# Plainfold: full tool reference > Small, honest data tools for people and AI agents. Updated 2026-10-07. ## How to call these tools - Remote MCP server (streamable HTTP), all tools: https://mcp.apify.com/?tools=plainfold/sam-gov-contract-opportunities,plainfold/business-entity-check - One tool only: https://mcp.apify.com/?tools=plainfold/ - Auth: OAuth with an Apify account, or `Authorization: Bearer `. Runs are billed per event at the prices below. - Agents without an Apify account: Apify agentic payments (x402 USDC on Base, or Skyfire). - Plain HTTP: POST https://api.apify.com/v2/acts/plainfold~/run-sync-get-dataset-items with the JSON input as the body. - The MCP tool for each Actor also accepts `waitSecs` (how long the call waits for results). Longer runs return a run ID; fetch results with get-actor-run / get-dataset-items. ## SAM.gov Contract Opportunities Search and monitor U.S. federal contract opportunities from SAM.gov's official daily data extract: RFPs, solicitations, sources sought and award notices. - Returns federal contract opportunities as clean JSON, one row per notice, from SAM.gov's official nightly public extract (not scraped). - Filters by keyword, NAICS, PSC, set-aside (small business, 8(a), HUBZone, SDVOSB, WOSB), agency, state, posted date and deadline. - Keyword search is relevance-ranked and ignores the FAR/DFARS boilerplate that every defense notice repeats. - Can run on a schedule and return only notices that are new since the last run. Use it for: Finding federal contracts to bid on, daily bid alerts, market research by NAICS/PSC code, and award notices (who won what, for how much). Not for: State and local bids, non-U.S. tenders, attachment downloads, or historical spending data (use USAspending.gov). Price: $0.002 per opportunity returned + $0.002 per run (about $0.20 per 100 results). No SAM.gov API key needed.

Use it for: Vendor and supplier checks before paying, KYB onboarding, lead qualification, and confirming that a company named in a contract, invoice or email actually exists. Not for: People lookups, states other than NY/CO/OR/CT/TX, credit or financial data, or a legal certificate of good standing. Price: $0.004 per company found, $0.0005 per lookup with no match, + $0.0005 per run. Failed lookups are not charged.
