Other ways to use Truth Table Generator
Same data, same APIVerve account, same credit balance — one key works on all of them.
Give it to an AI agentConnect over MCP and your agent calls it as a native tool — Claude, Cursor, ChatGPT.on VerveKit Google Sheets or ExcelA =VERVE() formula fills a column — no script, no export, recalculates in place.on VerveSheets Ground an agent on itA cited, machine-checkable fact your model can't produce on its own.on VerveContext
What does the Truth Table Generator API do?
Truth Table Generator creates complete truth tables for boolean expressions with support for AND, OR, NOT, XOR, NAND, and NOR operators.
How do I authenticate Truth Table Generator API requests?
Pass your API key in the x-api-key header over HTTPS. One key works across all 300+ APIVerve APIs — there are no per-endpoint credentials.
How much does the Truth Table Generator API cost?
Each call spends 2 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.
How fast is the Truth Table Generator API?
Response time depends on the endpoint — the p50 through p99 latency for this API is published on this page. Requests are served over HTTPS through a global edge network.
What response formats does the Truth Table Generator API support?
JSON by default, plus XML and YAML via the format parameter. GraphQL and an MCP interface for AI agents are available across the catalog.
What HTTP method does the Truth Table Generator API use?
GET over HTTPS, following standard REST conventions with a consistent { status, error, data } response envelope.
Request parameters — GET /v1/truthtable
Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.
Required
| Parameter | Type | Example | Description |
|---|---|---|---|
expressionRequired | string | A AND B OR C | Boolean expression using A-Z variables and operators (AND, OR, NOT, XOR, NAND, NOR) |
curl "https://api.apiverve.com/v1/truthtable?expression=A%20AND%20B%20OR%20C" \
-H "x-api-key: YOUR_API_KEY"Authentication
Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.
| Header | When | Value |
|---|---|---|
x-api-keyRequired | Every request | Your API key. Header names are case-insensitive, so X-API-Key is the same header. |
AuthorizationAlternate | Instead of the above | Bearer <key> — for clients that only expose bearer auth. Resolves to the same account and the same billing. |
401 is the only auth verdict
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Response — GET /v1/truthtable
Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

expression | string | "A AND B OR C" | Original boolean expression input by user |
normalizedPremium | string | "A && B || C" | Expression normalized with standard operators like && and || |
variablesPremium | array | [A, ...] | Array of unique variable names found in expression |
variableCountPremium | number | 7 | Total count of unique variables in boolean expression |
rowCountPremium | number | 128 | Number of rows in truth table (2^variableCount) |
rows | array[128] | Array of truth table rows with inputs and result values | |
inputs | object | {...} | Input variable values for current truth table row |
A | number | 0 | |

Response headers
Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.
| Header | What it carries |
|---|---|
x-api-remaining-credits | Credits left in the current cycle |
x-api-credits-used | Credits spent in the current cycle |
x-api-max-credits | The allowance for the cycle |
x-api-version | Version of the endpoint that answered |
Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter that has to change. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted here | A key restriction or an IP allow-list — never a bad key. |
429 | Rate limited, or out of credits | Read error to tell them apart, then back off or top up. |
What a call costs — 2 credits per call
Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.
| Plan | Per month | Credits | Truth Table Generator calls | Per 1,000 calls |
|---|---|---|---|---|
| Free | Free | 200 | 100 | Free |
| Starter | $29.99 | 200,000 | 100,000 | $0.30 |
| Pro | $99.99 | 1,000,000 | 500,000 | $0.20 |
| Mega | $299.99 | 4,000,000 | 2,000,000 | $0.15 |
Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Changelog — Truth Table Generator API
Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
Nothing recorded yet
Entries are picked up from dated catalog snapshots, so the first one appears after the next snapshot that moves something. A period where nothing changed produces no entry — silence is a valid changelog for the Truth Table Generator API.
