XGuard●
PUBLIC SOURCES → USABLE OUTPUT

Structured product offer comparison

Extract and normalize Schema.org offers from up to three supplied product pages; group matching identifiers and currencies with source evidence.

Try extraction free

No account. No API key. 0.006000 USDC per execution.

ONE REQUEST TO START
curl https://api.xguardgate.com/v1/execute \
  -H 'content-type: application/json' \
  -d '{"intent":"Extract product offers","urls":["https://www.adafruit.com/product/50"]}'

The demo runs the real parser on labelled sample HTML.

What comes back

Validated offer fields and comparable groups; missing identifiers and unsupported pages are explicitly reported.

When to use it

Compare machine-readable offers across supplied merchant pages without writing multiple fetchers, parsers and matching rules.

Limits

Latency: measured figures are not yet available; source timeouts are bounded. No SLA.

Less work between intent and result.

01 / DESCRIBE

Tell us the outcome.

Send pages, product URLs or feeds. For a technology digest, the source set is already provided.

02 / AUTHORIZE

See the exact price.

A paid request returns a signed 402. Your funded x402 client authorizes that request and retries it automatically.

03 / USE

Get a consistent answer.

Receive normalized records, coverage, source digests and a signed receipt. Identical paid retries recover the stored outcome.

A signed source digest records what was observed. It does not prove that an article is true, a merchant price is current at checkout, or multiple pages are independent sources.

Bring your agent.
