GET https://aeml-x402.zeabur.app/gauge/ruler · 1 observation
Add-on, the official ruler: the band and threshold ladder published by the source agency, its classification, and distance-to-action. NOT every line has an official ruler - pure market quotes do not. When it does not, you get 422 with no_charge:true and reason:no-ruler-for-this-line and you are NOT billed. Never a bag of nulls you paid for. Every record carries an offline-recomputable record_hash.

GET https://aeml-x402.zeabur.app/pay/tier2 · 1 observation
Tiered payment receipt (tier 2): pay once with x402 and get back a short-lived receipt token that /pay/verify checks for you. The tier is fixed by the path - you do not send it. Optional ?ref= carries your own opaque reference, such as a query hash, straight through to the receipt. This mints a receipt rather than returning data, so there is no lookup that can come back empty.
