JSON Number Coerce
x402
JSON Number Coerce is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-16).
Coerces an array of string values into numeric types, reporting normalized values and rejected entries with counts in a versioned deterministic result contract.

How this service works
JSON Number Coerce: JSON Number Coerce coerces explicit numeric strings while reporting rejected values from bounded caller-supplied values without an external provider. Call JSON Number Coerce before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Number Coerce as versioned deterministic JSON. Price: $0.001 USDC via x402…
Output
A versioned deterministic JSON object containing normalized numeric values for successfully coerced inputs, a list of rejected values that could not be parsed, counts of accepted and rejected entries, and a versioned result contract identifier.
Example use cases
Pre-flight data cleaning for strict tool
“Before I send this batch of price strings to the trading engine, coerce them all to numbers and flag any that can't be parsed — the values are ['100.5', '200', 'N/A', '350.00', 'pending', '99.9'].”
Agent output validation before downstream handoff
“My agent just produced a list of quantity strings from a user's order form: ['1', '2', 'two', '10', '', '5']. Can you coerce them into numbers and give me a count of how many were valid vs rejected?”
Cleaning scraped numeric data
“I scraped these values from a webpage and they're all strings: ['$42.00', '3.14', 'n/a', '0', '1,200', '88.5']. Try to coerce them to proper numbers and tell me which ones failed.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-number-coerce?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or pipeline needs to convert a batch of caller-supplied string values into proper numeric types before handing them to a downstream tool with a strict JSON schema. It is especially useful when the source data is untrustworthy or mixed (e.g. scraped, user-entered, or agent-generated), and you need explicit counts of valid vs rejected values plus a normalized output list — all in a versioned, deterministic contract suitable for audit or retry logic.
Side effects
- Empty values array returns zero counts with no normalized values
- All values are non-numeric strings — result contains full rejection list and zero normalized values
- Array exceeds 256-item limit — request rejected with validation error
- Individual string exceeds 8192 character limit — offending item rejected or request fails
- Malformed request body — HTTP 4xx error returned
