How this service works
Grade a text against a form — meter, rhyme, line and content gates, the dictionary named; a signed record. GET ?text=&form=
Output
Returns a structured diagnostic report indicating whether the submitted text conforms to the specified poetic form, including pass/fail results and line-by-line details on meter (stress patterns, syllable counts), rhyme scheme adherence, and line count correctness.
Example use cases
Validate a student's haiku submission
“Check this haiku against the correct 5-7-5 syllable form and tell me if it passes: 'An old silent pond / A frog jumps into the pond / Splash! Silence again.' — use the haiku form.”
Debug rhyme scheme in a limerick
“My limerick doesn't feel right — can you score it against the limerick form and show me exactly which lines break the AABBA rhyme scheme? Here it is: 'There once was a man from Nantucket / Who kept all his cash in a bucket / His daughter named Nan / Ran away with a man / And as for the bucket, Nantucket.'”
Meter check for a sonnet draft
“I wrote a Shakespearean sonnet but I'm not sure the iambic pentameter is consistent — run it through the sonnet form scorer and highlight any lines with meter problems: 'When forty winters shall besiege thy brow / And dig deep trenches in thy beauty's field...'”
Technical details
Endpoint
GEThttps://api.s2ar.dev/x402/v1/score?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, rule-based evaluation of poetic structure rather than subjective AI feedback. It is ideal for grading assignments, linting poetry generators, enforcing form constraints in creative writing tools, or building feedback loops that require reproducible pass/fail results on meter, rhyme, and line structure.
Side effects
- Missing 'text' parameter returns a 400-level error
- Unknown or unsupported form name returns an error or empty result — caller should first fetch /v1/score/forms to list valid form names
- Very long texts may exceed processing limits
- Non-English text may produce inaccurate meter analysis if the form is language-specific
