x402
Delx Commerce — Agent Delivery Quality Score is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Computes a weighted composite quality score for agent-delivered data, combining latency, validity, freshness, and completeness metrics into a single verifiable score.

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing a composite quality score (0–1), per-metric scores for latency, validity, freshness, and completeness, the sum of weights used, a transparency flag, an SHA-256 hash of the input for auditability, the number of external calls made (always 0), and a retained flag (always false). The status field indicates pass/fail against the scoring operation.
Example use cases
SLA compliance check for agent fleet
“I need to verify that our agent delivery met quality standards — latency was 0.75, validity 1.0, freshness 0.85, completeness 0.9. Weight validity and completeness at 0.4 each and the others at 0.1. What's the composite quality score?”
Benchmark agent output before publishing
“Before we publish this agent's result, score its delivery quality: latency 0.6, validity 0.95, freshness 1.0, completeness 0.8, with equal weights on all four metrics.”
Compare delivery runs in a pipeline
“Give me a delivery quality score for this run — latency 0.5, validity 0.9, freshness 0.7, completeness 1.0 — I want to track whether this run was better than last time using balanced weights.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-delivery-quality-score?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a transparent, auditable, pay-per-use composite quality score for agent deliveries — especially when you want a verifiable SHA-256 input hash and no data retention, suitable for on-chain or contractual SLA verification. Prefer it over building your own weighted scoring logic when you need a standardized, tamper-evident score with a defined schema (delx/util-agent-delivery-quality-score/v1) that can be referenced in delivery contracts.
Side effects
- Missing or invalid numeric metric values may cause computation errors or unexpected scores
- Weights that don't sum to 1 may produce non-normalized composite scores
- Sending more than 128 weight properties will exceed the maxProperties limit and may be rejected
- Malformed JSON body results in a 400-level error
- Payment failure (insufficient USDC balance or invalid x402 payment) blocks the request entirely
