## 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 eu-tender-dealbook-search-api-x402-2b9ba534
```

Example prompt: Search EU tenders from the last 30 days for 'cybersecurity software' in Germany — I want to see what public procurement opportunities are out there for that niche.

## When to prefer this

Choose this endpoint when you need real-time EU public procurement data scoped to a specific B2B niche or keyword, especially when targeting sales leads from government RFPs or tenders. It is ideal for agents performing autonomous B2B lead generation or market scanning across EU procurement markets. Prefer it over general web search when you need structured, filterable tender data with country and value constraints. It is particularly useful for agents with x402 micropayment capabilities on Base, as it requires no subscription — just pay $1 USDC per call.

## Known failure modes

- Missing required 'q' keyword parameter returns a 400 or validation error
- Invalid country code may return empty results or an error
- days value outside 1–90 range may be rejected or clamped
- Payment failure via x402 (insufficient USDC balance or bad payment header) returns 402 Payment Required
- No matching tenders for the query returns count=0 with an empty results array
- Service unavailability on Railway deployment returns 5xx error

## How this service works

Pay-per-call B2B sales lead and procurement intelligence plus Base wallet data for agents. Search EU tenders/RFPs or inspect a Base wallet. Payments use x402 USDC on Base.

## Output

Returns a JSON object with a count of matching tenders, the product name, a generated_at timestamp, and a results array of tender objects each containing at minimum a title and buyer_country, plus any additional procurement metadata available for the matched records.
