    Evaluate

    Ready

    The exact service and stable evaluation or access entrypoints are publicly discoverable.

    OpenRouter provides stable public entrypoints for service discovery, including `https://openrouter.ai/llms.txt` and the main API target `https://openrouter.ai/api/v1/chat/completions`.

    Applicable terms are stable, readable, retrievable, and materially complete.

    Eligibility conditions and required inputs are explicit and decidable.

    Price or no-charge status, variables, currency, and material conditions are explicit.

    Verified structured artifacts accelerate discovery of the evaluation surface.

    Web-agent access policy is explicit and verified for the assessed resources.

    Evidence and actions6 signals

    Can an agent decide every material eligibility condition before commitment?

    supported: fresh

    Eligibility conditions and required inputs are explicit and decidable.

    OpenRouter explicitly declares eligibility conditions in its Terms of Service. Users must be at least 18 years old, not previously suspended or removed from the Service, and in compliance with applicable laws and regulations. Users acting on behalf of an entity must have the authority to bind that organization.

    A stable canonical route begins the required access bootstrap.

    OpenRouter provides a stable canonical OAuth PKCE guide and route to initiate user authorization and obtain service access.

    Scoped revocable credentials or delegated authorization have explicit consent and resumption boundaries.

    Evidence and actions5 signals

    Can an agent operate the access controls and safe handoffs deterministically?

    Pay

    Ready

    Charge or no-charge status, currency, recurrence, and material conditions are disclosed.

    OpenRouter discloses US dollars as the base currency for all site and API pricing. It specifies pay-as-you-go token billing passed through from providers with a disclosed 5.5% platform fee, with no minimum spend.

    A documented direct purchase path reaches paid access without a vendor decision point.

    Evidence and actions4 signals

    Can an agent construct checkout, hand off approval safely, and resume?

    supported: fresh

    Current admissible evidence does not resolve this finding.

    OpenRouter documents manual balance top-ups and auto top-up using US dollars. However, the retained evidence does not document an API or protocol flow for an agent to deterministically construct checkout, hand off approval safely, and resume.

    Provision

    Ready

    Provisioning is machine-triggerable or follows deterministically from an allowed handoff.

    API key provisioning is machine-triggerable via a POST request to https://openrouter.ai/api/v1/keys using Bearer token authentication.

    Credentials, grants, or configuration are delivered through a documented agent-usable flow.

    A synchronous success response returns a usable created resource or access material; otherwise asynchronous work exposes progress, terminal state, reconciliation, and a documented bound.

    Evidence and actions3 signals

    Can usable access material be delivered securely to an authorized agent?

    supported: fresh

    Credentials, grants, or configuration are delivered through a documented agent-usable flow.

    OpenRouter provides an API endpoint to create API keys, returning the plaintext key directly in the synchronous response for agent use.

    Operate

    Limited

    Safe failure handling is documented only partially.

    OpenRouter documents typed error codes across streaming and non-streaming responses and a Retry-After header section; the selected quotes do not establish idempotency or reconciliation semantics.

    Only part of the credential lifecycle is agent-operable.

    Every essential target has a stable documented agent-usable interface alternative.

    Request-time authentication is documented and usable under scoped agent authority.

    Essential operations have stable readable request, response, and effect semantics.

    A verified agent-native interface covers the declared assessment targets.

    Evidence and actions6 signals

    Is an agent-native protocol interface verified against the essential targets?

    supported: fresh

    A verified agent-native interface covers the declared assessment targets.

    OpenRouter provides an MCP server interface (https://mcp.openrouter.ai/mcp) that connects AI tools over MCP to pull live model, pricing, credit, and ranking data, search docs, and send test messages.

    Can an agent manage credential expiry, rotation, revocation, compromise, and recovery?

    supported: fresh

    Only part of the credential lifecycle is agent-operable.

    What would improve this stage

    • Document applicable structured errors, retry, cancellation, and reconciliation semantics.
    • Provide scoped expiry, rotation, revocation, compromise, and recovery operations.

What works

  • Evaluate: The exact service and stable evaluation or access entrypoints are publicly discoverable.
  • Sign up: A stable canonical route begins the required access bootstrap.
  • Pay: Charge or no-charge status, currency, recurrence, and material conditions are disclosed.
  • Provision: Provisioning is machine-triggerable or follows deterministically from an allowed handoff.

What blocks agents

No stage is established as blocked.

Where autonomy is limited

  • Operate: Safe failure handling is documented only partially.

What this grade establishes

14 of 14 graded signals have current supporting evidence. 0 of 5 additional barrier checks are verified.Unknown checks are not a pass or a confirmed blocker. This report is not proof of an end-to-end purchase or service session.

How the grade is derived

A through C grades count Limited stages; D and F reflect Blocked stages by lifecycle severity.

Coverage is complete only when every graded signal has supported, fresh, non-conflicting evidence. Barrier and informational signals do not change coverage; only fresh, supported barrier values that passed their admission evidence rule participate in stage outcomes.

Each stage takes its worst graded signal or verified barrier. A fresh, supported mandatory barrier that passed its admission evidence rule can block that stage; incomplete or stale barrier evidence remains context only. The overall grade is derived from the five stage states.
