Gvnr for businesses
Direct adoption of the substrate — arranged by email, billed by invoice. No outbound sales. Maintainer reads every message at admin@gvnr.dev.
What's available today
Five MCP primitives, live at https://gvnr.dev/mcp and as REST under https://gvnr.dev/v1/*:
- Spend caps — pre-call estimates against per-agent envelopes; deny before the LLM request is sent.
- Rate coordination — per-(agent, provider, model) RPM windows; share one provider quota across many agents.
- Idempotency — dedupe retries on a caller-supplied key; prevent double-charges and double-side-effects from agent retry loops.
- Post-call reconciliation — apply the drift between estimated and actual cost after the LLM responds; keep envelopes honest as model pricing shifts.
- Human approval bridge — pause an agent for a human decision via a mobile-friendly URL; resume on approve, halt on deny or timeout.
Per-account isolation: API keys map to independent Durable Object instances; no cross-account state.
Honest posture: single Cloudflare region (auto edge), solo-maintained, no SLA today. The substrate has been continuously online since 2026-05-18 with 9 MCP tools and 98+ passing tests, but operational guarantees are not contractual until an SLA tier exists.
Billing for direct B2B adoption: SEPA EUR invoicing is arranged manually by email — mail admin@gvnr.dev with expected monthly volume and a billing contact, and you receive an invoice payable into a Luxembourg IBAN (Avvio rail). There is no productized invoice flow today. For self-serve, the same substrate is reachable via the x402 USDC packs on the homepage.
Coming soon
Each item below is on the roadmap but does not have a committed ship date. Asking for one tends to move it up.
P1TypeScript SDK — one-import client over the REST surface; removes the per-agent integration tax. No date.
P2R1 reliability hardening — multi-region durable-object snapshots, Workers-Free compatible. Scoped, deferred under x402-first focus. No date.
P2Trace Store — introspection layer (which agent burned the rate limit between 14:00 and 15:00). Gated on first paying customer ask. No date.
P3SLA tier — gated on a customer who needs and will pay for one. Not on internal aspiration. No date.
