Temsor API — Turkey & EU business data

Checks an e-mail address: syntax, whether the domain can actually receive mail, disposable and role-account detection, and typo correction. No SMTP probing. Most competitors connect to the target server and try RCPT TO, which sounds thorough but produces a confident-looking number you cannot trust:

Validates an EU VAT number against the official VIES register, with per-country format checks and honest handling of upstream outages. VIES is free but unreliable: member-state services drop out individually and a failed lookup can easily be mistaken for a rejection. Treating an outage as "invalid"

Validates an IBAN from any of 70+ countries: checksum, country length and in-country account structure, and resolves the bank and branch codes. Most free libraries stop at the mod-97 checksum. That only says the digits are self-consistent — not that the number could exist in that country. This chec

Searchable, dated archive of what every public MCP server actually exposes — tool definitions, daily change feed, and rug-pull detection. The official MCP registry publishes a server’s name and address but not its tool surface; the only way to learn what a server exposes is to connect and call `too

Dated archive of LLM prices, context windows, announced retirement dates and quiet delistings across 400+ models and 50+ providers. Providers overwrite their pricing pages and drop models from their catalogs without publishing what changed. This endpoint keeps a daily record, so three otherwise una

Independent daily record of what changed behind a provider endpoint: which alias resolved to which model, and when behaviour shifted. Providers update models behind stable endpoint names. This endpoint publishes an independent measurement: a fixed probe suite is sent daily at temperature 0, three r

Validates and normalises a phone number to E.164, classifies the line type, and resolves the province for Turkish landlines. For signup and checkout flows that need to store one canonical form and reject typos early. Turkish numbers are handled in depth: landline area codes resolve to a province, m

Screens a name against six official sanctions lists — US OFAC, UN, EU, UK OFSI, Switzerland SECO and Canada — with transliteration-aware fuzzy matching. Six official lists are reduced to one schema, so a name is checked everywhere at once instead of six integrations. Cyrillic and Arabic names are t

Returns the accumulated history of public data series with change statistics and a source receipt for every point. Currently ingesting the Turkish Central Bank daily FX bulletin (`tcmb.usd`, `tcmb.eur`, …), normalised to one unit so JPY-style 100-unit quotes stop biting. Leave `seriesId` empty to l

Identifies which carrier a tracking number belongs to, validates it where a checksum exists, and returns the canonical tracking link. Built for order systems that receive numbers from many carriers and have to route the customer to the right tracking page. Turkish carriers mostly use plain numeric

Splits a free-form Turkish address into neighbourhood, street, building, floor, flat, district, province and postcode. Handles the abbreviation chaos (Mah./Mh., Cd./Cad., Sk./Sok., No:12/5, K:3 D:7), cross-checks the province against the postcode, repairs misspelled district names against a diction

Adds business days or counts them between two dates, accounting for Turkish public and religious holidays including half-day eves. Ramadan and Sacrifice feasts follow the Hijri calendar and cannot be derived reliably by formula, so announced dates are read from a table; years without an official an

Petrol, diesel and heating-oil pump prices for all 81 Turkish provinces, including the price in force on any past date. The distributor publishes today's pump price and a per-district history query, one district and one range at a time. This endpoint answers the question that actually costs money,

Builds a UBL-TR e-Invoice or e-Archive XML document from plain JSON, computing every total and validating the parties. Selling into Türkiye means issuing a UBL-TR document whose element order is fixed by schema and whose totals must agree to the kuruş, or the integrator rejects it. This endpoint ta

Turns a UBL-TR e-Invoice or e-Archive XML document into clean JSON: parties, line items, taxes and totals. Works regardless of the namespace prefix the sender used (cbc:, cac:, ns0:), normalises single-line documents into arrays, and reports amount mismatches in `warnings` instead of returning quie

Writes a monetary amount out in Turkish words, the way invoices, cheques and promissory notes require. Applies the rules that trip up generic libraries: Turkish says "bin", never "bir bin"; the kuruş part is read separately; and both "1.234,56" and "1,234.56" are accepted and told apart automatical

Validates Turkish national ID, tax number, IBAN, licence plate, IMEI and barcodes from one endpoint, with type auto-detection. Goes past a yes/no: resolves the bank behind an IBAN, the province behind a licence plate and the GS1 country prefix behind a barcode. Pure local computation — no upstream
