CitedTravel gives AI agents and developers travel facts they can cite. It covers plug types and voltage, currency, emergency numbers, driving side, public holidays (3 years) and tipping norms for 195 countries, plus a visa/entry pilot for GB, US and JP passport holders. Every value comes with its sources (publisher, URL, license, verbatim quote), a last-verified date and a 0-1 confidence score with reasons. Data comes only from sources that allow commercial reuse, such as Wikidata, Unicode CLDR, UK FCDO, the US State Department and Japan MOFA. Entry answers quote official government pages and are decision support, never a go/no-go verdict. Remote MCP server (Streamable HTTP, 9 read-only tools) and REST API (OpenAPI 3.1). Answers in English, Japanese, Simplified and Traditional Chinese. Free: static facts need no key; a free key adds 1,000 calls/month. Paid: Builder $19/month, Pro $99/month, or x402 pay-per-call in USDC on Base.

64 individually priced Chinese company data tools at 0.011 USDC per call via remote MCP/x402 on Base; 68 MCP definitions total. Legacy Basic (3 modules, 0.032 USDC) and Full (9 modules, 0.093 USDC) remain separate packages. Additional HTTP x402 products, NOT new MCP tools: Standard screening 0.29 USDC (ten Jinghai checks, JSON plus Chinese/English HTML); Enhanced screening 0.59 USDC (the same ten checks plus exactly one QCC qualifications check); QCC qualifications 0.03 USDC (normalized JSON, up to 30 records, no screening analysis). Product guide: https://yangchunhong3000.github.io/cn-evidence-public-docs/products.html Discovery is free; data queries require a funded Base USDC wallet and explicit x402 spending approval. Plain MCP clients do not pay automatically. Most V3 company tools require company_id from company_detail; record details use record_id from a matching, separately paid parent list. New paged lists return at most five first-page rows; legacy lists at most ten. No automatic pagination, top-up, retry or repayment. Provider balance and service availability apply. Selected records and limited-scope screening only: empty is not no risk; statistics/trends are not detailed records. No complete due diligence, human review, factory verification or supplier-safety guarantee. Native MPP is paused. Internal owner-funded HTTP company-detail, Standard and old QCC v1 samples passed paid delivery/recovery checks. The later QCC v2 funding-policy revision has offline/isolated and unsigned checks, not a fresh funded acceptance. These tests are not customer sales or certification of every tool or MCP client.
