Why this exists

Built for hostile input

A Turkish address arrives as "Cd." or "Cad." or "Caddesi", with the flat number glued to the building number. Generic parsers drop half of it silently. This one tells you what it could not place.

Every number carries its provenance

Each archived point stores the source URL and a content hash of the page it came from, and the archive is committed to a Merkle root anchored in Bitcoin. Every commitment — with its cutoff, leaf count and anchors — is published at /proof, so you can check for yourself how current the latest one is. The bulletins themselves are public and anyone can read them; what this adds is that a number you quote can be shown to be the number we held on that date, and that it has not been edited since.

You only pay for work

Repeated inputs come from cache and cost zero credits. If a response ever fails its own schema, the call is refunded automatically.

/v1/tr/labor Turkish Severance, Notice & Leave deterministic 1 credit

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.

Parameters

startDate* string Employment start date (YYYY-MM-DD).
endDate* string Termination date (YYYY-MM-DD). Inclusive of this day.
monthlyGross* number Gross monthly wage the severance is based on (giydirilmiş brüt).
asOf string Rate table date. Defaults to endDate.
age integer Employee age at termination — affects annual-leave entitlement (under 18 or 50+).
unusedLeaveDays number Unused annual-leave days, if you also want the unused-leave gross.

/v1/tr/vat Turkish VAT & Withholding deterministic 1 credit

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.

Parameters

amount* number The amount to tax. See amountIncludesVat.
amountIncludesVat boolean If true, `amount` is the gross (KDV dahil); if false, it is the net/matrah. default false
rate number | number | number | number VAT rate in percent. 0, 1, 10 or 20. default 20
withholding string Withholding fraction such as "5/10", or a code from the list (reklam, tasima, hurda, isgucu…).

Credits are consumed per call and cache hits are free. Requests without a key run on a narrow per-IP demo quota so you can evaluate before signing up.

The API key is e-mailed the moment payment clears. Upgrades keep the same key, so your integration is never broken.

Use it from an AI assistantthe same catalogue, exposed as MCP tools

Every endpoint is also published over the Model Context Protocol, so Claude, ChatGPT or your own agent can call it directly — no glue code, no wrapper functions. The assistant sees the same input schemas and the same metering.

Currently 25 tools. New endpoints appear automatically; nothing to update on your side.

  const first = apis[0];
  return first.slug.split(/[/-]/).map((p, i) => (i === 0 ? p : p[0].toUpperCase() + p.slice(1))).join('');
})()}(${esc(JSON.stringify(apis[0].examples[0]?.input ?? {}))});
console.log(r, r.$meta);
