description: 'Rainbow — formerly Riverse, whose riverse.io domain now 301s to rainbowstandard.io — is a carbon crediting programme
  and registry that certifies and issues Rainbow Carbon Credits (RCCs) from engineered carbon removal and greenhouse-gas reduction
  projects across biochar, BiCRS/BioCCS, enhanced rock weathering, ex-situ mineralization, biogas from anaerobic digestion,
  biobased construction materials, battery second life and electronics refurbishment. The programme is ICVCM Core-Carbon-Principles
  approved, ICROA endorsed, approved as a Frontier credit issuer, and runs EU CRCF-compliant plus CORSIA and Paris Agreement
  Article 6 crediting tracks. It operates two platforms: Arc (arc.rainbowstandard.io), the project-developer certification
  and MRV platform launched October 2025, and the public Rainbow Registry (registry.rainbowstandard.io) where every project,
  credit block, serial number and retirement is published. Its public surface is a 163-page GitBook documentation hub of standard
  rules, procedures, methodologies, fees and governance policies, served with a real llms.txt and a Content-Signal AI-usage
  declaration. No OpenAPI, AsyncAPI, GraphQL SDL, SDK, MCP server or A2A agent card is served on any Rainbow host; the only
  public acknowledgement that an API exists at all is a single line in the published fee schedule confirming that API connections
  carry no additional cost.'

  detail: Rainbow's own published fee schedule confirms an API exists — "Rainbow does not charge additional costs for retirement,
    transfers or API connections" — but the connection is only available to Arc/Registry account holders and not one of the
    163 public documentation pages describes an endpoint, base URL, auth model or spec.
