How this service works
Find the best x402 API for a task. Describe what you need (for example "remove the background from a photo") and get the matching sellers from the CDP Bazaar ranked by relevance, how many distinct buyers paid them in 30 days, their uptime measured by our monitor every 6 hours, and price. Each result has its price, payers, uptime, median latency and how to call it (method and example input).
Output
A JSON object containing the original task string, a ranked list of matching x402 API sellers (each with resource URL, relevance score, description, price in USD, 30-day payer count, 30-day call count, uptime percentage, median latency in ms, and example call instructions), a human-readable explanation of the scoring formula, a breakdown of excluded listings by reason, and the total number of Bazaar listings considered.
Example use cases
Find cheapest image background remover
“Search the x402 Bazaar for APIs that remove backgrounds from images and return only sellers charging under $0.003 per call — show me the top 3 ranked by relevance and uptime.”
Discover reliable audio transcription APIs
“Find me x402 APIs for transcribing audio files — I want sellers that have had at least 10 distinct payers in the last 30 days so I know they're actually being used.”
Compare PDF-to-text conversion services
“I need to convert PDFs to plain text — search the x402 Bazaar for APIs that do this and show me the top 5 results including their price, median latency, and how to call each one.”
Technical details
Endpoint
GEThttps://tvy64m9w0dfvxmkq.68r.lambda-web.us-east-1.on.aws/v1/find?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and select the best x402-compatible API for a specific task at runtime, especially when comparing multiple sellers by trustworthiness signals (payer count, uptime) and cost. Prefer this over hardcoding a specific x402 seller URL when the optimal provider may change over time or when you want to filter by price ceiling or minimum adoption threshold.
Side effects
- No matching sellers found for the task description — results array is empty
- task parameter missing — request fails with validation error
- max_price_usd or min_payers filters too restrictive — all candidates excluded
- Payment not included or incorrect — 402 Payment Required response returned
- Lambda cold start may add latency on first call
- Uptime data unavailable for new sellers — uptime_30d returned as null
