revert.wtf Agent API Skill

Use revert.wtf safely from agents, tools, browsers, or integrations through bounded HTTP APIs, MCP tools, and lightweight package subpaths without downloading the full catalog into client bundles.

Use this skill when an agent needs to explain an EVM/RPC/provider/wallet/AA/x402 error, resolve a selector, search the catalog, or integrate revert.wtf into a product.

Default Choice

• Prefer MCP when the agent runtime supports MCP.
• Prefer the website HTTP API when calling the hosted service from an agent or app backend.
• Prefer package subpaths for local code.
• Never import the full catalog-backed parser into browser/client bundles for one-off searches.

MCP Tools

Use bounded tools:

• explain_error for raw errors, traces, JSON strings, revert bytes, and x402 payloads.
• search_catalog for catalog discovery. It returns summaries with limit, offset, totalMatches, and hasMore.
• get_error only after search_catalog returns a specific id.
• lookup_selector for 4-byte selectors.
• decode_revert_data for raw revert bytes.
• explain_aa_error for AAxx and EntryPoint failures.
• search_blockscout_chains and get_blockscout_chain for Blockscout registry checks.

Do not request or construct an all-catalog dump. Page through summaries only when the user explicitly needs breadth.

Hosted HTTP API

POST JSON to the public web API from a server/agent context:

curl -s https://revert.wtf/api/explain \
  -H "content-type: application/json" \
  -d '{"raw":"{\"code\":-32000,\"message\":\"nonce too low\"}"}'

Useful endpoints:

• POST /api/explain with { "raw": "..." }
• POST /api/revert-decode with { "data": "0x...", "abiText": "[...]" }
• POST /api/aa-decode with { "raw": "AA23 reverted or OOG" }
• POST /api/selector with { "selector": "0x08c379a0" }
• POST /api/search with { "query": "AA23", "limit": 20, "offset": 0 }

Inputs are capped for parsing. Do not paste private keys, seed phrases, access tokens, unreleased exploit details, or personal data.

Use /api/search for discovery and /api/explain for a specific raw failure. Search returns summaries; fetch or explain the selected item instead of asking for broad payloads.

Package Imports

Use precise subpaths:

import { explain } from "@revertwtf/parser/explain"; // server/API path
import { decodeRevertData } from "@revertwtf/parser/decode";
import { describePanic } from "@revertwtf/catalog/panic";
import { listKnownAACodes } from "@revertwtf/aa/parse";
import { searchCatalog } from "@revertwtf/search"; // server-side SQLite FTS

Browser/client bundles should use small helpers or call an API route. Full-data surfaces such as @revertwtf/catalog, @revertwtf/parser/explain, and @revertwtf/aa/explain belong on a server/API boundary.

For browser apps, prefer the lightweight SDK:

import { createRevertClient } from "@revertwtf/client";

const revert = createRevertClient();
const result = await revert.searchCatalog({ query: "x402 payment required", limit: 5 });
