How this service works
Deterministic $0.25 readiness check for /api/grant/loi ($2.00): scores completeness of your funder/project/org/amount/duration inputs against the six-part LOI structure the full product commits to, flags exactly which sections will need [BRACKETED] placeholders, and guesses funder-type register from the name alone. No live funder research, no letter text, no LLM call — pure input grading before you spend $2 on the real draft.
Output
Returns a completeness score for the LOI inputs across the six-part LOI structure, a list of which sections will require bracketed placeholders in the full draft, and an inferred funder-type register derived from the funder name alone — all without making any LLM calls or live funder lookups.
Example use cases
Pre-draft LOI completeness check
“Before I pay for the full letter of inquiry, can you check if my inputs are ready — funder is the Robert Wood Johnson Foundation, project is an 18-month community health worker training program, org is Healthy Futures Inc, and we're asking for $75,000?”
Identifying missing LOI sections
“Can you score my LOI readiness and tell me exactly which sections will end up with bracketed placeholders? Funder is Wellcome Trust, project is a one-year infectious disease research initiative, org is BioReach Global, requesting $200,000.”
Guessing funder type before drafting
“I want to know what funder type GrantPulse will infer from the name 'Knight Foundation' and how complete my inputs are — project is a three-year arts access program, org is CultureBridge, and we need $50,000.”
Technical details
Endpoint
GEThttps://grantpulse.theaslangroupllc.com/api/grant/loi-readiness?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to validate and grade your LOI inputs before committing $2.00 to the full LOI draft generation. It is the right choice when you suspect your inputs may be incomplete, want to know which sections will have placeholders, or need a cheap pre-flight check to avoid wasting money on a draft that will be full of gaps. Prefer this over the full LOI endpoint whenever the user's inputs seem thin or uncertain.
Side effects
- Missing required inputs (funder name, project, org, amount, or duration) may result in low scores or incomplete analysis
- Funder-type inference is name-based only and may be inaccurate for obscure or ambiguous funder names
- Endpoint does not perform live funder research so the readiness score reflects input structure only, not actual funder fit
- Returns no letter text — agents expecting a draft LOI must use the /api/grant/loi endpoint instead
