AWS Free Tier
Cryptographic identity and tamper-evident audit evidence for autonomous AI agents. W3C DID + Verifiable Credentials, on-chain anchored. Supports EU AI Act Article 12 logging. Verification is free.
Overview
The problem
A shared API key identifies the account, not the acting agent. It leaves no per-action record tied to a verifiable identity, and logs can be edited or rotated. When an auditor asks what an agent was authorized to do and what it actually did, there is no answer that holds up.
What MolTrust does
Agent identity *a W3C DID per agent: registered, signed, resolvable.
Authorization *the Agent Authorization Envelope (AAE) records MANDATE, CONSTRAINTS and VALIDITY as a signed credential. Published as IETF Internet-Draft draft-kroehl-agentic-trust-aae-00.
Evidence *SHA-256 evidence hashes anchored on Base L2. Tamper-evident by cryptographic proof, not by policy.
Export *signed audit bundle (PAdES-B-LT) covering any period, verifiable independently.
Verification is free, always
Anyone can verify an agent's identity, credentials and behavioural score without an account, an API key, or a payment. Only agent operators pay. This is deliberate: a trust layer that charges the verifier does not get adopted.
No lock-in, no custody
Every credential is a standards-compliant W3C Verifiable Credential. Auditors validate signatures with any DID-conformant tool, no MolTrust software or account in the verification path. MolTrust does not hold your evidence long-term: the on-chain anchor holds the proof, you hold the exported file. Operational retention is 12 months.
Scope
MolTrust is a deterministic cryptographic protocol layer, comparable in role to TLS or PKI. It supports EU AI Act Article 12 logging requirements with cryptographic provenance. Full logging responsibility under Article 12(1), conformity assessment under Article 43, and compliance responsibility under Article 16 remain with the AI-system provider. MolTrust does not issue compliance certificates and does not provide legal advice.
Standards
W3C DID Core and Verifiable Credentials v2, IETF Internet-Draft (AAE), DIF Universal Resolver driver , aligned with the Singapore IMDA Model AI Governance Framework for Agentic AI (2026), Circle Alliance member, technical paper: arXiv 2605.06738
Highlights
- Verifiable agent identity, a W3C DID per agent with a signed authorization envelope recording MANDATE, CONSTRAINTS and VALIDITY. Published as an IETF Internet-Draft, not a proprietary primitive. Any DID-conformant tool can resolve and verify it.
- Audit evidence that outlives the vendor, SHA-256 hashes anchored on Base L2, exported as a signed PDF (PAdES-B-LT). Your auditor verifies it independently: no MolTrust account, software, or API call in the verification path. Supports Article 12 logging.
- Verification is free for everyone, only agent operators pay. Any party can verify an agent's identity, credentials and score without an account, a key, or a payment. Standards-based on W3C DID, no vendor lock-in.

Dimensions summary
This listing offers a single Free dimension with no charge. You get access to every verification endpoint and can create an API key using only an email, with no credit card required. Registration includes a starting pool of credits, and cryptographic identity plus public-ledger anchoring are covered at no cost. Because there is one free option, pricing does not scale across tiers or usage add-ons here. The Free dimension suits proof-of-concept work and internal testing. There are no paid steps or quantity settings to configure within this Marketplace offering.
Top-of-mind questions for buyers
Credits fund your API calls. Most calls cost one to two credits each. Reads like health checks, DID resolution, and pricing lookups are free. Credential issuance is heavier and costs more. Registration includes 100 credits, which are transactional with no monthly quota.
The free credits are transactional with no monthly refill. When the balance runs low, an agent pre-funds more credits itself by paying USDC on Base through the x402 rail. There is no monthly quota and no human top-up step in this free dimension.
The free tier covers every verification endpoint, an email-only API key, 100 starting credits, and public-ledger anchoring on Base L2. Signed audit-bundle export (PAdES-B-LT) is not part of the free dimension. Evidence retention runs 12 months, held by the on-chain anchor and your exported file.

Usage instructions
A2A agent card
<https://api.moltrust.ch/.well-known/agent.json>
MolTrust publishes a Google A2A-compatible agent card with trust extensions: DID, reputation, and capability data. Listed on a2aregistry.org.
JSON-RPC endpoint
<https://api.moltrust.ch/a2a>
What other agents can do
Resolve a MolTrust DID, request a trust score, verify a credential, and check an authorization envelope (AAE) — all without an account or key. Verification is free for every party.
Trust extensions
The agent card carries the agent's DID, its behavioural trust score, and the signed authorization envelope under which it operates. Any counterparty can verify these independently against the on-chain anchor on Base L2, with no call to MolTrust in the verification path.
