How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the detected scheme name (e.g. 'bearer', 'basic'), a boolean indicating whether a credential is present, a redacted credential flag, the SHA-256 hash of the input for auditability, a count of external calls made (always 0), and a retention flag (always false). Includes operation name and schema version for traceability.
Example use cases
Validating API gateway auth headers
“I have this raw Authorization header from an incoming request: 'Basic dXNlcjpwYXNz' — can you tell me what scheme it uses and whether a credential is actually present in it?”
Debugging a misconfigured auth token
“This Authorization header came back from our proxy and I'm not sure if it's a bearer token or something else: 'Token abc.def.ghi' — what scheme is this and is the credential there?”
Auditing third-party request credentials
“Before I forward this API call, check the Authorization header 'Bearer ' and tell me whether a credential is actually present or if it's empty.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/authorization-scheme-identify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically identify the HTTP Authorization scheme from a raw header string without sending credentials to an external service for validation. It is ideal for security-sensitive pipelines where you need zero data retention guarantees and a verifiable audit trail (SHA-256 of input, external_calls=0). Prefer it over manual regex parsing when you need a structured, schema-versioned result. It is purpose-built for AI agent workflows that handle third-party or user-supplied headers and need to branch logic based on auth type.
Side effects
- Header exceeds 8192 character limit — request rejected
- Malformed or missing header value — scheme may return as unknown or null
- Empty string input — credential_present returns false
- Unrecognized or non-standard auth scheme — scheme field may not match expected enum values
- Network or payment failure via x402 — 402 response requiring USDC payment on Base or Solana
