Questions about this API

What does 1gateway do?

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.

How much does 1gateway cost?

1gateway is priced at $0.0027 to $0.0045 USDC per request, paid per call with no subscription. The exact amount for each call is in the HTTP 402 response before any money moves.

Do I need an API key or account to use 1gateway?

No. 1gateway uses the x402 protocol, so an agent pays per request in USDC on Base and gets the response, with no API key, account or signup.

Has 1gateway been verified?

Not yet. 1gateway is listed and answers an x402 payment challenge, but PayAPI Market has not paid for a call to it, so it carries no settlement-verified badge.

How does an AI agent find 1gateway?

Through the free PayAPI Market MCP server at https://payapi.market/mcp, using search_apis or get_api, or over plain HTTP at https://payapi.market/agent/search. Discovery is free; the agent pays the provider directly on the listing's own 402.
