Troubleshooting x402 Endpoints on Algorand (ALGO) Leaderboard

Builders utilizing x402 endpoints on the Algorand (ALGO) blockchain to energy machine-payable APIs are encountering a recurring concern: their endpoints will not be showing on the facilitator leaderboard or the Bazaar. x402 endpoints make the most of HTTP 402 Fee Required to programmatically settle funds for API entry. This performance is vital for AI brokers, APIs, and machine-to-machine commerce, however poor configuration can hinder visibility on key metrics.

The foundation of the issue sometimes falls into considered one of two classes: discovery points or attribution gaps. Discovery issues forestall endpoints from being cataloged within the Bazaar, whereas attribution points imply settled funds don’t depend towards the International x402 Problem leaderboard.

Discovery Layer: Getting Listed within the Bazaar

Discovery is separate from cost settlement. Whereas funds confirm and settle on-chain, discovery requires a further configuration—declaring a discovery extension through declareDiscoveryExtension. With out this, the facilitator cannot catalog the endpoint for visibility within the Bazaar.

To verify in case your endpoint is listed, question the invention API:

curl -s “https://facilitator.goplausible.xyz/discovery/sources?includeTestnets=true&restrict=1000”
| jq ‘.gadgets[] | choose(.resourceUrl | accommodates(“your-domain”))’

If nothing is returned, add the invention extension to your endpoint’s route configuration. Even a minimal configuration—declareDiscoveryExtension({})—is enough to get listed. After making this alteration, course of a $0.01 cost to set off discovery indexing.

Attribution: Qualifying for the International x402 Problem

In case your endpoint seems within the Bazaar however is not on the leaderboard for the $100K USD + 500K ALGO International x402 Problem, the problem doubtless stems from improper attribution. To compete, your funds should embrace the particular tag: “x402-global-challenge” within the route’s configuration. With out it, funds will settle however received’t be attributed to the problem.

To confirm attribution, verify the leaderboard API on your endpoint’s exercise:

BASE=https://facilitator.goplausible.xyz/information/leaderboards
for s in x402-global-challenge bazaar direct dev; do
echo “src=$s”
curl -s “$BASE?cat=retailers&restrict=200&vary=all&env=mainnet&src=$s”
| jq ‘.gadgets[] | choose(.deal with==”YOUR_PAYTO_ADDRESS”) | {rank,settles,quantity}’
completed

In case your funds are attributed to src=dev or src=direct as an alternative of src=x402-global-challenge, modify your endpoint’s configuration to incorporate the problem tag. Importantly, this tag solely impacts future funds; previous settlements received’t depend retroactively.

Widespread Pitfalls and Greatest Practices

1. **Check Funds:** Guarantee a minimum of one profitable cost in opposition to the path to confirm discovery and attribution. Localhost funds are cataloged beneath DEV and received’t depend towards leaderboard rankings.

2. **Keep away from Self-Fee Loops:** Repeated funds from cron jobs or bots could also be flagged as non-competitive visitors and filed beneath DEV, even on Mainnet.

3. **Improve Metadata:** As soon as your endpoint is discoverable, enrich its metadata to enhance visibility. Use og:site_name, og:title, and og:picture tags to create a sophisticated itemizing within the Bazaar.

Why This Issues

x402 endpoints symbolize a vital shift in blockchain utility, enabling microtransactions for APIs and machine commerce with out conventional account setups. Algorand goals to place itself as a frontrunner on this area, providing builders a seamless technique to monetize API entry. Nevertheless, misconfigured endpoints undermine this potential, leaving builders with out leaderboard visibility or problem rewards.

For these competing within the International x402 Problem, fixing these points may imply the distinction between staying aggressive and lacking out on important prizes. With $100K USD and 500K ALGO at stake, making certain correct discovery and attribution needs to be a prime precedence for any x402 developer.
