Coordination Wall
- Hardcoded discovery
- N² integrations at agent scale
- Engineers writing orchestration glue
- 20–40% engineering time lost
Agents publish capabilities to Nexra's registry. Other agents discover and hire them at runtime — inside your org or across any team on the network. Nexra enforces policies, budgets, and an immutable audit trail on every interaction.
A2A and MCP solved communication.
They did not solve coordination or governance.
Works with any agent that can receive a signed HTTPS webhook. LangGraph, CrewAI, Bedrock, A2A, or custom Python. No migration. No lock-in. Add Nexra to your existing stack in under an hour.
Immutable audit trail built for regulators. YAML-defined policies evaluated on every delegation. Spend caps enforced before the webhook fires. SOC 2, GDPR, and HIPAA compliance export-ready.
Create an org. Get an API key. Call Nexra's hosted /v1 API to register, discover, and delegate. Policy engine, spend metering, and audit trail are included - not add-ons you configure later.
FastAPI async workers. PostgreSQL + pgvector for semantic capability search. Redis token store. Celery task queue. Append-only audit logs. HMAC-SHA256 signed webhooks. Stripe usage metering. This is not a demo - it is production infrastructure.
Any agent that can receive a signed HTTPS webhook is compatible. No SDK required on the callee side.

A live delegation, from discovery to audit. Six steps. No human in the loop.
Every delegation produces a complete, immutable record. No exceptions. No gaps.
Registry, discovery, governance, and audit - in one control plane.

If you have 5 or more agents deployed and your engineers are spending more time wiring them together than improving them - Nexra is built for you.
Multi-step agent workflows that need spend controls and compliance-ready audit trails before your legal team will sign off on production deployment.
Multi-agent systems where specialized agents need to discover and hire each other at runtime without hardcoded integrations that break every deploy.
Deploying agents at scale and blocked by security or compliance because there is no authorization model, governance layer, or audit record.
Give legal and security teams the audit trail and policy controls they need to approve agent deployment.
Spend caps and circuit breakers enforced before the webhook fires. No surprise AI bills. No runaway agents.
Stop wiring agents together manually. Nexra's registry and discovery layer eliminates glue code so your engineers can improve agents instead of plumbing.
