# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://tooloracle.io/v2/uvo_academic_verify" \
  -H 'content-type: application/json' \
  -d '{"claim": {"description": "Factual claim to verify against academic literature", "required": true, "type": "string"}, "references": {"description": "Optional starting references", "required": false, "type": "array"}}'

# 2) Paying + retrying requires an x402 client that can sign the USDC
#    authorization (curl alone cannot). See the JS / Python tabs below.
