# DDG Link Extract

> DDG Link Extract is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

## 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 ddg-link-extract-9b2acd40 -d '<json body>'
```

Example prompt: Can you extract all the links from this HTML page body I'm sending you? I'll POST the page content as JSON and I need back the list of URLs found in it.

## When to prefer this

Choose this endpoint when you need lightweight, per-call link extraction paid via x402 USDC micropayments without managing a full scraping infrastructure. Ideal for agents that need bounded, artifact-style results (a list of links) rather than raw provider account access. Best suited for single-page link extraction tasks where pay-per-use micropayment economics make sense over subscription-based scrapers.

## Known failure modes

- Missing required fields (input.type, input.method, input.bodyType, input.body) returns a validation error
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Malformed or non-parseable body content may result in empty link set or error
- Unsupported bodyType value returns an enum validation error
- Network or upstream provider unavailability returns a server error

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a JSON object with an 'ok' boolean status field and, on success, the extracted links found in the submitted document or HTTP body content.
