title: 1gateway Company API
version: 0.1.1
description: '1gateway lets AI agents buy the data and APIs they need, one call at a time: no signup, no API key, paid per request with USDC on Base or Solana via x402. Coverage: company and compliance checks (sanctions, KYB, SEC filings, Korean companies), Korean real estate, trade and macro data, onchain and market data, and agent utilities such as document-to-Markdown. Every response names its source. Failed calls are never charged.'
x-guidance: 'Use this API when an agent needs data as English JSON with pay-per-call access and no signup. Common tasks: Korea apartment sale transactions and district price summaries, Korean public holidays, Korea company KYB (company resolve, profile, NTS business status, DART filings, supplier check), Korean HWP/HWPX to Markdown, web page to Markdown (web read), and document extract (PDF, DOCX, HWP/HWPX or web page to structured JSON). Current coverage is South Korea: apartment sale prices (MOLIT), exports/imports and 10-day export flash (Korea Customs), Bank of Korea statistics (ECOS), weather forecast by lat/lon (KMA), holidays (KASI); more APIs and countries are coming. Base onchain reads: token risk, wallet balances, token info, transaction status. Also: document → Markdown conversion for web pages, PDF, DOCX and Korean HWP/HWPX (price by detected type, decided before payment). Every /v1 endpoint is paid: call it, receive HTTP 402 with PAYMENT-REQUIRED, pay with an x402 client (USDC on Base or Solana, same price) and retry. No charge on failure: settlement happens only on 2xx; 4xx/5xx are never charged. Agent guide: https://1gateway.dev/agents.md. Status: https://1gateway.dev/status. MCP (Streamable HTTP) is available at https://1gateway.dev/mcp: initialize and tools/list are free, tools/call is paid via x402 _meta.'

x-billing-policy: 'No charge on failure: payment is settled only after the endpoint returns a 2xx response. Any 4xx or 5xx (bad input, no data, upstream error, timeout, disabled endpoint) is not settled, so the signed payment is never collected. Input is validated before the 402 wherever possible. Over MCP, a tool result with isError is not settled either.'
