses, six seconds or 84 characters. Unknown speakers remain null. Requires a lawful recording; submitted audio leaves this server for Deepgram, with the existing provider opt-out disclosure. Audio, transcript and subtitles are not retained. This synchronous request has no background job or callback.

Transcript+: audio/video URL or upload to a speaker-labelled (diarized) transcript, summary, chapters and SRT/VTT captions. Priced per audio minute.
