Protocol-first agentic infrastructure

Build agents that explain themselves.

Give your agents contracts to work within, evidence maps to reason over, and regulated handoffs when a human needs to decide. Every run ends with a portable proof card.

Build

Start with SDKs and contracts

Read the manifest, pick Python or Node.js, then validate the surfaces your agent will use before writing any logic.

Resolve

Map evidence, prune unsafe paths

Classify contradictions, identify missing proof, set confidence, and emit a reviewable next-action record.

Bridge

Connect people and systems

Route connector work, MCP tools, A2A delegation, and Proxy handoffs through scoped capability boundaries.

Prove

Close with a portable case file

Every run ends with a proof card, vault record, receipt, and event trail that can be cited, shared, or escalated.

Protocol primitives

One contract surface. Every domain covered.

Public routes, schemas, manifests, events, and handshakes — so agents discover what they're allowed to do before they act, not after they break something.

Hunt

Discover and rank high-value signals across fragmented markets, sources, and evidence trails.

Resolve

Validate chronology, prune unsafe paths, reconcile contradictions, and emit reviewable records.

Bridge

Connect external systems through scoped connector contracts, MCP tools, APIs, and webhooks.

Channels

Preserve durable conversation state across email, chat, messaging, telephony, CRM, and callbacks.

Cases

Coordinate formal workspaces with stakeholders, deadlines, status timelines, evidence, and exports.

Proxy

Suspend autonomy for human judgment, regulated handoff, logistics, messaging, and proof capture.

Pay

Prepare settlement with mandates, proof-of-value, receipts, and adapter-neutral payment rails.

Developer quickstart

Integrate through contracts, not internals.

Read the manifest, validate compatibility with a handshake, then run. Every surface is versioned and machine-readable — no Patchr-specific wrapper required.

Sandbox

No API key needed to start.

Send a request and watch the orchestrator coordinate HUNT, RESOLVE, PROXY, and PAY in real time — with a live proof card at the end.

Open sandbox

Orchestrator streaming

Watch domain events arrive in real time as the run progresses.

Domain handoffs

See exactly which agents were called, in which order, and why.

Shared tool traces

Inspect every tool call — browser reads, map lookups, image parsing.

Proof-card output

Every run closes with evidence status, confidence, and a portable record.

What builders say

Proof-first, from day one.

Share your experience

"Patchr gives our AI workflows the audit trail our compliance team actually trusts. Every run ends with evidence we can share with legal."

Ho

Head of Engineering

Fintech startup

"We replaced three custom middleware services with Patchr's protocol layer. The proof card output alone saved us weeks of documentation."

SA

Senior AI Engineer

Enterprise SaaS team

"The sandbox let us prototype a disputed-claim workflow in an afternoon. By the next day we had the proof card integrated into our support tool."

Workflows - Vendor Due Intelligence

Vendor due diligence in one day, sealed in a proof pack.

Patchr turns vendor intake, policy checks, source-bound evidence, human follow-up, and approval rationale into one inspectable record. Procurement, compliance, legal, finance, and operators work from the same proof-backed case file instead of fragmented screenshots and spreadsheet comments.

Commercial wedge

Score a vendor before you sign with policy rules, source-bound evidence, and unresolved questions made explicit.

Cross-functional record

Unify procurement, compliance, legal, finance, and operators around one proof-backed vendor case file.

Sealed proof pack

Close with citations, decision log, handoff trail, ROI summary, and restraint guidance for the next action.
