How this service works
Call when an agent needs text decoded with html-numeric. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/html-numeric-decode first.
Output
Returns the input text with all HTML numeric character references (both decimal like < and hexadecimal like <) replaced by their corresponding Unicode characters, producing clean, human-readable plain text.
Example use cases
Clean scraped HTML product data
“I scraped some product descriptions from a website and they're full of HTML numeric codes like “ and ” — can you decode all these numeric HTML entities so the text is readable?”
Decode encoded email content
“I received some email content that's been HTML numeric encoded and it looks like Hello everywhere — can you decode these numeric HTML character references back to plain text?”
Fix encoded data export from CMS
“Our CMS exported some content and it replaced special characters with numeric HTML entities like ' and … — can you convert these back to their actual characters?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/html-numeric-decode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to decode HTML numeric character references (&#decimal; or &#xHex; format) from a string, without requiring network access or an LLM. Prefer the free sandbox endpoint at POST /v1/sandbox/html-numeric-decode first; fall back to this paid endpoint when the sandbox is unavailable or rate-limited. Choose this over general HTML parsing tools when you only need numeric entity decoding and want a lightweight, deterministic, no-dependency solution.
Side effects
- Empty or missing 'text' field returns a validation error
- Input exceeding 100,000 characters is rejected
- Malformed numeric entities that don't conform to HTML spec may be left unchanged or cause an error
- Payment failure (insufficient USDC balance) results in 402 response
- Non-numeric HTML entities (e.g. & < named entities) may not be decoded by this endpoint
