For Agents
Encode a value into a barcode image or decode an uploaded barcode image into its numeric value across many industry standard types.
Use for: Encode an order number into a Code 128 barcode, Decode an uploaded photo of a barcode, List which barcode types are supported for encoding, Generate a UPC barcode for a retail SKU
Not supported: Does not handle product-database lookups, price scraping, or QR code generation - use for barcode encoding and decoding of supported industry types only.
Fun Generators' Barcode API encodes a numeric value into a barcode image and decodes barcode images back into their numeric form. It supports many common industry-standard barcode types and exposes 4 endpoints: list of supported encode types, encode operation, list of supported decode types, and decode operation. The API is suited to back-office automations that emit barcodes for shipping labels, asset tags, or warehouse pick-lists, and to scanning workflows that lift codes off uploaded images.
Install Jentic One Beta
Connect the Barcode API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Barcode API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Ffungenerators.com%2Ffungenerators-barcode" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Ffungenerators.com%2Ffungenerators-barcode" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Barcode API.
Encode a value into a barcode image for one of many supported types
Decode an uploaded barcode image into its numeric or alphanumeric value
List the barcode types supported for encoding before generating an image
List the barcode types supported for decoding to set scanner expectations
Embed barcode images directly into shipping labels and asset tags
Lift codes off photographed barcodes inside operations workflows
Use Cases
Patterns agents use Barcode API for, with concrete tasks.
★ Shipping Label Barcode Generation
Warehouse and shipping teams need a barcode rendered onto each label. A label-rendering service calls GET /barcode/encode with the order number and barcode type and embeds the returned image into the printed label. Listing supported types via GET /barcode/encode/types lets the integration validate user-selected formats up front.
Call GET /barcode/encode for value 'ORD-12345' with type code128 and embed the resulting image in a shipping label
Inventory Scan Decode
Operations teams uploading photographed barcodes from a warehouse-floor app POST the image to /barcode/decode and receive the numeric or alphanumeric value back. This decouples the mobile app from any embedded scanning library and keeps a server-side audit trail of every scan.
POST /barcode/decode with a base64 image of a UPC barcode and return the decoded numeric value
Capability Discovery
Before exposing a barcode-type picker to end users, a UI calls GET /barcode/encode/types and GET /barcode/decode/types so the dropdown only shows formats the API actually supports. This avoids runtime failures when a user picks an unsupported encoding.
Call GET /barcode/encode/types and render only the listed types in the user-facing barcode picker
Agent-Driven Label Workflow
An AI agent fields prompts like 'generate a barcode for SKU ABC-001' and chooses an appropriate type, encodes the value, and returns a base64 image. Through Jentic the bearer token stays vaulted and the agent only sees scoped operation results, so the same agent can serve many tenants safely.
Search Jentic for 'encode a barcode', load GET /barcode/encode, execute with value 'SKU-ABC-001' and type code128

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Fungenerators Barcode API by hand means passing your API key as a bearer token in the Authorization header, choosing the http or https api.fungenerators.com host, and reading the supported encode and decode types yourself. Through Jentic you install once, import the Barcode API from the API Directory, store the token once, and your agent calls it.
Permission scoping
The Barcode API takes its input in query and body parameters rather than a resource path, so you limit the agent to the operations it needs, such as encoding a barcode or decoding one. You choose which operations it may call, and nothing outside that set runs.
Credential isolation
Your Fungenerators token is stored once, encrypted, by your own Jentic One instance and injected into the Authorization header at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'encode a barcode' or 'decode a barcode', and Jentic returns the matching GET /barcode/encode or POST /barcode/decode operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Barcode API through Jentic.
What authentication does the Fun Generators Barcode API use?
The Barcode API uses bearer-token authentication. The token is issued on the Fun Generators subscription page. Through Jentic the bearer token is stored encrypted in your Jentic One instance and injected into the Authorization header at execution time.
Which barcode types can I encode with the Barcode API?
Call GET /barcode/encode/types to retrieve the live list of supported encoding formats. The API documents support for many industry-standard formats including Code 128, EAN, and UPC variants; the types endpoint is the authoritative source.
Can I decode an uploaded image of a barcode?
Yes. POST /barcode/decode with the image payload and the API returns the decoded value. Use GET /barcode/decode/types first to confirm the format you expect to scan is supported by the decoder.
What are the rate limits for the Fun Generators Barcode API?
Fun Generators applies per-subscription quotas rather than a documented per-second rate limit. Pace bulk encoding jobs and back off on any 429 responses; cache encoded images by value+type to avoid recomputing identical barcodes.
How do I generate a barcode through Jentic?
Search Jentic for 'encode a barcode', load the GET /barcode/encode schema, and execute with value and type query parameters. The response includes the generated barcode image data.
Is the Barcode API free?
Fun Generators runs a paid subscription model for its API family. Sign-up details and tier pricing are at http://fungenerators.com/api/barcode/. Plan integrations against a paid tier rather than a free trial for production usage.
Can I limit what my agent is allowed to do with the Barcode API?
Yes. Because Jentic One is self-hosted, you set the rules that decide which operations and credentials your agent may use. The Barcode API takes its input in query and body parameters rather than a resource path, so you can restrict the agent to only the operations it needs, such as encoding a value with GET /barcode/encode or decoding an image with POST /barcode/decode. You choose which of these operations it may call, and nothing outside that set runs.
