Does WaveSpeedAI sign your AI output? What its terms say

Does WaveSpeedAI attach a C2PA manifest or a watermark?

Nothing in WaveSpeed's documentation mentions Content Credentials, C2PA or output marking, as searched on 12 October 2026. The platform does sell the opposite: an AI watermark remover, described on its own page as a tool that "estimates what could plausibly appear behind an overlay", offered for "images or videos you own or are authorized to modify". Section 13.4 of the terms notes that the law applying to the services "is evolving rapidly in various jurisdictions". The operating entities are a Singapore company and a Hong Kong company.

What do WaveSpeedAI's terms say about who is responsible?

The terms were last updated on 28 September 2026. Two clauses matter here:

"Customer is responsible for their use of the Services, including any content generation that violates any Laws." — WaveSpeedAI Terms of Service, Section 8.1, Acceptable and Restricted Use, read 12 October 2026

"Customer is solely responsible for evaluating, validating, and verifying all Outputs." — WaveSpeedAI Terms of Service, Section 13.5, Disclaimer, read 12 October 2026

The terms also prohibit "misrepresenting or misleading people into believing that the use of the Services or Outputs is human-generated" (Section 8.3). That is a rule about deception, not a marking requirement; a signed manifest in your own name is the surest way to comply with it.

So who is the provider under Article 50(2)?

The Commission's guidelines on Article 50, adopted on 20 July 2026, treat a business that integrates a model by API into its own user-facing system as the provider of that AI system, answerable under Article 50(2) for what the system generates (our reading of 8 October 2026, shared by the law-firm notes we have seen). WaveSpeedAI's terms point the same way. So if your users see images, audio or video that WaveSpeedAI generated for you, the marking obligation is yours, and it is not discharged by anything WaveSpeedAI attaches.

What this means if you generate through WaveSpeedAI

Outputs are unmarked and the terms are explicit that unlawful generation is yours. The watermark-remover product is worth knowing about for a different reason: under California's AI Transparency Act, stripping provenance is itself a violation, and the EU Code of Practice expects providers to prohibit removal in their terms.

SignUnder is built to sit in front of APIs like this one and sign every output under your own name, with an invisible watermark and a public verification page; it is pre-launch, and the waitlist is on the homepage.
