POST /v1/txintent

unprobed

Tx Intent Classifier: decodes the REAL intent of an on-chain transaction (Base/Ethereum) and returns an Ed25519-signed risk verdict (safe/review/suspicious/dangerous). Catches unlimited approvals, opaque selectors, value-to-contract, reverted tx. POST {"tx_hash":"0x..","chain":"base"} or {"to":"0x..","data":"0x.."}.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://api.hergertsynthora.com/v1/txintent' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
