## 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 sirenic-spanish-public-procurement-record-479ba8d6
```

Example prompt: Can you pull the public procurement record for Spanish company with NIF A28582013 — I want to see the contracts they've won and any notices they've issued as a buyer?

## When to prefer this

Use this endpoint when you need authoritative Spanish public procurement data keyed by a legal-entity NIF, including both contracts won and buyer notices from the official Plataforma de Contratación del Sector Público. Prefer this over generic web search when you need structured, machine-readable procurement records with EUR amounts, CPV codes, and buyer identifiers for due diligence, compliance auditing, or competitive intelligence on Spanish companies.

## Known failure modes

- Invalid NIF format (must be one letter + seven digits + check character) returns an error — DNI/NIE formats are refused
- No records found if the company has no procurement activity on the platform since 2012
- NIF belongs to a natural person — endpoint only serves legal entities
- Rate limiting or payment failure at $0.02 USDC per call
- Data may lag behind real-time as it depends on ministry CODICE feed update cadence

## How this service works

Public-procurement record of a Spanish company from the Plataforma de Contratación del Sector Público (Ministry of Finance CODICE feeds, hosted profiles and aggregated regional platforms, since 2012): contracts WON matched by legal-person NIF — buyer (name, DIR3), subject, CPV, lot, result, award date, amounts in EUR, tenders received, SME flag — and notices ISSUED as a buyer; newest first, capped at 100. Never a natural-person winner. Reuse under the ministry's conditions.

## Output

A list (up to 100 records, newest first) of public procurement contracts won by the company and notices issued as a buyer, each containing: buyer name and DIR3 code, contract subject, CPV codes, lot identifier, result status, award date, awarded amount in EUR, number of tenders received, and SME flag. Never includes natural-person winners.
