PRODUCT · FORGE API
Wire-compatible. Sovereign-hosted. Evidence-bearing.
Drop in to your existing OpenAI or Anthropic SDK. Change one base URL. Gain a cryptographic receipt on every inference, EU-residency by default, and constitution-bound endpoints.
FROM PROMPT TO PROOF.
// Switch from OpenAI to Forge — change ONE line.
- baseURL: 'https://api.openai.com/v1'
+ baseURL: 'https://api.forge.openstatestack.solutions/v1'
// The response now carries one extra field:
+ completion.proof.receipt
+ → { id, anchor, constitution, request_hash, response_hash, residency, … }CAPABILITIES
Nine guarantees. One base URL switch.
OpenAI-wire compatibility
/v1/chat/completions, /v1/completions, /v1/embeddings, /v1/images — same shapes.
Anthropic-wire compatibility
/v1/messages schema — same shapes.
Cryptographic receipts
Every response includes proof.receipt with a chain-anchored hash.
Constitution-bound API keys
Each key is bound to a named agent constitution; out-of-scope calls refused.
EU-residency by default
Inference runs in EU regions; per-municipality residency available.
ZKP-encrypted payloads
Optional payload encryption that survives the inference round-trip.
Audit-friendly billing
Every call has a receipt that procurement can read alongside the invoice.
Forge-native models
forge-conductor-1 and forge-conductor-1-mini — tuned for government workloads.
Bring-your-own model
Hosted in your jurisdiction; receipts and constitutions still apply.
