# did-web-resolve

> did-web-resolve 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).

Resolves a did:web DID identifier or domain to its DID document, returning verification methods, authentication references, services, and document validity.

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 did-web-resolve-f3220633
```

Example prompt: Can you resolve the did:web DID for example.com and tell me its verification methods, controller, and whether the document ID matches the DID?

## When to prefer this

Choose this endpoint when you need to resolve did:web identifiers specifically (not did:key, did:ion, or other DID methods), particularly for agent-to-agent trust checks, verifying a domain's decentralized identity, or extracting cryptographic keys and services from a DID document without running your own resolver infrastructure.

## Known failure modes

- DID or domain has no /.well-known/did.json or /path/did.json — returns not found error
- Malformed did:web identifier — input validation error
- DID document is unreachable due to network/DNS issues — fetch failure
- DID document id does not match the resolved DID — flagged as mismatch in response
- Invalid JSON in the remote DID document — parse error

## How this service works

did:web resolver: converts a did:web identifier (or domain) to its DID document URL (/.well-known/did.json or /path/did.json), fetches it and returns the id, controller, verification methods (id, type, public key kind), authentication/assertion references, services, and whether the document id matches the DID. Decentralised-identity checks for agent-to-agent trust. $0.01 per DID.

## Output

Returns the DID document's id, controller, an array of verification methods (each with id, type, and public key), references for authentication and assertion, listed services, and a boolean indicating whether the document's id field matches the resolved DID.
