Returns declared license, SPDX normalization, and permissive-default compatible yes/no/unknown from the public npm registry. Triage only — not compliance-grade SBOM or legal advice. Workflow: call GET /license/check (or MCP check_npm_license) before npm install; if compatible=no, pick another package or escalate to human; if unknown, treat as risk. Example: left-pad@1.0.0 before install. Also: Convert amounts between ISO 4217 currencies using ECB daily reference rates (Frankfurter). Use for invoices, travel budgets, expense reports, and shopping comparisons when you need a verifiable rate instead of LLM arithmetic. Not live tradable FX — rates follow ECB business-day publication. Also: Resolve a place name or lat/lon to IANA timezone and coordinates (Open-Meteo). Use for agent scheduling, travel logistics, and local-time questions without LLM guessing. Not IP geolocation. Also: Translate short text between languages (Azure Translator). Use when an agent needs a verifiable string in another language for UI copy, messages, or research snippets — not legal, medical, or certified translation.","url":"https://payload402.edgebytenet.workers.dev/mcp","method":"POST","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","toolName","inputSchema"],"properties":{"type":{"type":"string","const":"mcp"},"toolName":{"type":"string"},"description":{"type":"string"},"inputSchema":{"type":"object"}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"to":"EUR","date":"2026-08-29","from":"USD","note":"ECB daily reference rates, not live quotes","rate":0.85825,"amount":10,"source":"frankfurter","converted":8.5825}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.001","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.001/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.001","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_dhILUDLsyZeQCbBqW7EhG","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.001","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Converts a monetary amount between two ISO 4217 currencies using ECB daily reference rates via the Frankfurter data source","exampleAgentPrompt":"Convert 250 USD to EUR using the ECB daily reference rate and give me the converted amount and the rate used.","exampleUseCases":[{"title":"Invoice amount in foreign currency","prompt":"I need to bill a client in Germany for $4,500 USD — convert that to euros using the ECB reference rate so I can put the correct amount on the invoice."},{"title":"Travel budget planning","prompt":"I'm heading to Japan and have a $3,000 travel budget — how much is that in Japanese yen based on today's ECB rate?"},{"title":"Expense report currency conversion","prompt":"I paid 180 GBP for a business dinner in London — convert that to USD using the ECB daily rate so I can file my expense report."}],"resultDescription":"Returns the converted amount, the exchange rate applied, the source and target currency codes, the date of the rate, and a note clarifying these are ECB daily reference rates (not live tradable quotes), along with the data source identifier.","failureModes":["Unsupported currency code returns an error — only ISO 4217 currencies covered by ECB are valid","Rates not available on weekends or ECB non-business days — most recent prior business day rate is used","Zero or negative amount input may produce unexpected results","Network or worker timeout returns a 5xx error","Payment failure (insufficient USDC balance) blocks the call before currency conversion occurs"],"whenToPreferThis":"Choose this endpoint when you need a verifiable, auditable ECB reference rate for invoicing, expense reporting, or travel budget calculations rather than a real-time tradable FX quote.
