# wAILand Funding Changes

> wAILand Funding Changes is a paid API for AI agents from wailand.tailf99551.ts.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns a delta feed of changes to EU/DACH public funding calls since a given date, including new calls, deadline moves, amount edits, title edits, and closures.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 wailand-funding-changes-0aa9c338
```

Example prompt: Show me everything that changed in EU and DACH funding calls since August 24, 2026 — any new calls, deadline moves, amount or title edits, and anything that closed.

## When to prefer this

Use this endpoint when an agent already holds a list of funding opportunities from /v1/opportunities and needs to detect what has changed since a known date — new calls, deadline shifts, closures, or edits. It is purpose-built for incremental monitoring workflows over EU and DACH public funding portals, with a daily snapshot archive from May 2026. It is not suited for retrieving the full current list of open calls (use /v1/opportunities) or for non-EU/DACH funding sources.

## Known failure modes

- Missing required 'since' parameter returns a 400 error
- Invalid date format for since/until returns a validation error
- Requesting a source not in the allowed enum returns a 400
- No changes found for the given filters returns an empty list
- Data for DACH sources may be sparse if crawl did not reach all pages
- Changes before 2026-05 are not in the archive; field-level changes before 2026-08-24 unavailable

## How this service works

Call this when an agent holds EU/DACH funding calls (see /v1/opportunities) and needs what changed since a date: new calls, deadline moves with extraction basis, amount or title edits, and deadline-crossed closures, each dated to the daily snapshot that first showed it. Call /count (free) first: ftop_sedia changes most days, each DACH source about weekly. Own archive since 2026-05; field changes from 2026-08-24; DACH limited to crawled pages. Filters: since (required), until, source, kind.

## Output

A list of funding change events, each specifying the event kind (appeared, closed, deadline_changed, amount_changed, title_changed), the affected funding call, the before/after values, and the snapshot date on which the change was first observed. Sourced from EU (ftop_sedia) and DACH portals (cascade_funding, aws_austria, ibb_berlin, l_bank_bw, lfa_bayern, nrw_bank).
