How to call it

POST https://api.17711.xyz/registry/extract-correct-service/v1/extract-correct/parse_json

Each call costs $0.006 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/extract-correct-service/v1/extract-correct/parse_json
content-type: application/json

{
  "schema": null,
  "text": "string"
}

Parameters

ParameterTypeRequiredDescription
schemaanyNoOptional JSON Schema to validate the extracted value against and auto-correct where a bounded, deterministic fix rule applies. Omitted = extraction only, no validation. Default: null.
textstringYesFree-form or messy text to extract structured JSON from -- already-valid JSON, JSON wrapped in prose or a markdown code fence, or malformed JSON (trailing commas, single-quoted strings, unquoted keys, a truncated array/object).

Example response

The provider's example. We can't check it without paying.

  "applied_fixes": [
    {
      "detail": "string",
      "path": "string",

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.006.

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/extract-correct-service/v1/extract-correct/parse_json' \
  -H 'content-type: application/json' \
  --data-raw '{"schema":null,"text":"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/extract-correct-service/v1/extract-correct/parse_json' \
  -H 'content-type: application/json' \
  --data-raw '{"schema":null,"text":"string"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
