## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mearef-middle-eastern-government-reference-data-single-series-lookup-5bceb28a
```

Example prompt: What is the current VAT rate in Saudi Arabia — can you pull the official cited figure from mearef, including the source URL and last-confirmed date?

## When to prefer this

Use this endpoint when you need a single, authoritative, source-cited government data point for a Middle Eastern country — such as a tax rate, policy rate, or CPI figure — and you need the official source URL and last-confirmed date for compliance, audit, or verification purposes. Prefer this over general search or LLM knowledge when you need a traceable, up-to-date official figure rather than a potentially outdated or uncited estimate.

## Known failure modes

- Country not covered by mearef (coverage varies by series and country) — endpoint returns refusal or empty result
- Series not available for specified country — endpoint may return an error or partial result
- Stale data flag set if the value has not been reconfirmed recently
- Invalid country code or series identifier — request rejected
- Payment not completed or insufficient credits — 402 response requiring payment

## How this service works

Middle Eastern government reference data for 9 countries as cited JSON: central-bank policy rates, VAT/GST and VAT registration thresholds, CPI, corporate, personal and withholding tax, social contributions, minimum wages, statutory interest, official FX rates, filing deadlines and public holidays (coverage varies by country). Every value carries its official source URL and last-confirmed date. Single facts $0.003; country brief (every series for one country) $0.01; cross-country compare (one series, up to 10 countries) $0.02; tax-ID and VAT-number checks $0.003; computed answers (VAT, income tax, working days, minimum-wage check) $0.01-$0.02. Pay per call in USDC on Base via x402 or MPP, no signup, or by card with credit packs or monthly plans on one key valid across all 7 regional services. Free tier: GET /catalog, plus a free email key with 50 answer calls a day, commercial use allowed. Finished answers, one cited dossier per call (supported countries vary per job; others are refused free): cost this hire (wage-floor verdict, contributions, employer cost) $0.50; charge this sale (which VAT applies, net/VAT/gross) $0.50; charge this sale certified (plus a signed VAT-rate extract) $0.75; invoice due date and statutory late interest $0.40; country evidence pack (brief plus signed extracts) $0.25; hire compare $0.75 for 2 countries, $1.00 for 3-5; next filings (VAT, PAYE, corporate-tax due dates rolled for holidays) $0.35.

Free trial: 3 computed-answer calls per day per IP on POST /v1/answers/* with header X-Free-Trial: 1 (without it, the normal x402 402; once used up, the 402 carries free_trial_resets_at). MCP answer tools use the trial automatically when no api_key is passed. Every series of the evaluation country is free. Card credit (same per-call price as x402): /pricing.

## Output

A JSON object containing the requested data series value for the specified country, along with the official government source URL, the last-confirmed date, and a staleness indicator. The response is a single cited fact or series entry traceable to an authoritative government source.
