Count exact LLM tokens for a string using the real OpenAI BPE (o200k_base for gpt-4o/o-series, cl100k_base for gpt-4/gpt-3.5). Deterministic, offline - budget context windows without calling a model.
Transcribe audio to text using OpenAI (gpt-transcribe)
Transcribe audio to text using OpenAI (gpt-transcribe). Provide a URL to an audio file (mp3, wav, m4a, etc.) and get back the transcript. No API key needed; pay per call via x402. Max 4 minutes of audio, 25 MB file size; /api/transcribe-pro takes the same model to 10 minutes.

Read one known URL: the main article content as clean markdown with title, byline, excerpt and word count, boilerplate removed. Use it when an agent already has a URL and needs the text; for JavaScript-rendered pages that return an empty shell, use a browser render instead.

Fetch the verified Solidity source files and compiler metadata for a contract address from Sourcify's open verification repository. Covers 8 EVM mainnets (ethereum, base, polygon, arbitrum, optimism, bsc, gnosis, celo). Contracts that were never verified return a structured {verified:false} miss, not an error. Feed the returned source into /api/solidity-scan for a heuristic pattern check.

Read-only JSON-RPC against Ethereum, Base, Polygon, Arbitrum, or Optim
Read-only JSON-RPC against Ethereum, Base, Polygon, Arbitrum, or Optimism with built-in multi-endpoint failover - one paid call, no node or API key of your own. Prefer the named reads (block-number, chain-info, block-info, event-logs, erc721-owner, contract-code) for common tasks - they validate inputs and cost less; use this when you need a whitelisted method they do not wrap.

Decode EVM smart-contract transaction calldata into the function name
Decode EVM smart-contract transaction calldata into the function name and typed parameters. Supply an ABI (from /api/contract-abi) or a signature like transfer(address,uint256) for a fully offline decode; with neither, the 4-byte selector is resolved via the openchain.xyz signature database (4byte.directory fallback) and each candidate signature is tried. Unknown selectors return a documented partial decode (selector + raw 32-byte words) instead of an error.
