# OpenID Connect Discovery Endpoint Summarizer

> OpenID Connect Discovery Endpoint Summarizer is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches and summarizes an issuer's OpenID Connect discovery document, extracting endpoints, supported scopes, algorithms, and capabilities for auth integration pre-checks.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability openid-connect-discovery-endpoint-summarizer-a68e612d
```

Example prompt: Can you fetch and summarize the OpenID Connect discovery document for https://accounts.google.com — I want to see the token endpoint, supported scopes, grant types, PKCE methods, and signing algorithms before I build my auth integration.

## When to prefer this

Use this endpoint when you need a quick, structured summary of an OIDC provider's capabilities before building or debugging an auth integration. Prefer it over manually fetching and parsing /.well-known/openid-configuration yourself, especially in agentic workflows where you need clean structured output about supported scopes, algorithms, and endpoints. Ideal for pre-integration checks, security audits of auth configurations, or comparing identity providers.

## Known failure modes

- Issuer URL not provided or malformed — returns error with missing parameter details
- Target server does not expose a /.well-known/openid-configuration endpoint — returns fetch or 404 error
- Target server is unreachable or times out — returns connectivity error
- Discovery document exists but is malformed or non-compliant JSON — returns parse error
- Rate limiting or payment failure at $0.01 USDC per call — returns 402 payment required

## How this service works

OpenID Connect discovery for an issuer: fetches /.well-known/openid-configuration and summarises issuer, authorization/token/userinfo/jwks/end-session/registration endpoints, supported scopes, response types, grant types, PKCE methods, signing algorithms, claims and subject types. Integration pre-check for auth agents. $0.01 per issuer.

## Output

A structured summary of the issuer's /.well-known/openid-configuration including: issuer identifier, authorization/token/userinfo/JWKS/end-session/registration endpoint URLs, supported scopes, response types, grant types, PKCE code challenge methods, ID token signing algorithms, supported claims, and subject types.
