Mix the yeast and the warm water in a large bowl and let sit for 10 minutes. Stir in the agave syrup, salt and flour. Mix until well combined.
Add in the oil and mix by hand or in a food processor for 6 to 8 minutes. Cover the bowl and let the dough rise for 90 minutes in a warm, dry place. Dough should double in size.
Preheat the oven to 425 degrees F and if possible, use a baking stone.
Punch the dough down and divide it into 8 pieces. Roll them into balls, then cover and let rest for 20 minutes to let the dough relax.
Dust a clean work surface with flour, then roll each ball out to 1/8-inch thick and approximately 6 inches in diameter. Cook on baking stone until puffed and starting to brown about 6 minutes each side. Spritz the oven with water, during baking, to create nice crisp pitas.
