x402 APIPassing, checked 27 min ago

Call when an agent needs broken JSON repaired deterministically (markdown fences, smart quotes, trailing commas, single quotes, unquoted keys), plus the transforms applied. Use it on model or scraped text that is almost JSON. No LLM. Send JSON {"text":"```json\n{\"a\":1,}\n```"}. Exact $0.002 USDC on Base. Try unpaid POST /v1/sandbox/json-repair first.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://agentshelf.syntexa.ch/v1/json-repair' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"```json\n{\"a\":1,}\n```"}'

# 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://agentshelf.syntexa.ch/v1/json-repair' \
  -H 'content-type: application/json' \
  --data-raw '{"text":"```json\n{\"a\":1,}\n```"}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
