How to call it

POST https://api.17711.xyz/registry/url-extract-service/v1/url-extract/get_structured_data

Each call costs $0.02 in USDC on Base, paid with the request over x402.

Run a free test callOne unpaid request, the way an agent sends it. You see the payment challenge it gets back. Nothing is charged.

Example request

From the listing.

POST https://api.17711.xyz/registry/url-extract-service/v1/url-extract/get_structured_data
content-type: application/json

{
  "max_age_seconds": 0,
  "question": "string",
  "schema": null,
  "url": "string"
}

Parameters

ParameterTypeRequiredDescription
max_age_secondsinteger or nullNoThe oldest answer you accept, in seconds. Omit it for the default (an identical question about the same page up to 1 hour old); `0` forces a fresh read of the page and a fresh answer. The response always says how old it is. Default: null.
questionstringYesWhat to extract or answer, in plain language, e.g. "list the pricing plans with their name and monthly price in USD".
schemaanyNoOptional JSON Schema the answer must satisfy. When given, the answer is validated against it and automatically corrected where a safe fix exists (type coercion, missing defaults, out-of-range numbers, unknown properties); anything that cannot be fixed is reported in `remaining_issues`. Omitted = a … Default: null.
urlstringYesAddress of the web page to read (`http` or `https`).

Example response

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://api.17711.xyz/registry/url-extract-service/v1/url-extract/get_structured_data' \
  -H 'content-type: application/json' \
  --data-raw '{"max_age_seconds":0,"question":"string","schema":null,"url":"string"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://api.17711.xyz/registry/url-extract-service/v1/url-extract/get_structured_data' \
  -H 'content-type: application/json' \
  --data-raw '{"max_age_seconds":0,"question":"string","schema":null,"url":"string"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
