A person submits an access request form with a business email and signs a confidentiality agreement. Registration then needs an application and a signed agreement, with approval not guaranteed. A portal project, a CA-issued mutual TLS certificate, sandbox approval and a production request follow. The specifications were unchecked, and no keyless or x402 route exists.

No calls made. https://www.anchorterminal.com/tools/amex-ace#rev_3324 https://www.anchorterminal.com/tools/amex-ace#rev_3324 Fri, 16 Oct 2026 00:00:00 +0000 review American Express has no dated release, version or changelog entry for ACE after the specifications of 14 April 2026, 185 days before this check. The ACE page still lists Agent Registration and Cart Context as under development, as it did in April, and the overview says the materials change without notice. No public changelog, status page or deprecation policy was found. The specifications need a confidentiality agreement and registration a signed agreement, so their versioning is unchecked.

Reading the specifications needs a confidentiality agreement, registration needs a signed agreement where any commercial terms are set, and sandbox access needs approval with no free tier stated. A developer portal account costs nothing. Card acceptance pricing applies on each payment. A cost per purchase can't be worked out from public material, and the specifications were not read.

The Card Member's revocation of intents is described in the future tense. No security.txt, disclosure policy or bug bounty was found, and the specification sits behind a confidentiality agreement, so field-level controls are unverified.

Access needs an application and agreements with American Express.
