title: Ambolt data tools Tenders API
version: 0.1.1
description: Pay-per-call data endpoints using the x402 protocol (USDC on Base, Polygon and Solana). Failed calls are not charged.
x-guidance: 'Call GET /v1/<tool> with the documented query parameters. Without payment the response is 402 with the price and payment requirements; an x402 client pays in USDC and retries. Add free=1 for one free call per tool and IP per day. Company, tender, document, rates, on-chain and web tools; every response carries source and date. The same tools are available as MCP tools at /mcp (free, 30 requests a minute) and as Apify Actors. Company-level data only: no personal data.'
