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.
Protocol-first agentic infrastructure
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.
from patchr import Patchr
client = Patchr(api_key="pk_live_...")
# Audit a disputed claim
result = client.run(
request="Review claim #4821",
workflow="resolve",
evidence=["photos.zip", "policy.pdf"]
)
card = result.proof_card
print(card.evidence_status) # "verified"
print(card.confidence) # 0.87
print(card.recommended_action) # "safe_to_settle"Proof Card Output
The protocol layer for teams building on
Build
Read the manifest, pick Python or Node.js, then validate the surfaces your agent will use before writing any logic.
Resolve
Classify contradictions, identify missing proof, set confidence, and emit a reviewable next-action record.
Bridge
Route connector work, MCP tools, A2A delegation, and Proxy handoffs through scoped capability boundaries.
Prove
Every run ends with a proof card, vault record, receipt, and event trail that can be cited, shared, or escalated.
Protocol primitives
Public routes, schemas, manifests, events, and handshakes — so agents discover what they're allowed to do before they act, not after they break something.

Audit exports
Discover and rank high-value signals across fragmented markets, sources, and evidence trails.
Validate chronology, prune unsafe paths, reconcile contradictions, and emit reviewable records.
Connect external systems through scoped connector contracts, MCP tools, APIs, and webhooks.
Preserve durable conversation state across email, chat, messaging, telephony, CRM, and callbacks.
Coordinate formal workspaces with stakeholders, deadlines, status timelines, evidence, and exports.
Suspend autonomy for human judgment, regulated handoff, logistics, messaging, and proof capture.
Prepare settlement with mandates, proof-of-value, receipts, and adapter-neutral payment rails.
Workflow templates
Each template ships evidence status, confidence, open questions, and a shareable proof card — without hiding the domain logic that produced them.
Browse all seven templatesfindBestFitUnify fragmented discovery, rank source-backed options, and generate the next best action.
auditDisputedClaimBuild an evidence map, identify contradictions, request missing proof, and package a proof card.
coordinateHumanProcessRoute human logistics, collect outcome proof, and resume Resolve with a source-of-truth callback.
For startup ops teams
Four operator-packaged templates — procurement, due diligence, compliance export, and decision logging — each ending with a proof card your finance, legal, or compliance team can use directly.
Vendor due diligence in 1 day.
Source-bound vendor evidence, policy scoring, handoff trail, ROI summary, and a sealed proof pack.
Decision LogEvery option, every rejected path — preserved.
Log the full candidate set, rationale, and pruned paths in a portable record compatible with decision ledgers.
Compliance AuditTask record → audit-ready report.
Seal any completed task as a proof pack for a regulator, board, or legal review — one call, no write-up.
ProcurementHunt, verify, pay — receipt at the end.
Issue a spend mandate. The protocol enforces policy, executes settlement, and returns a finance-ready receipt.
Developer quickstart
Read the manifest, validate compatibility with a handshake, then run. Every surface is versioned and machine-readable — no Patchr-specific wrapper required.

Sandbox
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 sandboxOrchestrator 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.
Production use cases
Turn screenshots, message threads, policies, and payment records into a source-bound review file a legal team can trust.
Learn moreGive LLM pipelines explicit contracts for when to call tools, when to stop, when to escalate, and how to prove they got it right.
Learn moreRegulated handoffs, human proxy missions, and compliance-grade audit exports — all in one repeatable protocol path.

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

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

"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
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.
Score a vendor before you sign with policy rules, source-bound evidence, and unresolved questions made explicit.
Unify procurement, compliance, legal, finance, and operators around one proof-backed vendor case file.
Close with citations, decision log, handoff trail, ROI summary, and restraint guidance for the next action.
