GET /chain/l1-fee
unprobed
The L1 data-availability fee an OP-stack transaction pays on TOP of its L2 execution gas — usually the larger half of the bill, and the half that every ordinary gas estimator leaves out. Pass data=0x... and get the real L1 fee for THAT transaction; pass bytes=N and get a representative quote. The figure comes from the chain's own GasPriceOracle.getL1Fee (0x420...0F), not from a reimplemented form…
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares GET. 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.
