Copy this into Claude Code, Cursor, Codex, Aider or Cline. It carries the endpoint,
the full schema, a sample response, and the credit rules — so the agent wires
ascii-table-reference up correctly without draining your key.
POST /v1/tools/ascii-table-reference/dry-run, which validates
the request and returns the response shape for
0 credits. Only the final confirmation call is billed
(1 credit).
/tools/ascii-table-reference/prompt.md
(?variant=cursor / ?variant=mcp).
Integrate the MiniWebtool ASCII Table Reference API into this project.
## Your task
1. Read the reference below.
2. Ask me where this belongs in the codebase if it is not obvious.
3. Write the integration in the language and style of the surrounding code:
a small typed client function, errors handled, key read from the
environment (never hard-coded, never committed).
4. Verify with `/dry-run` first, then exactly one live call.
5. Show me the diff and the live result.
## Credit budget — follow these exactly
This API is metered. A live call costs 1 credit; the free tier
includes 1,000 credits per month. Burning them during integration is the
single most common way to waste this key.
1. **Do all wiring against `/dry-run`, which costs 0 credits.** It validates the
payload for real and returns a sample result with the exact response shape.
Iterate there until your request builds and your parsing works.
2. **Make at most ONE live `/run` call** — a single end-to-end confirmation once
dry-run passes. Print the result, then stop.
3. **Never call the API from unit tests, examples, or a retry loop.** Assert
against the sample response captured from `/dry-run` instead.
4. **On 4xx, fix the payload — do not retry.** The error body is RFC 7807
`application/problem+json` and says exactly what is wrong.
5. **On 429, honour `Retry-After`** and back off; do not tighten the loop.
6. **Read `X-MWT-Credits-Remaining`** on every response. If it drops below 50,
stop making live calls and tell me.
7. If the integration needs repeated calls at runtime, **cache by input** — this
tool is deterministic, so the same input always returns the same output.
## The API
**ASCII Table Reference** — Full 7-bit ASCII table in decimal, hex, octal, and binary, with single-character lookup.
- Live endpoint: `POST https://api.miniwebtool.com/v1/tools/ascii-table-reference/run` — costs 1 credit
- Dry run: `POST https://api.miniwebtool.com/v1/tools/ascii-table-reference/dry-run` — costs 0 credits, same auth and validation
- Auth: `Authorization: Bearer <MINIWEBTOOL_API_KEY>`
- Content type: `application/json`
- Tool version: `2026-04-22` (output shape is stable within a major version)
- Full machine-readable spec: `https://api.miniwebtool.com/v1/openapi.json`

`result` holds the tool output. Errors come back as
`application/problem+json` with `type`, `title`, `status`, and `detail`.
### Getting a key
If `MINIWEBTOOL_API_KEY` is not already in the environment, stop and ask me for
one — do not sign up, scrape, or guess a key. Free keys: https://api.miniwebtool.com/dashboard/
Integrate the MiniWebtool ASCII Table Reference API into this project.
## Your task
1. Read the reference below.
2. Ask me where this belongs in the codebase if it is not obvious.
3. Write the integration in the language and style of the surrounding code:
a small typed client function, errors handled, key read from the
environment (never hard-coded, never committed).
4. Verify with `/dry-run` first, then exactly one live call.
5. Show me the diff and the live result.
## Credit budget — follow these exactly
This API is metered. A live call costs 1 credit; the free tier
includes 1,000 credits per month. Burning them during integration is the
single most common way to waste this key.
1. **Do all wiring against `/dry-run`, which costs 0 credits.** It validates the
payload for real and returns a sample result with the exact response shape.
Iterate there until your request builds and your parsing works.
2. **Make at most ONE live `/run` call** — a single end-to-end confirmation once
dry-run passes. Print the result, then stop.
3. **Never call the API from unit tests, examples, or a retry loop.** Assert
against the sample response captured from `/dry-run` instead.
4. **On 4xx, fix the payload — do not retry.** The error body is RFC 7807
`application/problem+json` and says exactly what is wrong.
5. **On 429, honour `Retry-After`** and back off; do not tighten the loop.
6. **Read `X-MWT-Credits-Remaining`** on every response. If it drops below 50,
stop making live calls and tell me.
7. If the integration needs repeated calls at runtime, **cache by input** — this
tool is deterministic, so the same input always returns the same output.
## The API
**ASCII Table Reference** — Full 7-bit ASCII table in decimal, hex, octal, and binary, with single-character lookup.
- Live endpoint: `POST https://api.miniwebtool.com/v1/tools/ascii-table-reference/run` — costs 1 credit
- Dry run: `POST https://api.miniwebtool.com/v1/tools/ascii-table-reference/dry-run` — costs 0 credits, same auth and validation
- Auth: `Authorization: Bearer <MINIWEBTOOL_API_KEY>`
- Content type: `application/json`
- Tool version: `2026-04-22` (output shape is stable within a major version)
- Full machine-readable spec: `https://api.miniwebtool.com/v1/openapi.json`
### Request body

`result` holds the tool output. Errors come back as
`application/problem+json` with `type`, `title`, `status`, and `detail`.
### Getting a key
If `MINIWEBTOOL_API_KEY` is not already in the environment, stop and ask me for
one — do not sign up, scrape, or guess a key. Free keys: https://api.miniwebtool.com/dashboard/
## Credit budget — follow these exactly
This API is metered. A live call costs 1 credit; the free tier
includes 1,000 credits per month. Burning them during integration is the
single most common way to waste this key.
1. **Do all wiring against `/dry-run`, which costs 0 credits.** It validates the
payload for real and returns a sample result with the exact response shape.
Iterate there until your request builds and your parsing works.
2. **Make at most ONE live `/run` call** — a single end-to-end confirmation once
dry-run passes. Print the result, then stop.
3. **Never call the API from unit tests, examples, or a retry loop.** Assert
against the sample response captured from `/dry-run` instead.
4. **On 4xx, fix the payload — do not retry.** The error body is RFC 7807
`application/problem+json` and says exactly what is wrong.
5. **On 429, honour `Retry-After`** and back off; do not tighten the loop.
6. **Read `X-MWT-Credits-Remaining`** on every response. If it drops below 50,
stop making live calls and tell me.
7. If the integration needs repeated calls at runtime, **cache by input** — this
tool is deterministic, so the same input always returns the same output.
Add the MiniWebtool MCP server to this project, then use the
`ascii-table-reference` tool from it.
Server URL: https://api.miniwebtool.com/v1/mcp
Transport: HTTP (Streamable HTTP / JSON-RPC 2.0)
Auth header: `Authorization: Bearer <MINIWEBTOOL_API_KEY>`
Claude Code:
```bash
claude mcp add --transport http miniwebtool https://api.miniwebtool.com/v1/mcp \
--header "Authorization: Bearer $MINIWEBTOOL_API_KEY"
```
Or add it to the MCP config file your client uses:
```json
{
"mcpServers": {
"miniwebtool": {
"type": "http",
"url": "https://api.miniwebtool.com/v1/mcp",
"headers": { "Authorization": "Bearer ${MINIWEBTOOL_API_KEY}" }
}
}
}
```
Once connected, `tools/list` exposes `ascii-table-reference` with its JSON Schema, so you can
call it directly instead of writing an HTTP client.

Authorization: Bearer <key> and Content-Type: application/json. Copy-paste snippets in 7 languages are under Code examples.
{request_id, tool, tool_version, credits_used, result}. The typed output lives in result.
Full 7-bit ASCII table in decimal, hex, octal, and binary, with single-character lookup. Use it to add this utility without rebuilding formulas, validation, examples, and documentation.
1 credit per successful call. Failed calls (validation errors, 5xx) don't bill.
Required fields: (none). Full schema at /v1/openapi.json.
Yes — same input, same output, forever. Tool version 2026-04-22; output shape is stable within a major version.
Yes. Connect to https://api.miniwebtool.com/v1/mcp over the Model Context Protocol. The agent discovers `ascii-table-reference` with its JSON Schema automatically, so the model can plan while MiniWebtool handles the exact tool result.
JSON with a stable envelope: `{request_id, tool, tool_version, credits_used, result}`. Errors are RFC 7807 `application/problem+json`.
Every endpoint on this site is also exposed via the
Model Context Protocol at
https://api.miniwebtool.com/v1/mcp.
Claude, Cursor, and any MCP-capable agent can discover this tool
(ascii-table-reference)
and its JSON Schema automatically — no client codegen.
