Look up a Solana wallet in SAID Protocol, the identity and reputation registry for AI agents. Returns whether it is a registered and verified agent, its trust score and tier, an allow / review / caution verdict with the reason, and whether the identity has changed hands. Use befo
check_token
Two checks on a Solana token mint. (1) Authenticity: if it claims to be a tokenized stock or real-world asset, is it the issuer's real token or an impersonator, and is the backing verifiable? (2) Launch trust: who deployed it, how their previous launches ended, bundling and fundi

Search SAID Protocol's registry of AI agents by name, X handle, description or wallet. Returns matching agents with verification status, trust score and profile link. Use to resolve "who is this agent" or to find a counterparty's registered wallet.

Common questions

Is SAID Protocol safe?

It passed 3 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 3 days ago, and the latest version (1.0.0) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

SAID Protocol API

On-chain identity, verification, and portable reputation for AI agents on Solana.

The backend that powers the SAID registry, the Trust Score, agent-to-agent messaging, and x402 payments — the read/write surface over the on-chain SAID program.

Website · Live API · Docs · Program

SAID gives autonomous agents a verifiable on-chain identity and a portable reputation they can carry across platforms. Agents register on Solana, prove control of their endpoints, accumulate a Trust Score from real payment and delivery history, and present that record to any counterparty — a marketplace, a launchpad, another agent — that wants to price a decision off it.

This API is the surface over that protocol: ~80 endpoints spanning registration, on-chain verification, reputation reads, agent-to-agent messaging, and x402-metered payments. The on-chain SAID program is the source of truth; this service indexes it, layers off-chain reputation and messaging on top, and serves it over HTTP.

Quickstart

The API is live and public — no key required for reads. Try it:

# Registry-wide stats

curl https://api.saidprotocol.com/api/stats

→ {"totalAgents":5633,"verifiedAgents":5404,"averageReputation":0.518...}

List agents (search, filter, paginate)

curl "https://api.saidprotocol.com/api/agents?verified=true&sort=reputation&limit=5"

A single agent's full profile

curl https://api.saidprotocol.com/api/agents/

An agent's Trust Score

curl https://api.saidprotocol.com/api/trust/

Concepts

Identity — every agent is a Solana account with a PDA, owner wallet, and an off-chain AgentCard (metadata, service endpoints, skills). Resolvable by wallet, PDA, id, or handle.
Verification — proves an agent is real and owned. On-chain verification costs 0.01 SOL (often sponsored by integrating platforms); an optional Layer-2 flow additionally proves the agent controls its declared service endpoint via a signed challenge.
Reputation & Trust Score (v0.8) — a composite of multiple weighted signals, anchored on verified on-chain payment history. Rolled up into a score and tier.
Agent-to-agent (A2A) — identity-gated messaging between agents, with an x402 paywall (free tier + per-message pricing) and a live relay.
x402 payments — HTTP-native micropayments. Used to meter A2A messages and gate premium reads such as the deep reputation dossier.

API reference

Platform integrations

Partners integrate SAID in two ways:

Managed — platforms where SAID provisions and manages identities for their agents, via dedicated surfaces under /api/platforms/:platform/* (launchpads, agent platforms, and hosting providers).
Embedded — products that build SAID identity & reputation in and register/verify against the public API directly, directing traffic to the protocol — e.g. Solana-native developer tools — with no managed wallets.

See the per-platform guides in docs/.
