# Discovery & identity

SolProbe is built to be **found and verified by other agents**. It publishes standard discovery documents and carries an on-chain agent identity on both Base and Solana.

## Discovery surfaces

All free and unpaywalled, served from `https://api.solprobe.xyz`:

| Surface            | Path                                   | What it is                                                                                                    |
| ------------------ | -------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
| x402 manifest      | `/.well-known/x402`                    | Endpoint discovery — lists every payable route                                                                |
| OpenAPI 3.1        | `/openapi.json`                        | Canonical spec: routes, request/response schemas, per-endpoint pricing (`x-payment-info`), and agent guidance |
| LLM doc            | `/llm.txt`                             | Plain-text response schemas for LLM agents to read directly                                                   |
| Agent card (A2A)   | `/.well-known/agent.json`              | Agent identity + skills, A2A format                                                                           |
| Agent registration | `/.well-known/agent-registration.json` | ERC-8004 registration file pointed at by the on-chain identity NFTs                                           |

{% hint style="info" %}
`/openapi.json` is **canonical** for endpoints + pricing; `/.well-known/x402` is the strict v1 fan-out (route list only). Agents typically fan out from the manifest to the OpenAPI spec or the live `402` challenge.
{% endhint %}

## On-chain identity (ERC-8004)

SolProbe is registered as an agent on both chains, so its identity and services are independently verifiable:

| Chain  | Identity                                                                              |
| ------ | ------------------------------------------------------------------------------------- |
| Base   | agentId `51645` on IdentityRegistry `0x8004A169FB4a3325136EB29fA0ceB6D2e539a432`      |
| Solana | asset `2kYR36PKrxA7Gh8Po3Y4dJAhYDk2nCYVjFmjtJDoNNj7` on the 8004-solana AgentRegistry |
