Proof, Indicio, and deepidv compared on AI agent identity: x401 authorization evidence, verifiable credential rails, and the decision plane that scores both.
An operational engineering analysis evaluating deepidv, Proof, and Indicio as agent authorization becomes a product category: a protocol-and-wallet play, a verifiable credential infrastructure play, and the decision plane that has to score whatever both produce.
The three answer different clauses of the same sentence. Proof wants to be how an agent proves it was authorized, per transaction, with signed evidence. Indicio wants to be the credential rails an ecosystem issues and verifies agent identities on. deepidv verifies the humans at the root and decides, at action time, whether this credential, this mandate, and this context add up to a yes. Buyers assembling an agent program usually need all three clauses, and the integration order matters more than the logos.
| Capability | deepidv | Proof | Indicio |
|---|---|---|---|
| Human principal verification | Core: documents, biometrics, liveness, screening | Identity verification heritage from notarization platform | Relies on issuer ecosystem's proofing |
| Per-action authorization evidence | Arc mandates: scoped, signed, logged | Core: x401 evidence objects, agent wallet | Credential presentations, proof requests |
| Open protocol and standards posture | Consumes mandates and VCs as evidence | x401 open HTTP protocol, x402 adjacency | W3C VCs, DIDComm, open-source stack |
| Agent-to-service integration surface | Decision plane APIs and gateway | MCP server across major AI assistants | SDKs and mediator infrastructure |
| Transaction-time risk scoring | Core: fused identity, device, velocity signals | Signature and chain validation | Verification of credential status |
| Regulatory evidence records | Core: per-decision, method-named, exportable | Signed authorization trail per transaction | Depends on relying party's logging |
deepidv's role in an agent program is the one it plays everywhere else: verify the human to enrollment grade, then treat every artifact the agent presents, an x401 evidence object, an AP2 mandate, a verifiable credential from anyone's rails, as evidence to validate and weigh, not as a verdict. Arc binds agent actions to verified principals through scoped, expiring mandates, the decision plane fuses signature checks with device, velocity, and identity risk at transaction time, and every decision writes the method-named record a regulated relying party must keep. The boundary runs the other way too: deepidv does not publish an open agent protocol or operate credential mediator infrastructure, and programs betting on a particular protocol's network effects need the protocol's own owner at the table.
Proof arrives with an underrated asset: a decade of making signed, legally consequential records from its notarization business, now aimed at agents. x401, published in June and extended this week with an agent identity wallet and a production MCP server, produces exactly the artifact the market lacks, portable proof of who an agent represents and what it was authorized to do, with device biometrics in the human loop and x402 payments one layer down. The framing device, the Agent Evidentiary Gap, is the right diagnosis. The diligence questions: production claims are the company's own, the protocol's network is young and its governance is effectively single-vendor today, acceptance depends on relying parties choosing to verify x401 objects, and the evidence is only as good as the principal verification behind the wallet, which is the inheritance rule no protocol escapes.
Indicio comes from the decentralized identity world, W3C verifiable credentials, DIDComm messaging, open-source agent frameworks, and its answer to agent identity is infrastructural: issue agents and their principals credentials on rails any party can verify, with its Proven platform carrying the commercial offering and its public work asking who verifies the verifier. The strengths are real: standards alignment, no single-vendor lock on the credential format, and a mediator architecture built for machine-to-machine presentation. The questions are the ecosystem kind: credential quality inherits the issuer's proofing, which Indicio enables but does not perform; revocation and status infrastructure must be operated by someone; and rails without a decision layer verify that a credential is valid, not that honoring it is wise.

Book a DemoRun the scenario every agent program eventually faces: a customer disputes a 3,000 dollar purchase their agent made. On Proof's stack alone, the platform produces a signed x401 evidence object, this wallet authorized this transaction, which answers the signature question and leaves the enrollment question open, who verified the human behind the wallet, and against what documents. On Indicio-style rails alone, the credentials check out as validly issued and unrevoked, which answers format and status and says nothing about whether the risk picture at purchase time warranted honoring them. On deepidv alone, the principal's verification, the mandate's scope, and the transaction-time risk score are all on file, and the program still benefits from portable evidence formats other parties can countersign. Composed, the dispute closes in minutes: enrollment-grade identity at the root, a standard credential carrying it, a signed per-action object, and a decision record explaining why the yes was reasonable. The moral for buyers is the stack's: protocols and rails make authorization expressible, and only verification plus decisioning makes it true.
Run this test on deepidv. Book a demo and bring your own dispute scenario.
Proof produces per-transaction authorization evidence through its x401 protocol and agent wallet; Indicio provides verifiable credential infrastructure for issuing and verifying agent identities; deepidv verifies the human principal and scores credentials, mandates, and risk at action time with full decision records.
An open HTTP protocol, introduced in June 2026, for verified AI agent identity and signed transaction authorization, extended in October with an agent identity wallet and an MCP server, and designed to sit beside the x402 payment protocol.
Standards-based rails: W3C verifiable credentials and DIDComm let any party issue, present, and verify agent and principal credentials without a single vendor controlling the format, with Indicio supplying the infrastructure and tooling.
Mostly they compose. A program can verify principals with deepidv, carry identity on Indicio-style rails, and emit Proof-style per-action evidence. Overlap appears mainly at the wallet and at relying-party integration, where buyers should pick one source of truth per decision.
The enrollment behind them: which party verified the human principal, against what evidence, how recently, and with what liveness. A formally valid credential from a weak enrollment is the primary fraud vector in agent systems.
