Temsor API — Turkey & EU business data

Capability: mode=stub|ready from TEMSOR_RTP_*. No live RTP on forge; idle $0. GET /v1/pbx/whisper/status. Reports MediaBridge config presence (TEMSOR_RTP_PATH). mode=ready means path env set — not that Asterisk RTP is flowing. live_rtp/listening always false on forge (R2–R3 IVR sidecar; R4 lab E2E harness). No ≤400ms production claim. TEMSOR_RTP_LAB=1 → optional lab_latency_ms on suggest. No DID sales.

Live agent handoff cards (≤3): open promises/facts from in-call index. Idle $0. Lab: TEMSOR_RTP_LAB=1 → lab_latency_ms. POST /v1/pbx/whisper/suggest {call_id, partial_text}. Returns open promises and facts as whisper cards for agent handoff. Prefers in-call partial index when present. Mock latency_ms under 400ms (compat stub). Idle $0. No Telnyx/DID/live PSTN. Advanced: optional lab_latency_ms when TEMSOR_RTP_LAB=1 (measured; not prod SLA).

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, mobile and special ranges (toll-free 0800, fixed-rate 0850, premium 0900) are classified, and every accepted input comes back in both E.164 and national notation. One thing this endpoint deliberately does not claim: the current mobile operator. Turkey has had number portability since 2008, so a 0532 number may well be on another network today. Competing APIs report the prefix owner as "the operator" and customers pick SMS routes on that basis. We return it as `originallyAllocatedTo` with the caveat attached, because a confident wrong answer costs more than an honest gap.

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 transliterated, titles and corporate suffixes are stripped, and known spelling families are unified — "Abd al-Rahman", "Abdul Rahman" and "Abdulrahman" reach the same record. Every hit explains itself: which name matched, whether it was an alias the source flags as weak, and how the birth year and country compared. Supply `birthYear` whenever you have it; it removes most false positives. `asOf` screens against the lists as they stood on a past date, which is the question auditors actually ask — note that this is bounded by when our archive begins, reported in `coverage`.

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 list the catalogue. `fillGaps` carries the last value across weekends and holidays; `includeEvidence` attaches the source URL and content hash for every point, so a value can still be defended years later.

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 ranges that overlap, so a single confident answer is often impossible — this returns a ranked candidate list instead of inventing certainty, because sending a customer to the wrong carrier's page makes them think the parcel is lost. Universal Postal Union (S10) numbers are fully verified: the mod-11 check digit is computed, the service type and origin country are decoded. For formats whose checksum we have not verified against the standard, the result says `not-verified` rather than guessing — a wrong rejection is worse than an honest unknown. Delivery status is deliberately out of scope: Turkish carriers require merchant credentials for that, and scraping their sites would be fragile and against their terms.

Validates a tax identifier for 25+ countries: checksum where the algorithm is public, format-only where it is not. Country is required. Onboarding forms collect a tax number from whatever country the customer is in and then store garbage because they only checked the length. This applies the published checksum (SIREN/SIRET Luhn, ABN mod-89, CPF/CNPJ, NIP, BSN 11-proef, NIF/NIE, OIB, IČO, AFM, TCKN/VKN, …) and refuses to guess the country: the same 9 digits are a well-formed identifier in more than one place. Where the checksum is not published (US EIN, UK UTR, DE Steuernummer, IN PAN) the answer is format + `checksum: not-verified`, not a fake pass. This does not ask any tax authority whether the number is issued.

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 dictionary, and returns a confidence score. Anything it could not place is listed in `unparsed` — nothing is dropped silently. Built for shipping, checkout and CRM systems that receive Turkish addresses typed by humans.

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 announcement are returned with `confirmed:false` rather than guessed silently. For delivery promises, SLA clocks, payment terms and shipping estimates.

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, in a single call: what was diesel in Ankara on 12 March? Pass `asOf` for the price in force on that day — if the distributor did not change prices that day, the previous price is carried forward and `effectiveFrom` says when it started, with `carriedForward: true`. Pass `from`/`to` to get the change events in a window, each with the percentage move. Every figure carries the source URL and a content hash of the page it was read from, so the number can still be defended in an audit years later. Leave `province` empty to list coverage.

Builds a Turkish IBAN from a 5-digit bank code and account number, computing ISO 7064 check digits. A Turkish IBAN is TR + 2 check digits + 5-digit bank code + 1 reserved digit + 16-character account. This pads the account on the left, defaults the reserved digit to 0, computes the mod-97 check digits, and resolves the bank name from the same national table used by IBAN validation when the code is known. Unknown bank codes still produce a structurally valid IBAN with bankName null — existence at the bank is not claimed.

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 takes the invoice as ordinary JSON and returns the XML. Totals you send are ignored on purpose — line amounts, per-rate VAT subtotals and the payable amount are all recomputed here, because a rounding difference of one kuruş is the most common rejection. VKN and TCKN checksums are verified, and the amount is written out in Turkish words as invoices require. It does not sign the document and does not transmit it: the financial seal and the submission to the tax authority belong to your certificate and your integrator. What comes back is a document ready to enter that step.

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 quietly wrong totals. The job that costs accounting and expense software the most engineering time.

Computes Turkish severance (kıdem), notice (ihbar) and annual-leave entitlement from service dates and the gross wage, using the official ceiling and minimum-wage tables for the given day. Payroll and HR tools in Turkey chase a parameter that changes every January and July: the severance ceiling, the SGK cap, the minimum wage. This endpoint applies the statutory formulae (Labour Law 4857 arts. 17 and 53, former 1475 art. 14) to those tables. The ceiling is applied to the monthly wage, not the total. Stamp tax (0.759%) is deducted from severance; income tax is not — kıdem is exempt. Notice pay IS taxable; we return the gross and say so, because the actual withholding depends on the employee's cumulative tax base. What this will not tell you: whether the employee is entitled to severance at all. That depends on the reason for termination (retirement, just cause, marriage, military service…). Treating the number as "what is owed" is how you lose at trial.

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 automatically. A mandatory field on Turkish e-invoices, cheques and notes — with no off-the-shelf API until now.

Validates a 5-digit Turkish postal code and resolves the province from the first two digits (plate map). PTT postal codes are five digits; the leading pair matches the province plate code for the 81 provinces. This endpoint checks the shape, maps 01–81 to the province name, and returns null with confidence none when the prefix is outside that range — it does not invent a district. District-level resolution needs the full PTT directory and is out of scope here.

Builds a person-to-person TR Karekod (FAST) payment payload from IBAN, name and optional TRY amount. Text only — no PNG. Turkish instant payments (FAST) can start from a TR Karekod that encodes the payee IBAN and name in EMV-style TLV. This builds the person-to-person organisation (payload format indicator 750210): application template with IBAN, payee name, optional 12-digit kuruş amount, optional free-text explanation, and a CRC-16/CCITT-FALSE trailer. The Turkish IBAN is normalised and checked with ISO 7064 mod-97; non-TR IBANs and non-TRY currencies are rejected. This does not send money and does not render a QR image.

Computes the deemed-received date and the HMK deadline (with holiday shifting) for a Turkish notification, from the date the underlying event actually happened. Turkish notification law (7201) ties the deadline clock to an event that is not "the date on the letter" — for electronic notification the UETS platform reports send, read AND reached dates, and only the reached date starts the clock (art. 7/a: deemed received 5 calendar days after reaching the address, whether or not it was opened). HMK adds two more rules on top: the day of notification itself does not count (art. 92 — the period starts the next day) and if the computed last day lands on a weekend or a full public/religious holiday, it moves to the next business day (art. 93); a half-day eve (arife) does not shift it. What this will not tell you: whether the notification was itself valid, or what a specific `periodType` (itiraz, temyiz, cevap…) is in days for your case — that number differs by statute and we do not guess it; supply `periodDays` yourself. Only the "hmk" law family is covered so far.

Validates Turkish national ID, tax number, IBAN, licence plate, IMEI, barcodes, KEP, MERSİS, postal code and ISBN 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 service is called, so latency is microseconds and the answer never changes for the same input.

Splits a Turkish amount into net, VAT and (optionally) withholding: who pays the seller, who remits the withheld VAT. For invoice lines and checkout totals that have to show KDV dahil / hariç and, when the parties are in a withholding (tevkifat) situation, the split between what the buyer pays the seller and what the buyer remits to the tax office. Rates are 0, 1, 10 and 20 percent. Withholding is a fraction of the VAT (2/10 through 10/10), or a named code from the GİB partial-withholding list. The 2026 threshold (TRY 12,000 gross) is reported and compared with the amount, but `applies` is always null: whether withholding actually applies depends on the taxpayer status of both parties, which this endpoint does not know. Feeding it a fraction is not a legal opinion.

Validates UUID structure and reports version (1–5, 7) and RFC 4122 variant bits. Deterministic. Accepts dashed or 32-hex compact form. Reports the version nibble, variant (NCS / RFC 4122 / Microsoft / future), and whether the layout matches a known UUID version used in practice (v1–v5 and Unix-epoch v7). A valid structure is not proof the UUID was issued by a particular system.

Validates a 17-character VIN: forbidden letters, ISO 3779 check digit, WMI region/manufacturer, model year and plant. Typos in a VIN are usually a forbidden letter (I, O, Q — they look like 1 and 0) or a shifted character. This rejects those, splits WMI/VDS/VIS, and names the manufacturer when the WMI is in a conservative built-in table. The 9th-character check digit is computed and compared, but a mismatch does not fail the VIN: it is mandatory under FMVSS 115 in North America and routinely ignored in Europe. `checkDigitMatch` tells you; `valid` stays true if the 17-character form is legal. This does not decode the full vehicle (engine, body, options) and does not prove the VIN was issued.
