POST /api/token-generate1 quota unit per call · cache hits free

Generate cryptographically random tokens for session IDs, CSRF tokens, API keys, magic-link tokens. Configurable length and encoding (hex, base64url, base64).

Generates a cryptographically random token of the requested length and encoding. Use this for session IDs, CSRF tokens, invitation links, password-reset tokens, API keys — anything that needs to be unguessable. Options: - `bytes` (default 32): how many random bytes to generate. The resulting token string will be longer because the encoding expands. - `encoding`: `hex` (2× expansion), `base64url` (default, ~1.33× expansion, URL-safe), or `base64` (same expansion, uses `+/`). Returns the encoded token plus its bit-strength (8 × bytes).

Inputs

NameTypeDefaultDescription
lengthnumber (1…4096)32Token length, in characters of the chosen alphabet.

Response

Modes: json. Cache: not cacheable.

Every response carries x-cache (HIT / MISS / BYPASS), x-cache-signature (stable across identical inputs), and the rate-limit headers listed below.

Quota & limits

Cost per call1 unit against the 10,000-unit monthly quota. Cache hits are free — only cache misses decrement.
Burst limit200 requests per rolling minute, shared across all tools.
Max request size1 KiB (base64 inflates file payloads ~33% — the limit applies to the decoded bytes).
Max response size8 MiB
Timeout5s wall clock.
Rate-limit headersX-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Burst-Limit on every response; X-Quota-Warning once 80% of the monthly quota is spent; Retry-After on 429s.

Errors

Errors are JSON with an error string; schema failures add a details object (Zod's flattened field errors).

StatusWhenBody
400Input fails the tool's schema (wrong type, missing required field, malformed base64) or the file bytes can't be parsed as the expected format.{ "error": "invalid inputs", "details": { "fieldErrors": { … } } }
401Missing or invalid X-Api-Key / X-Account-Id headers (or no session when called from the browser).{ "error": "unauthorized" }
404Unknown tool id, or calling /api/* on the website hostname instead of api.xtract.bot.{ "error": "not found" }
413Request body over the tool's max request size, or an image header declaring more megapixels than the tool's pixel budget.{ "error": "…exceeds maxRequestBytes…" }
415Content-Type isn't application/json on the json-body transport.{ "error": "unsupported content-type; expected application/json" }
429Monthly quota or the 200/min burst limit exhausted. Check Retry-After and the X-RateLimit-* headers.{ "error": "monthly quota exceeded", "monthRemaining": 0, … }
5xxConversion engine failure. Safe to retry; if it persists, the input is hitting a bug — please report it.{ "error": "…" }
