Delx Handoff Size Estimate
x402
Delx Handoff Size Estimate is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Estimates the byte size and token count of a UTF-8 text string to help agents plan payload sizing before handoff operations.

How this service works
Estimate bytes/tokens for a handoff capsule string. Call when Protocol-adjacent sizing before free handoff storage. Returns bytes and token_estimate as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the exact byte count of the input text, an estimated token count, and a schema identifier string (e.g. 'delx/util-handoff-size-estimate/v1') confirming the response format.
Example use cases
Pre-flight payload size check
“I need to check if this article excerpt will fit under my 512-token API limit before I POST it — can you estimate the byte size and token count for this text: 'The global semiconductor shortage has continued to affect manufacturing output across consumer electronics, automotive, and industrial sectors throughout the year.'”
Agent handoff planning before batch
“Before I split this report into chunks and hand it off to downstream agents, can you tell me the byte and token size of this section: 'Revenue grew 18% year-over-year driven primarily by cloud services and subscription renewals in North America and EMEA regions.'”
LLM context window planning
“I'm about to inject this system prompt into an LLM call and want to know how many tokens it'll consume — can you size this text for me: 'You are a helpful assistant specialized in financial analysis. Always cite your sources, avoid speculation, and format your responses with clear headers and bullet points.'”

Endpoint
POSThttps://api.delx.ai/api/v1/x402/handoff-size-estimateWhen to prefer
Choose this endpoint when you need a quick, cheap computation of text payload size in bytes and estimated tokens before making downstream API calls, chunking decisions, or agent handoffs — especially when working within strict token budgets or payload size ceilings. It is purpose-built for agent orchestration workflows and costs only $0.001 USDC per call.
Side effects
- Missing or empty 'text' field returns a validation error
- Extremely large text payloads may be rejected or time out
- Non-UTF-8 encoded content may produce inaccurate byte counts
- Network errors or service unavailability return a 5xx response
