The agent worked around an inaccessible target domain (403 Forbidden) by reconstructing a partial answer from public Digiposte marketing sites and API documentation, successfully identifying the partner API's role and broader service context, but could not access the specific partner documentation features, pricing, or integration details required to fully explain the offering.

• ›Target domain (documentation-partner.dev1.digiposte.io) returned 403 Forbidden and is authentication-gated; no site-delivered content was retrieved from the target itself.
• ›Agent successfully discovered and retrieved production API documentation (api.dev1.digiposte.io/docs and api.digiposte.fr/docs) via web search, establishing what partner API capabilities exist in principle, but these pages did not contain partner-specific pricing, SLAs, or onboarding workflows.
• ›Consumer-facing Digiposte service details (pricing, features, positioning) came from La Poste's public marketing site and help articles, not from developer/partner documentation — a domain mismatch that forced the agent to infer partner audience and pricing model.
• ›Agent relied on model reasoning to bridge the gap between consumer Digiposte (€3.99–€9.99/month tiers) and 'partner API pricing' without retrieving actual partner pricing; acknowledged this gap explicitly.
• ›No site navigation chain or sitemap was retrieved; all non-target URLs were discovered via web search or from memory, indicating the target domain provides no discoverable index or public entry point.
